First of all, my purpose for building an AMD PC is for testing, so thermals are the most important factor, followed by performance. I want to build an AMD PC that is a similar as I can make it to my Intel PC.

Whichever CPU, mobo and RAM I buy should be as similar as possible to the 12700K, Asus TG H670 Pro Wifi D4 and Patriot Viper Steel 2x32GB 3600 MT/s CL18. As a note, my CPU doesn't seem to much care for being OC'd, and it doesn't take much to cause it to get so hot that performance declines rather than increasing.

AM4 is going to cost me less, but then I won't have a computer that can handle future improvements via PCIe gen 5 devices and whatever else AM5 has that AM4 doesn't. It seems like if I want something on a similar footing to the above, I need either the 5900X or 7900X, and an X mobo, preferably ASRock as I have a sour taste in my mouth from MSI repeatedly saying they're going to pay the rebate they owe me from last Black Friday (but don't), Asus poor customer care (although THEY promptly paid my rebate no problems!) and, well, heck, those two and Gigabyte have poor customer care from what I've experienced and heard. Why an X mobo? Well, I have 4 SSDs in my current PC, so it only seems right to be able to have 4 in the AMD PC (although it's not required) plus whatever other benefits X offers.
___
TL;DR: If everything goes all screwy, I will use this info for next year or later when I can safely make these purchases.

Explanation: Secondly, my situation is complicated because, frankly, Amazon and their workers comp company (a really scumbag company) Sedgwick, are making things difficult in the most subtle gaslighting manner that they can pull (unfortunately for them, I'm wise to Amazon's manipulations and deceit). I could be put on a 1-year medical leave at any moment, I've just had to fire the lawyer I hired to sue Sedgwick for refusing to help me with my work injury and he was obstructing the progress of my case, and there are other things, like the election. I could, very soon but probably December, find myself on a limited budget. Assuming all goes well, I'll buy the CPU, mobo and RAM during Black Friday. I do NOT buy from my employer as I'm fed up with their unethical and sometimes illegal treatment of employees, so if anyone has suggestions as to which vendors are the best to go to to get great deals, that would be helpful. I will most likely shop at NewEgg and MicroCenter if I don't find anything better.
___
I already have 2 other ATX cases but they aren't big enough, so I must buy something that is comparable in size to my Corsair 5000X because I'll be testing large air and 360mm water CPU coolers, which is fairly easily accomplished in my 5000X.

Corsair5000XeATXCasespecs.thumb.png.f26698180ebba9eba38a56881a012276.png

However, this brings to mind questions, some of which are complicated, and I'm frankly not sure, especially because I've almost completely ignored AMD for 25 years. I ask that everyone answer the questions they definitely can and leave the rest for others to answer, and please let's stay on topic (which is as hard for me as it is for some other people LOL!).

Do not worry about coolers and fans, of which I have so many, or a PSU, as I have an EVGA 850 GQ Gold.

You may want to use PC Parts Picker, Pangoly, CPU Upgrade, Logical Increments, Choose My PC, MySetup.co, PC-Kombo, PCspecs, or BuildMyPC.

If you don't mind the risk of the apparent malware/spyware resident in the Capitol One Shopping extension, you can use that to shop Amazon and beat their prices. It infects any Chromium browsers, but I'm not sure what it does other than apparently spying. Again, I will NEVER buy on Amazon.

The Case Questions

Lights and color don't matter, but it must have USB 3.x and USB 3.x C gen 2 on the I/O panel; max air cooler height >=170mm; >=340mm GC (vertical mount isn't important unless it actually gives the card breathing room); and can hold the thickest 360mm rad complete with 30mm fans in front rad (my thickest is currently the LF3: 63mm); and is compatible with an ATX mobo. If also prefer that it's not difficult to work in. Most other things I'm flexible on, aside from the fact that it should be similar to the Corsair 5000X but not significantly larger or smaller than the 5000X, though, just because some AIOs have really short tubes.
  1. Would it be better for me to find a different type of (e)ATX case, maybe a terrarium? I don't feel like it would be a good idea since the differences would potentially really throw off results in comparison to the 5000X. I also wouldn't mind getting one (<$100) at some point, so here are some possibilities:
  2. Here are several I think meet my needs and are <$100. Does anyone have any suggestions? Here are some possiblities:
The CPU Questions
  1. Keeping in mind that this is for thermal testing and I need a CPU that is as similar to a 12700K as possible, should I get a 5900X, a 7900X or something else? I understand that PCIe gen 5 is going to be a big thing in the future, so perhaps the 7900X would be better despite the hundreds of extra dollars I'll need?
  2. I know I've stated that I want to aim for comparable results between AMD and Intel, but would it be strongly worthwhile for me to get a newer, hot AMD CPU, considering that only a minority of people would have those? I don't feel like it would, given the small number of people it would help, and people should be able to extrapolate from older CPUs how a cooler will work on a newer one...In theory!
  3. Are test results from actual CPUs OR from a dummy heat source that could be ramped up to as high a temperature as the hottest OC'd CPU can handle a better choice? Using a dummy heat source would certainly simplify some things for me, like not having to spend lots of money and needing space (and more parts) for two computers!
The Mobo Questions
The reason I chose X mobos is because my H670 Pro has 4 slots and I'm trying to keep the two builds as similar as possible.

