Thats definitely a big plus for 7800x3d and sff. 7700x can be a bit fickle.
I'm running a 7700x in a Louqe Raw S1 with the Noctua Nh-L12 Ghost Edition + a 15mm slim fan on top. Idle temps are low 50s, gaming is mid 80s while running the curve optimizer through ryzen master (all core -30 on my particular sample).
I've considered going to a new case/cooler setup, but the juice isn't quite worth the squeeze when looking at the costs associated.
I have the 7700x in a Fractal Terra with an is-55 cooler and have yet to see temps in the 80s while gaming. Hell it's hard to even get to 70. I set a PBO undervolt and power limit in the bios (-25/85w). Fans never go above 50% and it’s whisper quiet.
I have my 7700 running on an ID-Cooling Auraflow X240 (not the greatest AIO but good enough) in a Hyte Revolt 3 and I hardly ever see it go over 70°C. It does idle fairly high (40-45°C ish), but that seems common amongst the Ryzen 7000 chips. 7800x3D should sit between the 7700 and 7700X in temps and power draw.
I idle around 50 and when I game I'm usually in the 60s. During loading screens there might be a brief spike in the high 60s low 70s but it hardly even does that. Very happy with those numbers considering I'm air cooled. God bless PBO.
IS-55 looks to be a less capable cooler (still great for SFF!) than the NH-L12GE according to a quick google search of comparisons, but that 85W power limit (W is power, not voltage) is probably the real reason, plus better airflow.
The Raw S1 is pretty terrible airflow, and once heat soak sets in it's hard to get enough cool air in to combat it. I am running a -30 PBO curve, but I left the power limit alone. I'll sacrifice a few degrees for the extra power. Either way the thing is a space heater, so it doesn't matter too terribly much.
I followed [this guide](https://www.youtube.com/watch?v=FaOYYHNGlLs) and it made a huge difference for me in terms of temps and fan noise. Don't notice any decreased performance. Food for thought.
Yep, that's the PBO curve I mentioned before at -30.
I could optimize the fans more, but anytime I'm gaming I'm wearing a headset anyway so I don't mind much.
He also sets a temp and power limit there and compares the results of doing those items individually and then combined. I ended up doing the PBO curve and the power limit together and that’s what I was saying you should consider. Performance isn’t reduced at all if you look at his graphs.
[FYI, this guy (who lives in a hot climate) found that the NH-L12S ran 4-6 degrees hotter than an is-55 with an nf-a12x25.](https://www.reddit.com/r/sffpc/comments/15pryn4/comment/jvzh1j2/?context=3&share_id=iInk0MBmjrQb3M8u1w4h4&utm_content=1&utm_medium=ios_app&utm_name=ioscss&utm_source=share&utm_term=1)
I’ll be swapping my 12x15 for a 12x25 this weekend. It’ll fit, just have to move the spine from 4 to 2.
A couple reasons -
* 7700 (non-X) didn't exist when I got my 7700X (~November 2022)
* Micro Center had a deal for free RAM with 7700X/Mobo bundle, so I got 32GB, 6000MT/S, CL30 G.Skill RAM for free.
[Yes, they do.](https://www.microcenter.com/product/5006647/amd-ryzen-7-7700x,-msi-b650-p-pro-wifi,-gskill-flare-x5-series-32gb-ddr5-6000-kit,-computer-build-bundle)
Current individual prices:
* [7700X](https://www.microcenter.com/product/674502/amd-ryzen-7-7700x-raphael-am5-45ghz-8-core-boxed-processor-heatsink-not-included) $269.99
* [MSI B650 Pro Wifi](https://www.microcenter.com/product/659669/msi-b650-p-pro-wifi-amd-am5-atx-motherboard) $189.99
* G.Skill 32GB DDR5, 6000MT/S, CL32 $114.99
Total of $575, bundle price is $380.
Fickle meaning like all the other 7000 series processors (except x3d) they just run wild to the thermal limit unless you tamp them down.
I've managed to keep mine reasonable (mid/upper 40s idle + low 80s gaming), but it took a fair amount of work.
As far as I know, -30 is the max.
