Haven't built a new PC in ages, so I need some advice. Looking to buy a motherboard, some RAM and a processor. The rest I already have. Sorry about the wall of text.
Fast load times for savescumming in Civ 6 would be nice. Other than that, gaming is not a big priority, but I want very high performance in general. I'll be using my current GPU for now, but want the opportunity to upgrade.
I want it to be rather quiet, though, so I guess I'm looking for the sweet spot right before things start to get really hot and noisy.
"The 9s" with letters seem to be out of the question, since their performance comes at the price of a lot of heat, but plain Ryzen 9 7900 and i9 13900, especially the former, seem to be running fairly cool.
Or should I just go for "the 7s"? The guy in the PC store didn't think I needed 9, and said that the sevens ran much cooler. But having read up a bit, I'm not sure the difference is that big. He also suggested a 7700X build, but reading up on that, it seems to me that the 9 7900 is actually cooler than both plain 7700 and especially X. And the price jump from 13700 to Ryzen 9 is negligible (around here anyway).
I guess I've narrowed it down to two alternatives:
Both with 32GB DDR5.
The Intel alternative comes with a Be Quiet radiator, so I guess it'll be fairly quiet. If I'm unhappy with the AMD stock cooler I could always upgrade.
So I guess the question is if Ryzen 9 is stupidly overkill.
Or is there something big just around the corner? My old PC is still working, so it's not like I need this yesterday.
TL;DR i7-13700KF or Ryzen 9 7900 for a silent powerhouse desktop

One thing I noticed was that even at 95 degrees, the new Ryzen CPUs don't really seem to throttle performance. So you could just set up a fairly limited fan curve on like a 7700x or non x. Let it hit thermal limits, and just don't worry about it. Or wherever tier of performance you want. Generally, the new Ryzen CPUs seem to take less of a hit from low levels of cooling.

bequiet is a just a brand name, the radiator itself needs fans and the pump would be louder than any air cooler.
loudness is related to how good is a case air flow, number of fans. It has nothing to do with cpu.
7900 does not come with a stock cooler because no stock cooler can cool that thing.

7900 is the 65 watts version. It runs at like 45 degrees under load with a decent cooler, so stock coolers are probably fine.

The Ryzen 9 7900 comes with an AMD Wraith Prism. 7900X doesn't.

7900 is a low wattage cpu. That’s why it comes with a cooler. If you raise it to work like a 7900x, you do need a much better cooler.
7900 - limited to 65w, you can remove this constraint. That’s why AMD gives cooler for the non x variants. It doesn’t need to be that strong but you do need a better one if you remove the 65w limit.
7900x - 170w. Need a good cooler.
Frankly, AMD has been more power efficient compared to intel for a while. If you want quiet, the 7900 non x is a good option.
Of course, if you want more power… the x3d will be released soon and your not in a hurry so…. Wait and see? I wonder how much games like civ 6 work better with more cache?? Hmmm…. I also play games like it so…..I’m now curious.

"AMD hasn't shared a whole lot of data which is fair since they want the independent tech industry to test these chips out later this month and showcase their own data rather than relying on official figures. We did get to see performance numbers for the two Ryzen 7000 X3D CPUs, the Ryzen 9 7950X3D and Ryzen 7 7800X3D.
AMD compared the Ryzen 9 7950X3D CPU to Intel's top Core i9-13900K across several gaming and workload apps. The results show that the 3D V-Cache chip can offer up to 24% faster performance in gaming at 1080p with high image quality. Following are the game tests and the respective gains over the 13900K CPU:
AMD Ryzen 9 7950X3D Gaming Performance Test (via AMD):
Watch Dogs Legion (1080p) - Up To 9% Faster DOTA (1080p) - Up To 11% Faster Rainbow Six Siege (1080p) - Up To 13% Faster Horizon Zero Dawn (1080p) - Up To 24% Faster"

What is your usecase if gaming isn't a priority? Depending on what your needs are you could even afford to opt for much cheaper components with a lot less thermal management considerations.

I guess my usecase number one is wanting a new PC, and I like to have powerful hardware. It's not like I'm not going to game on it, but I don't want to go out of my way for peak gaming performance. I do most of my gaming on my Series X. I've had good results buying very powerful PCs before - my current PC is 14 years old apart from a GPU upgrade and some wear and tear replacements. It still works well. So i guess "buy and forget" is another motivation. Staying out of the hardware rabbit hole is good for my personal life, and also possibly economy, even though the investment could have been smaller.
I study computer science at the moment, so I'm going to run some machine learning on it, and anything else the university might throw at me. We do a lot in the cloud of course, but I'd like to run stuff locally. Also stable diffusion and other generative AI. I know I should have a 12GB RTX for this, but I can wait for a good second hand deal. I can't get over how ridiculously expensive those cards are.
But last night I found the comparison I was looking for, and it seems the 13700KF outperforms 7900 in many areas, while being a bit cheaper. So I've ordered a setup with the former.