  1. I'm inclined to buy an ASRock mobo if I can find a really good X variant with 4 M.2 slots, since I'm told that there are no 4-slot B mobos. Is that correct? AND which ASRock mobos would be the best ones to consider?
  2. If you think ASROCK X mobos aren't a good idea, what would you suggest instead, and why?
The RAM Questions
  1. I understand that AM4 prefers 4 sticks but AM5 prefers 2. Is there any reason I shouldn't go with the RAM suggestions below?
    Quote
    On DDR4 it was better with dual rank, which was generally easiest to obtain with 4x8GB compared to 2x16GB, though 2x16GB dual rank was still generally easier to use. On DDR5 you want to avoid 4 sticks if possible.
    If you're going AM4, get some cheap 3200 CL16 kit as spending any more on RAM doesn't make sense. If you go DDR5, 6000 CL30 is usually the best value.
    1728235004304.gif
  2. Is there any reason I shouldn't get 3600 MT/s or something else? My PC now has 3600 MT/s CL18 RAM.
  3. Is there any reason I shouldn't get 64GB? That's what I have now and, again, I'm trying to keep things as similar as I can.
  4. Is there any reason to look at single rank?
  5. Are there any other things I should be paying attention to for RAM?

Did I miss anything? Thank you!

7900X is faster.

Did I just save you a bunch of money??

I know, and the 5900X is slower, plus AM4 vs 5, cores, threads, etc. There is no exact equivalent.
I would say maybe to make it closer, do 8P vs 8P, shutting off E-Cores on the Intel chip.

And leaving performance on the Intel with ddr4 also, or is it ddr4 platform comparison only?

My Intel is DDR4, and I'm leaning towards the 7900X because of compatibility with future tech.

Sounds like a fun chip honestly. I may jump blue ship to red myself in the coming new years. This one is on the radar along with 9000 series.

12700K is a monolythic CPU with a huge die and a lot of TDP. Looks like that:
1728255123871.png

Ryzen CPUs are made like that:
1728254679363.jpeg

Which means that despite consuming MUCH less power they are as hard to cool if not harder. Multiple small dies, thermal transfer laws, yadda, yadda.
You shall need to keep it simple and go for a Ryzen 8700G which, delidded, looks like this:
1728254799555.png

You get it right. It's a one-die CPU. Of course it doesn't have a dozen cores and is made of vastly different arch and also doesn't achieve as much performance but it's as close to 12700K in terms of heat dissipation philosophy as humanly possible.

Now that you've witnessed all that you are in clear a dummy heater won't cut it. Dummy heat transfer is much more efficient than in any CPU.

You might also consider Ryzen 5700G:
1728255020753.png

But this is an AM4 option: cheaper, yet no PCI-e 5.0 and all those new bells'n'whistles. Can't decide for you, I got no idea what you're gonna do apart from testing your coolers.

RAM:
1. There's no reason.
2. There's no reason.
3. There's no reason. But if your tasks don't even remotely need that much you might as well settle for less. Heat won't differ significantly.
4. They clock much better than dual ranks of similar quality. However, dual ranks are faster at same speed/timings. For cooler testing purposes, it doesn't matter, just get whatever is best for its money and keep in mind you need tighter timings and higher clocks on single rank RAM.
5. Don't use Corsair Vengeance RAM with AM4. They don't like each other.

Can't really help with any other of your questions.

Why do you think it's a fun CPU?
For me it will be interesting (fun) to play with AMDs first LGA platform for starters. And because I enjoy sub zero cooling, would like to see how far I can go.

I just discovered that the Cooler Master MB600 is limited to 27mm for the rad thickness in front. :( Got that from the review here.

I also looked at 4 sites for thermal results and the Corsair 5000X seems to be about 5 C cooler for the CPU than the Antec P20C.

Great, thanks!
This is the first I've seen of these CPUs, and I don't know what the G means. I certainly appreciate this but, realistically, how many people use a monolithic CPU these days versus the newer offset chips? There's no point in getting a monolithic AMD if it's not going to prove helpful for those people looking at the offset CPUs, and am I correct in thinking: "What would be the point of building an AMD PC if it's going to have test results like the 12700k since the heat's in the same spot?" Please correct me if that's wrong!