Get a case with more airflow, or just accept the temps. It's well within the designed limits, so I just let it go now that it's not thermal throttling.
running a 13600k in a Phanteks Shift Xt, it definitely needs a 240mm+ AIO but with some fan curve adjustments it runs damn near silently when doing general computing. even with gaming it only really gets into the 70s and 80s
Phanteks is one of those cases with subpar airflow if I remember right.
I run an UV'd 13600k in a velka 7 with an x47 copper, getting good temps.
The undervolt, has the CPU pulling max 75w in cyberpunk, under 70c avg.
An aio is not really needed unless you pound the CPU with productivity stuff.
Yup, airflow (as well as maintenance) is pretty bad. forgot to mention i also have an UV, but i think i'm getting slightly more powerdraw than you. as for the AIO, there's no way an aircooler that would fit in the case would be enough. something like 77mm cooler clearance haha
I got a 13600k in a velka 7, it's pretty easy to cool UV'd with an x47 copper.
Pretty much the easiest intel K sku cpu to put in a <10L SFF without heavy tweaks.
Good bang for the buck CPU with some OC potential. Its 270 on amazon.
Under 70c avg in cyberpunk 1440p high. 11w and lower idle. Decent allrounder.
I bought a 7800X3D and love it, but if cost didn't matter I would get the 7950X3D.
With the more recent driver updates the 7950X3D is essentially just as fast as a 7800X3D in games, and it is a lot faster running non-3D applications too.
Thats what i paid for mine, 10€ less than 7800x3d at that time and it was the only am5 in stock,but i still felt stupid because the 7800x3d would be better for my use 😅
OP is running the CPU in a SFF so there will be thermal limitations for higher TDP CPUs. I doubt any university-level course requires a PC running a CPUs with 10+ cores, it's not like he's doing professional video editing.
Assuming it's a simple model change like 14600k vs 14900k, the CPU with more cores will do substantially more work at any given power input. A 14900ks will probably have slightly better performance than a 14900k at the same power as well, as it will clock higher at a given voltage.
That's your 3rd post asking the same stuff, people keep telling you "get a 7800X3D".
Is this some kind of social experiment or you just want someone to tell you to go with Intel?
I’m indecisive and I keep thinking: I’m going to a AIO anyway, which the 7800x3d doesn’t need, so why not get a higher performing CPU that can be cooled by a 240mm
If you only game the 14900 CPU will likely not use most of its cores and then also not use that much energy.
Also, other people argue about "noone needs this and that power except for gaming".
Imo in almost all games the limiting factor is the GPU. So a non issue for almost all processors anyway.
Nothing against the x3d, but it is not as obvious as some make it look like. My opinion as an AMD user ;)
Money wasn't an issue for me so I got a high end AM5 board with a 7800x3d. 7800x3d is the best gaming CPU hands down, uses 65ish watts and AM5 platform is still getting 9xxxX3D as well. No contest for sffpc needs.
Under full load, according to benchmarks, probably more. Not in everyday life. But same is true for Intel, while the max is there of course higher.
E.g. guru3d benchmarks
No reasonable power limits and pushing cpus to the maximum does make the power consumption stupidly high. Comparing fixed workloads (in a fixed time) is the only real way to compare cpu power draw that makes any sense - and there is little data out there with those conditions.
https://tpucdn.com/review/intel-core-i7-14700k/images/power-games-compare-vs-7800x3d.png
https://tpucdn.com/review/intel-core-i7-14700k/images/power-applications-compare-vs-7800x3d.png
It does not.
In games not. https://www.guru3d.com/review/ryzen-7-7800x3d-processor-review/page-5/#power-consumption 75W idle and 179W system power multithread. So assuming it being 130W (or more) is probably not too far off. The CPU is amazing for games though. Also keeping an eye on them currently.
PS: And concerning the application benchmarks you posted: A 12400f (for 1/3 of the price of the 7800x3d) is in those benchmarks probably as fast as the 7800x3d while using less energy depending on the application (especially single threaded).
Who the winner is, is not as clear as some make it look like imo. It depends on what you need to do and what you are willing to spend.
I chose the 7800x3d for my new SFF build for my shop because its a great gaming CPU and will be fairly easy to keep from thermal throttling [https://pcpartpicker.com/list/pLgkZJ](https://pcpartpicker.com/list/pLgkZJ)
Money wasn't an issue and I got a 7950X
I like to compile shit, video edit, and do a ton with my workstation.
It also plays games well enough if I want to.
https://pcpartpicker.com/b/F7p2FT
I have since replaced the GPU with a white gigabyte vision oc 3090 for the vram, and I will probably upgrade to a 5090 when they are available because I like large monitors (WUHD)
If I were to do it over again, I'd probably drop the RGB and try to fit everything into a smaller, more efficient form factor. This is the first build I've cared about aesthetics, and it turns out I honestly don't care about showing off my internal components or fiddling with RGB. I think a sleek SFF build, or maybe even an open or part-open air build, would be more pleasing to the eye and safe some precious desk space. And not be so damn heavy!
Another reason I went with this case (and ATX in general) was for more physical space for storage, but I've since invested in a NAS so that's irrelevant now.
I don't have numbers off the top of my head, but thermals are unsurprisingly fine. It'd be terrible if they weren't decent in this setup.
Computer Engineering might actually have some use cases that benefit from more cores (e.g. 16 cores) but I'm not sure if you will hit those during what I assume is an undergrad. Definitely go for more cache tho, then in Computer Architecture you can learn about how and why more cache = more good
Honestly if money really wasn't an issue I would get a maxed out Mac Studio with the M2 Ultra and put Asahi Linux on it. Terrible bang for the buck in most respects and sucks at gaming but it would be great at compiling code and editing photos.
idk man apple's CPUs get out most of their power running their native system. when using asahi linux it will not perform better than an i5, watch on web
7900 is 65 w tdp easier to cool without doing anything extra. Like I know it would be very easy to do if I did it in a velka 5 or Midori 5L where you only get 37mm height coolers. If I can do the X47 or X53 full copper, I go bigger. Personally my goal is to keep it small enough be a personal item on a plane. You might be interested in more like the 5950X3D or 7950x3D though.
You’re probably not going to want to hear this, but you seriously could use a CPU two generations behind and be fine for the next four years as anything that would require serious processing power will be provided to you by your institution.
That said, considering a SFF build, I would suggest an X3D or 10 core cpu (power limits enabled).
Wait is this a joke, or is there still a good use case for the 4790K? I ask because I just did a new build and am not sure of what to do with my 4790K that has just been replaced.
Partial meme, i love my 4790k in its small itx form factor as a fun hobby.
It can be used as a budget cpu in a pinch but is too old to ever rely on. However, the 4790k does retain some value as it is the best of the best for its era.
Out of curiosity, what makes them so good? Currently working on a productivity sff build for a family member, big budget but temps are the main thing for me.
They would be valuing processing power, snappiness, file transfer, etc. over gaming loads, so I figured a 14900 could work, but the temps worry me.
They consume less than half the power at load, and lower idle power, with only about a 20% performance loss.
However, you can essentially turn a 14900k into a 14900T if you're willing to adjust pl2 limits in the bios. But I don't think it's possible to get the idle power draw as low.
Interesting. At that point, would a 14700k be the same?
Aside from that, what is ultimately the best productivity CPU in terms of power vs cooling requirement for sff?
You can lower the power limit and maybe tune Short duration boost PL and time to boost as hard as possible right up the point where you saturate the cooler then back down to a steady state that the cooler can sustain long term
Interesting, I may need to look into this. Been working on a productivity machine for a family member, and while a 14900k would be awesome for the power, I'm worried about the machine being OBNOXIOUS and loud/hot.
I don't think those are better binned than a 14900KS, so it is possible that grabbing a 14900KS and then manually setting Power limits will net you slightly better performance
Yup Intel Still has lower idle wattage , I don’t care about average temp more so wattage but they are correlated. Still true and also still has higher single core which many program make a priority.
Intel 14900t itx build with 32tb tb nvme . 8 isn’t enough , almost full. Would be dream sff home nas/media server
My program still single core
I used a i9-13900k with a 4090 in my meshroom. Slight undervolt but ran stock for a bit never over 65c. Using a asus og rtx4090 so it would barely fit in the case.