Yeah, the most popular layout is multi-chip if you ask AMD buyers today.

Need similarity to 12700K, I told you what to get.
Need similarity to most AM4 users, get 5600X/5800X.
Need similarity to most AM5 users, get 7600/7700 and their X counterparts. 7500F is fine too.
Need similarity to workstation users, get whatever *900/*950 CPU. They roughly behave the same. *950 ones are much better for some 6 outta 8 core reason in *900 CPUs but I'm no expert.

G simply means it's a gaming oriented APU with somewhat limited overall computing power (mostly due to less L3 cache) and an iGPU that can actually be useful for gaming (in case of 8700G, one should expect something along the lines of RX 6400/6500 XT, or GTX 1060/1650/Super level performance depending on RAM speed and a game).

Your test results for AM5 won't differ that much from those for AM4 so if you target wide audience you should add, "results for 5800X will be similar but not exactly the same" or something along those lines. Also no point picking 12700K clones if you target wide.

Thanks again. Just curious, would I cast a wider net with the 5600X/5800X/7600/7700 and their X counterparts, and 7500F; or with the 5900X/7900X and...? What about the latency in dual CCD CPUs - is it worth being concerned about for my purposes (I don't think so?)?

You can theoretically disable one CCD so your 5950X suddenly becomes a weird 5800X so you test it in all kamasutra poses but that's just my speculations, I never owned a high tier AM4 CPU and never tested them. My guess this doesn't make these tests any dirtier than just slotting a real 5800X in but we need a confirmation from someone who has real XP on this matter. In case I'm right you should buy a workstation CPU and temporarily disable a half of it for "gaming" testing purposes.

Speaking of latency, I don't see how it can impact your cooler tests but it might be annoying in gaming, mostly competitive one; very rarely other tasks.

Thermal testing for maximum heat generation? For maximum heat dissipation? For testing different cooling rigs? What kind of thermal testing are we talking about? You could use the exact same parts as your intel rig except MB and CPU (wanting them to be as similar as possible, right?). Seems like that is the only way to get any kind of valid comparison, a least as far as thermals are concerned.

Well you could get a cheap Air cooler and then get a 5950x. You will know whether or not the thermals can work with that. That is the issue with your theory. Any CPU can reach it's thermal limits if you don't use the correct cooling. I am not saying the CPU will not work but will not run at at it's highest rated speed.

From my experience with single CCD Zen 5, I'd give that line of CPUs a go for the scenario you describe above. The thermals I get from that leave the Zen 4 line for dead literally in both idle & full load conditions. 4nm fabrication has worked well here.
You said similar to 12700K, so if you need the e-cores for extra thread capability then go with a dual CCD Zen 5, but you'll be paying more $. Another alternative I'd suggest is from the 8000 series of APUs from AMD like an 8700G (16 thread) , because this line of processors have mobile tech involved, they run substantially cooler than any AM5 chips to date & their FCLK overclocking is also substantially better than any other AM5 chip released to marker to far.

Thermal testing for maximum heat generation? For maximum heat dissipation? For testing different cooling rigs? What kind of thermal testing are we talking about? You could use the exact same parts as your intel rig except MB and CPU (wanting them to be as similar as possible, right?). Seems like that is the only way to get any kind of valid comparison, a least as far as thermals are concerned.
Heart dissipation, conduction, etc, on many different coolers.

Not necessarily able to use the same RAM, either. I'm not asking about anything other than case, mobo, CPU and RAM because that is easy. And, yes, I agree that the more similarities, the better.

Cases SHOULD be easy except that the vast majority of companies don't publish things like max rad thickness. I guess they didn't notice the thickness of the Arctic LF series, and how many people buy it, or they just aren't smart enough. I've seen enough messages from people saying they can't install their rad because of clearance issues.

Well you could get a cheap Air cooler and then get a 5950x. You will know whether or not the thermals can work with that. That is the issue with your theory. Any CPU can reach it's thermal limits if you don't use the correct cooling. I am not saying the CPU will not work but will not run at at it's highest rated speed.
Again, I have many coolers. Not sure but it seems you've misunderstood my intent. I'm testing cooling devices and TIMs. Sorry if that wasn't clear.

Thanks, that's interesting info. I'm not looking at monolithic CPUs because then there's not much point in having 2 test PCs since the heat is similar. The offset chips is what makes it necessary. I also don't need a cool chip because that is going to make it harder to really stress the big coolers, which is why I'm looking at 5900x and 7900x.


With the above in mind, what does everyone suggest?

Those CPUs do not produce lots of heat. Neither comes close to 200 Watts of power draw. The fact that they have 2 less cores on the die also means that those will run cooler than the 50x series CPUs. Just by raw transistor count. A 5900X is actually easier to cool than a 5800x though. If you want to test TIM performance and cooler tech then I would honestly get a 5950X or 14900K..