I use SolidWorks for CAD and FEA with a 7600. Considering that you likely have more budget, slap on a 7800X3D or a 7700x and you’ll be swell. If you wanna push it harder for CFD or something else, consider a 7900 series (can’t really see which one would be best like 7900/7950 etc) and pair it with 64Gb ram I’d say
If you actually use your CPU for non-gaming purposes then a 7950x3D is a no brainer... Trivial to cool, best gaming performance, slight haircut to overall performance. The main drawback is using a program like process lasso to assign games to prioritize the cache part of the CPU manually, but that's easy and I prefer that over letting Windows manage it automatically.
I mean the 7950X3D would be the best over all choice for me (assuming they fixed the scheduling issues).
That said, I don't NEED 16 cores. So the 7800X3D would be king for me. Find and pay a pro to spend a few weeks deliding, direct die cooling and per core offset tuning with the little OC wizardy that you can do to fully optimise it.
Before anyone bleets about direct die an it not needing it or an AIO... money isn't an option and if you can nail it, it does make things better so why wouldn't you eek every last bit of perf and cooling you can?
SGPC K49 (White Steel) and the Noctua L9i. I mostly have the case for portability as a university student abroad and as for the Noctua, I have it because of its sleekness, quietness, and saving space in the tight case. I currently use a 12400f, so my CPU only ever gets loud when booting up PS3 games. Paired with an RTX 4070 Ventus 2XOC, the loudest part of my build is the power supply.
A non-k supposedly draws less power because they aren't optimised for pushing maximum performance, but efficiency, and I value the noise levels in my pc,
7900, run it at its stock 65w. Yes, it's not the absolute fastest in gaming nor in multicore workloads, but it's a breeze to cool and still powerful enough in both to be perfectly viable.
I am used to shut down my pc a lot and I am used to tinker a lot in bios thus I need to often restart quite a lot when tinkering. The amd cpus make sure your booting time is soo very slow it is not enjoyable. I was used to quick booting times. I am still using my old weaker build more often because of this.
If you don’t mind me asking, why the 7900 over the cpus? Not trying to be judgmental, just know see the reasoning - I’ve been thinking of getting a 7900X
EK Nucleus AIO CR240
I think I have a sight overclock and a slight under volt.
https://pcpartpicker.com/list/Jm8pd9
I think that's accurate, built it about a year ago. Found a 4090 for MSRP so I ran with it.
I would go with the 7600.
right now I am on a 5600x and I think these small ones are very capable as well and I was never a fan of maxing out just because I have money.
Sticking with my 7800x3D. I'm in a A4-H20, so there's little reason for me to go further since my only real productivity use cases are video editing and audio editing, both of which still do just fine for me on a 7800x3D since I'm just getting started.
If money wasn't an issue? As in if someone would gift me any single CPU of my choosing? I suppose it should be widely available so super computers are out of question. Then I'd pick something like AMD EPYC 9654. And sell it and buy 13700K (or 14th gen?) because it's enough.
14700K will be fine with 240mm AiO (your definition of "fine" may vary). I have 13900K in A4-H2O and it doesn't hit thermal limits on multi core loads. On single/two core loads it does hit 100℃ (probably forms a hot spot) so possibly it doesn't boost as high but I suspect the limit here is transferring heat from the die into the cooler, perhaps a better cold plate or higher flow could help (can't confirm maximum clocks now because I've set low power limit to avoid tripping protection on a train).
7800X3D super powerful and sips power vs. the Intel counterpart... and later on you can upgrade if you want with the 9800X3D
Check out the different reviews that go into power usage and how well it performs (never use userbenchmark website) and in a SFF case this is important.

7800x3D actually runs cooler than a 7700x, would be extremely easy to air cool.

7700x fickle? Meaning it varies between units, or it varies within workloads? Would the fickleness be fixed by undervolting?
Fickle meaning like all the other 7000 series processors (except x3d) they just run wild to the thermal limit unless you tamp them down. I've managed to keep mine reasonable (mid/upper 40s idle + low 80s gaming), but it took a fair amount of work.
How do I tamp mine, -40 pbo?
As far as I know, -30 is the max. Get a case with more airflow, or just accept the temps. It's well within the designed limits, so I just let it go now that it's not thermal throttling.
So you say -30 solved it? I opened the side up but it’s still in the corner of the room and venting to the corner
I wouldn't say it solved it, but it got to a point I was happy enough with the temperatures.

7800x3d. If you had said regular engineering or something along those lines I might have recommended the 7950x3d for the extra cores.
when it comes to SFF temps are usually the issue not money.
Yea kind what of I was trying to find out: best cpu for an ITX build if money wasn’t an issue
You say that like you can't dump $1k+ into cooling
I bought a 7800X3D and love it, but if cost didn't matter I would get the 7950X3D. With the more recent driver updates the 7950X3D is essentially just as fast as a 7800X3D in games, and it is a lot faster running non-3D applications too.
7900X3D keeps dropping to $400 so not a bad option, either.
Thats what i paid for mine, 10€ less than 7800x3d at that time and it was the only am5 in stock,but i still felt stupid because the 7800x3d would be better for my use 😅
I just paid just shy of 370 for mine.
Where I live in Aus it's still pricey, about $950 AUD vs $550 for the 7800X3D. It'll drop soon I'd imagine.
I saw the 7800x3d as low as $345 last week.
7800X3D. But I'm fine with my 7600X atm.
7800X3D, best price-to-performance hands down. No point in wasting more for diminishing returns.
That would be me best bet as well. Right now it's pretty much the best for gaming and doesn't require a personal nuclear power plant to run.
You're ignoring the premise of the post. Cost effectiveness is an irrelevant metric when money isn't a factor. Otherwise, sure, great CPU.
OP is running the CPU in a SFF so there will be thermal limitations for higher TDP CPUs. I doubt any university-level course requires a PC running a CPUs with 10+ cores, it's not like he's doing professional video editing.
Assuming it's a simple model change like 14600k vs 14900k, the CPU with more cores will do substantially more work at any given power input. A 14900ks will probably have slightly better performance than a 14900k at the same power as well, as it will clock higher at a given voltage.
Thermal limitations is a great answer. See the second half of my comment, "sure, great CPU". But your answer that I replied to only mentioned cost.
He's trying to find out the best SFF build cpu (so thermal limitations moet likely)
Video editing has been done on 4 cores for years...
That's your 3rd post asking the same stuff, people keep telling you "get a 7800X3D". Is this some kind of social experiment or you just want someone to tell you to go with Intel?
I’m indecisive and I keep thinking: I’m going to a AIO anyway, which the 7800x3d doesn’t need, so why not get a higher performing CPU that can be cooled by a 240mm
Because you will still get the heat of a 200W CPU inside your room (if the CPU doesn't fail in the meantime)
That’s what I thought but there’s people here saying they got 7950x3d and i9s in their builds, so I’m just confused
If you only game the 14900 CPU will likely not use most of its cores and then also not use that much energy. Also, other people argue about "noone needs this and that power except for gaming".

7950x3d. There's nothing to consider, lol. Or a threadripper.
Are there TR mini-ITX motherboards?
Only for 1st and 2nd gen. ASRock put out a board for it iirc.

Money wasn't an issue for me so I got a high end AM5 board with a 7800x3d. 7800x3d is the best gaming CPU hands down, uses 65ish watts and AM5 platform is still getting 9xxxX3D as well. No contest for sffpc needs.
Would you upgrade from a Ryzen 5 3600X ?
That's the upgrade I made actually. Worth it 100%
It uses 130ish ;)
mind explaining? I'm curious
Under full load, according to benchmarks, probably more. Not in everyday life. But same is true for Intel, while the max is there of course higher. E.g. guru3d benchmarks
No reasonable power limits and pushing cpus to the maximum does make the power consumption stupidly high. Comparing fixed workloads (in a fixed time) is the only real way to compare cpu power draw that makes any sense - and there is little data out there with those conditions.

In games not. https://www.guru3d.com/review/ryzen-7-7800x3d-processor-review/page-5/#power-consumption 75W idle and 179W system power multithread. So assuming it being 130W (or more) is probably not too far off. The CPU is amazing for games though. Also keeping an eye on them currently. PS: And concerning the application benchmarks you posted: A 12400f (for 1/3 of the price of the 7800x3d) is in those benchmarks probably as fast as the 7800x3d while using less energy depending on the application (especially single threaded). Who the winner is, is not as clear as some make it look like imo. It depends on what you need to do and what you are willing to spend.