So here's a question. My idea is to have 2 PCs with similar heat production, a sort of cross-platform comparability. I already have the 12700k, and the 5900X and 7900X were suggested as being the most similar. I'm not going to upgrade my Intel.

Can you give me a compelling argument for why I should go to the hotter 5950X, instead of those or the AM5 equivalent?

Also, I am leaning towards AM5 because it has features lacking from AM4 that I think will allow it to be viable longer. Thoughts?

FYI, I'm not sure when I'll be able to do this project because it looks like Amazon will put me on a forced 1-year leave of absence on Dec 16th due to a work injury that Sedgwick refuses to pay for surgery for.

The only reason to get a 5950x is cost it will be cheaper at every level. I am not saying not to get a 7900X. I am already on AM5 and have a 7900X3D. Where you will find heat on AM4/5 MBs if you fill all of the storage that is connected to the chipset. Having said that AM5 is that much better than AM4 in terms of longevity. One of AMD's foundational principles is socket support longevity. Though we have gotten new chips for AM4 as recently as a couple months ago the best AM4 boards are out of production Asus B550XE, MSI X570S Aced Max). If you want flexibility other than all M2 or want to use an adapter card X670E boards like the X670E Strix E, MSI X670E Carbon and As Rock Taichi have full x4x4 support on the 2nd PCI E slot. An adapter card with a fan is much better at cooling an M2 drive than the heatsink and some even have that for the money you spend. That matters to me because I am into storage. Where you want to see TIM difference and cooler perfomance difference I love to test and use different types of NAND flash. So X870E boards are a huge nothing burger for me.

Why do I love storage? RAID 0. I don't care what anyone tells me RAID 0 on NAND flash feels faster and more stable.


This is why Unions matter. That is bullshit. I don't want to make you feel bad but if I had an at work injury. My workplace would pay 67% of my wage and the Govt would pay the other 23% (To a maximum). I hope you get better soon though. I don't have any AM5 boards but I could send you an AM4 board to save a little. because I am intersted in what you want to do. You deserve something for an event that occured while you were working.

Update: I was just told that, unless I'm willing to return to full duty with my injury, I am on a forced medical leave of absence starting tomorrow, and I don't know when it will end. Naturally, I told them that I can't go back to full duty.

I'll probably be able to get 60% pay, but then taxes and benefits are subtracted, dropping that down to probably 30%... sub-poverty.

Also, I fired my workers comp lawyer for repeatedly lying to me and hindering my case. Seems likely that Sedgwick is behind it since it's not the first time a WC lawyer screwed me on this.

Thanks for all the info, very useful!

I don't really understand why people are so down on RAID. Do you?

Yeah, we've been trying to unionize since the end of 2022, but Anson used unethical and even illegal tactics to stop us. Now, we are starting over with the Teamsters.

I can't get better without surgery, just worse. been denied twice even though it happened at work.

Thank you, I really appreciate your support! Please DM me about the mobo.

Anyone that hates RAID 0 has read about the downsides of RAID 0 Too bad that was in the time of HDD. With SSD there are no moving parts to worry about. As far as I am concerned the endurance is doubled as well.

Updates:
  • Max AIO depth of the Antec case is ~92mm, and width is 140mm, which makes it big enough for the LF3 (33mm + 38mm fans), and the Hyte Thicc Q60 (52mm plus fans).
  • The Segotep & MasterBox do not offer enough depth for an LF3 or Q60 with thicker fans.
  • I'm no longer considering the first 3 cases (bgears, Gamemax & SAMA)
  • The bq! DB 500 has poor frontal airflow.
  • The Cougar comes with both solid and mesh panels.
Added:

I asked Tony Oh, the SilverStone marketing manager, and he said he doesn't have any that meet the requirements.
Segotep declined to answer my question.

Ok, so that makes sense. Is there an equivalent hot CPU in the 7xxxs?

Update: I just got a call that my accommodations request has been approved, so I'm back at work tomorrow. This is such a relief!

I have another question, and maybe this is better. Honestly, it's because of comments I've received that set me to pondering.

Instead of going for a comparable CPU, should I get a hotter one? I mean, I am going to be testing thermals so buying something that's not so hot, like the equivalent of the 12700k, is going to give different results unless I can learn how to OC the 12700k so that it gets hotter without losing performance. I tried but I'm a rank novice at OCing, so I probably did it wrong!

The question I have, aside from what're the hottest AM4 and AM5 CPUs that are worth investing in, is whether people are going to start comparing the Intel and AMD results and not notice the difference in heat output from the 2 CPUs, and then get some wacky wrong ideas.

Does anyone have any thoughts?