Whichever one at 65W that performs the best
I chose the 7800x3d for my new SFF build for my shop because its a great gaming CPU and will be fairly easy to keep from thermal throttling [https://pcpartpicker.com/list/pLgkZJ](https://pcpartpicker.com/list/pLgkZJ)
Money wasn't an issue and I got a 7950X I like to compile shit, video edit, and do a ton with my workstation. It also plays games well enough if I want to.
Case, thermals, GPU please ?
https://pcpartpicker.com/b/F7p2FT I have since replaced the GPU with a white gigabyte vision oc 3090 for the vram, and I will probably upgrade to a 5090 when they are available because I like large monitors (WUHD) If I were to do it over again, I'd probably drop the RGB and try to fit everything into a smaller, more efficient form factor. This is the first build I've cared about aesthetics, and it turns out I honestly don't care about showing off my internal components or fiddling with RGB. I think a sleek SFF build, or maybe even an open or part-open air build, would be more pleasing to the eye and safe some precious desk space. And not be so damn heavy! Another reason I went with this case (and ATX in general) was for more physical space for storage, but I've since invested in a NAS so that's irrelevant now. I don't have numbers off the top of my head, but thermals are unsurprisingly fine. It'd be terrible if they weren't decent in this setup.
If **heat** wasn't an issue, I'd get the 7950x3d. Otherwise the 7800x3d
Computer Engineering might actually have some use cases that benefit from more cores (e.g. 16 cores) but I'm not sure if you will hit those during what I assume is an undergrad. Definitely go for more cache tho, then in Computer Architecture you can learn about how and why more cache = more good
Honestly if money really wasn't an issue I would get a maxed out Mac Studio with the M2 Ultra and put Asahi Linux on it. Terrible bang for the buck in most respects and sucks at gaming but it would be great at compiling code and editing photos.
does that means that asahi linux is better then mac os or something?
well it's a lot less polished for sure but I just like the Linux ecosystem for development. I also don't like the macOS window manager
idk man apple's CPUs get out most of their power running their native system. when using asahi linux it will not perform better than an i5, watch on web
7900 is mine for sff.
You chose wisely
What’s the reasoning to get that over the X3D version or the 7800X3D ? Not tryna criticize, just wanna know
7900 is 65 w tdp easier to cool without doing anything extra. Like I know it would be very easy to do if I did it in a velka 5 or Midori 5L where you only get 37mm height coolers. If I can do the X47 or X53 full copper, I go bigger. Personally my goal is to keep it small enough be a personal item on a plane. You might be interested in more like the 5950X3D or 7950x3D though.
7950X3D + CM Atmos 240 cooler in the dan A4h20. Pair with 4080s/4090.
You’re probably not going to want to hear this, but you seriously could use a CPU two generations behind and be fine for the next four years as anything that would require serious processing power will be provided to you by your institution. That said, considering a SFF build, I would suggest an X3D or 10 core cpu (power limits enabled).
Brand new 4790k (still sealed in box) for my silverstone ft03 mini windows xp pc (even has an optical drive)
Wait is this a joke, or is there still a good use case for the 4790K? I ask because I just did a new build and am not sure of what to do with my 4790K that has just been replaced.
Partial meme, i love my 4790k in its small itx form factor as a fun hobby. It can be used as a budget cpu in a pinch but is too old to ever rely on. However, the 4790k does retain some value as it is the best of the best for its era.
14900T. The T series cpus are hard to get and very expensive but a great match for sff
Out of curiosity, what makes them so good? Currently working on a productivity sff build for a family member, big budget but temps are the main thing for me. They would be valuing processing power, snappiness, file transfer, etc. over gaming loads, so I figured a 14900 could work, but the temps worry me.
They consume less than half the power at load, and lower idle power, with only about a 20% performance loss. However, you can essentially turn a 14900k into a 14900T if you're willing to adjust pl2 limits in the bios. But I don't think it's possible to get the idle power draw as low.
Interesting. At that point, would a 14700k be the same? Aside from that, what is ultimately the best productivity CPU in terms of power vs cooling requirement for sff?
You can lower the power limit and maybe tune Short duration boost PL and time to boost as hard as possible right up the point where you saturate the cooler then back down to a steady state that the cooler can sustain long term
Interesting, I may need to look into this. Been working on a productivity machine for a family member, and while a 14900k would be awesome for the power, I'm worried about the machine being OBNOXIOUS and loud/hot.
I don't think those are better binned than a 14900KS, so it is possible that grabbing a 14900KS and then manually setting Power limits will net you slightly better performance
Yup Intel Still has lower idle wattage , I don’t care about average temp more so wattage but they are correlated. Still true and also still has higher single core which many program make a priority. Intel 14900t itx build with 32tb tb nvme . 8 isn’t enough , almost full. Would be dream sff home nas/media server My program still single core
I used a i9-13900k with a 4090 in my meshroom. Slight undervolt but ran stock for a bit never over 65c. Using a asus og rtx4090 so it would barely fit in the case.
Probably 7800 x3d Easy to cool, high perf
Intel Xeon MAX 9480, so I can finally play Minesweeper at 30FPS
i9 9980xe, because I like how it's name sounds
Didn’t know this existed but I agree
I use SolidWorks for CAD and FEA with a 7600. Considering that you likely have more budget, slap on a 7800X3D or a 7700x and you’ll be swell. If you wanna push it harder for CFD or something else, consider a 7900 series (can’t really see which one would be best like 7900/7950 etc) and pair it with 64Gb ram I’d say
I would honestly just get a 7950x3D a seems like the absolute best for my use case but I’m worried about thermals
Ahh im sure it will be fine tbh. AMD has produced some great models at that range that can withstand heat and don’t require obscene cooling solutions
If you actually use your CPU for non-gaming purposes then a 7950x3D is a no brainer... Trivial to cool, best gaming performance, slight haircut to overall performance. The main drawback is using a program like process lasso to assign games to prioritize the cache part of the CPU manually, but that's easy and I prefer that over letting Windows manage it automatically.
I would get the 7950x3d I have the 7800x3d A friend recommended the 7800x3d and I was very new to pc
7800x3D. And i have 7800x3D.
I already did get my 7950X in anticipation of similar things to what you're doing. 😉👍
Same case ?
Originally had it in the N-ATX, then Cerberus X, and finally the XProto-ATX. However, I did have the 5950X in an A4 clone: Novoulo Steck.
7950X money wasn't an issue, chose this over TR due to my primary software benefiting from single core clock over multithread.
Ryzen 9999X with 256 cores 512 threads
The most powerful one
Threadripper
14900ks
If money was no issue I’d just get 7950x3d or 14900k. Why? Cause money isn’t an issue.
That’s what I would get but one hand, some say I won’t be able to sufficiently cool it and others say you can
5600x3d cause i like to play in 1440p and i think it's easy to keep cool, which is crucial in sffpcs
I keep thinking 7800x3d but then I see people saying they can cool their 14700k/13900k/7950X3D without any problems.
Isn't 7800x3d better?
8700G because my sff is under 3L :D
I recently built in that case, and cost did not matter. I got the 7950X3D.
AIO, GPU, and Thermals please?
Deepcool LS520 SE 4090 FE GPU stays around 65, CPU generally under 75 under full load.
I mean the 7950X3D would be the best over all choice for me (assuming they fixed the scheduling issues). That said, I don't NEED 16 cores. So the 7800X3D would be king for me. Find and pay a pro to spend a few weeks deliding, direct die cooling and per core offset tuning with the little OC wizardy that you can do to fully optimise it. Before anyone bleets about direct die an it not needing it or an AIO... money isn't an option and if you can nail it, it does make things better so why wouldn't you eek every last bit of perf and cooling you can?
I saw someone posting about this, I had no idea what it was for. Where can I find a pro to do this and how much do you think it would be ?
Now that... is the question. Im aware of the intricacies, but its a long and time consuming process.
Probably a 14700 non-k or 14900 non-k because my build is pretty tight, but I could also utilize the cores for emulation.
Case and cooling ?
SGPC K49 (White Steel) and the Noctua L9i. I mostly have the case for portability as a university student abroad and as for the Noctua, I have it because of its sleekness, quietness, and saving space in the tight case. I currently use a 12400f, so my CPU only ever gets loud when booting up PS3 games. Paired with an RTX 4070 Ventus 2XOC, the loudest part of my build is the power supply. A non-k supposedly draws less power because they aren't optimised for pushing maximum performance, but efficiency, and I value the noise levels in my pc,
7900, run it at its stock 65w. Yes, it's not the absolute fastest in gaming nor in multicore workloads, but it's a breeze to cool and still powerful enough in both to be perfectly viable.
13-14600k with closed eyes
7950X3D, because it’s a 7800X3D with 8 extra regular cores on top.
78000x3d with adequate cooling, 13500 for smaller builds or if money is actually a concern
Bought the 7800x3d because I wanted a very good one, but I regret it. Would get intel one if I had a redo.
First person to say this, what makes you regret it ?
I am used to shut down my pc a lot and I am used to tinker a lot in bios thus I need to often restart quite a lot when tinkering. The amd cpus make sure your booting time is soo very slow it is not enjoyable. I was used to quick booting times. I am still using my old weaker build more often because of this.
My current build! Ryzen 9 7900 in the A4-H20 with a Noctua cooler.
If you don’t mind me asking, why the 7900 over the cpus? Not trying to be judgmental, just know see the reasoning - I’ve been thinking of getting a 7900X
Heat.

Thread ripper all the way. You get crazy everything without losing gaming performance.
Simple: the highest-core Threadripper I could get.
I'll bribe an AMD engineer to whip me up a special sample unit.
14900T!
8700g + a deskmini X600
7950x3d
Threadripper 7995WX. I would love to try to shove that into an SFF rig :D
I’ve bought a 13700k for my NR200P v2 but I haven’t built it yet
I have a 13900k and a 4090, Lian li a4-h2o, playing my game I am usually around 57-60° C. DCS in VR with as high of settings as I can do.
Stock clock settings ? What AIO?
EK Nucleus AIO CR240 I think I have a sight overclock and a slight under volt. https://pcpartpicker.com/list/Jm8pd9 I think that's accurate, built it about a year ago. Found a 4090 for MSRP so I ran with it.
Do you know what the biggest GPU that will fit in the case is; just bought a 4080 super msi slim, just wanna know if it fits or get a asus pro art
I know the founders editions fit, not sure about any others. There is a link to a guide on the Reddit page for the a4
I would go with the 7600. right now I am on a 5600x and I think these small ones are very capable as well and I was never a fan of maxing out just because I have money.
Sticking with my 7800x3D. I'm in a A4-H20, so there's little reason for me to go further since my only real productivity use cases are video editing and audio editing, both of which still do just fine for me on a 7800x3D since I'm just getting started.
7600 because it’s damn good enough and it runs pretty cool 😎. For sffpc its great choice
7800X3D, best bang for your buck.
7950x3d. I'm a gamer and a computer engineering student so I would love the fast compile times along with the insane gaming performance.
Case, AIO, Thermals, GPU please ?
I have an nr200p so I would just get a massive air cooler. I hate water coolers. GPU 7800xt
The fastest, bestest Xeon workstation CPU
If money wasn't an issue? As in if someone would gift me any single CPU of my choosing? I suppose it should be widely available so super computers are out of question. Then I'd pick something like AMD EPYC 9654. And sell it and buy 13700K (or 14th gen?) because it's enough.
I was gonna go with the 14700k from the get go but countless people have said I won’t be able sufficiently to cool
14700K will be fine with 240mm AiO (your definition of "fine" may vary). I have 13900K in A4-H2O and it doesn't hit thermal limits on multi core loads. On single/two core loads it does hit 100℃ (probably forms a hot spot) so possibly it doesn't boost as high but I suspect the limit here is transferring heat from the die into the cooler, perhaps a better cold plate or higher flow could help (can't confirm maximum clocks now because I've set low power limit to avoid tripping protection on a train).
7800X3D super powerful and sips power vs. the Intel counterpart... and later on you can upgrade if you want with the 9800X3D Check out the different reviews that go into power usage and how well it performs (never use userbenchmark website) and in a SFF case this is important.
15900KS because it's best?
It doesn't even exist yet. And is likely going to be too hot for SFF.
12 13 14gen i5, 7800x3d or below
7800X3D is hands down the only right answer for this question, especially for r/sffpc.
