Re: Best cpu for my EVGA 3090.

After many hours of tweaking and testing all I can say is a bit disappointing. Overall the ryzen is way better than my old 8700k@5ghz. But for gaming...I know playing at 4k there won't be diference but I still get around 4-5fps in almost every game with a RTX 3090.
The "fps lows" are a bit better with the ryzen processor. I tweaked the rams a lot as well (3800mhz cl14 and Infinity fabric 1900mhz).
Also overclocking the processor to all cores are 4.8ghz or boost single core to 5.05ghz doesn't make difference in the gaming.
I have been trying at least to replicate the results of my 8700k@5ghz with no luck. Instead of being a few fps lower I expected to be with the same or a few fps up.
So I'm thinking to get a z590 with a 11900k. That should give me scores like the 8700k or a bit more.

I think Ryzen 5900x is the best choice if you can get one. 5900x rather than 5800x is because 5900x has higher single core boost clock plus its 12 cores is future proof, plus 5900x duo ccd double the L3 cache speed. 10900k is mediocre since Intel is releasing 11th gen.

That's what i thought as well but in real life gaming at 4k with my 8700k@5ghz and z370-e is slightly better. 3-4fps diference in most games. Shouldn't be like this but I have tried everything. Except gaming a 5900x is much better than a 8700k@5ghz. I only game with my pc so not the best in that regard.

Well, I guess it is what it is. Maybe the titles you are playing just not favor AMD CPUs. There is no right and wrong when choosing CPU, just pick the one that best suits you need.

Intel is just better for pure gaming in 4k. Your best bet is indeed 10900k or 11900k. These guys that keep saying the oft-repeated fallacy that "it doesnt matter in 4k) arent holding rtx 3090 and gaming in 4k/120, I promise you that or they'd know better. High refresh rate gaming needs fast ram and fast 8core + processors, and low latency. As for which to pick 10900k or 11900k- now THAT is a compelling question. 20% more IPC or 20% more cores. (assuming both all-core at 5.3Ghz) Im thinking 11900k because more games are likely to take advantage of 8 cores vs 10 cores, and the PCIe 4.0 will give around 3-5% perf on my 3090, as well as enable twice as fast NVMe drives. Im here on this 10700k and Im ready for Rocket Lake to drop already.

During the last weeks i tried again another amd build. This time x570 crosshair hero and a 5800x (before I tried 5900x). The results were again the same at 4k comparing to the 5900x and a bit worst than my old 8700k@5ghz. So I decided for intel z590 MAXIMUS HERO XIII and 10900k. Performance increased in most of the games. Not much but specially the lows are higher which is good for smoother Gameplay. Dual Rank Ram makes no difference in 4k. I tested well and tweaked timings. I'll get the 11900k because the IPC uplift, 8 cores are more suitable for most of games and also for the direct PCIe lines from the ssd to the CPU (latency).

The bottleneck Calculator at https://pc-builds.com/calculator/ can help pic CPUs for your existing motherboard or a board and CPU you want to go to. Keep in mind that some motherboards are getting BIOS updates for Re-Size BAR support which can help with performance so updating the motherboard to the latest one and enabling it as well as Above 4G Decoding and disabling CSM in the BIOS can help on its own. In Windows go to Settings -> System -> Display -> Graphics Settings and enable Hardware-accelerated GPU Scheduling as it was added a little bit ago.

The thing is that I bought and tried the two AMD builds because of reviews from "experts". After this I won't trust anymore many websites because yes AMD destroyed Intel overall by a big margin with 5900x and 5950x, except gaming. At least im 4k. Even my old 8700k@5ghz does a slight better that the two AMD builds. Maybe memory latency or something because results in 3d game and benchmarks were consistent. I'm not intel fan at all. Only looking for best gaming experience. There's nothing better than testing yourself. ;)

I currently have a 9700k at 5.2ghz and a 3090xc3 ultra. Dont see much of a bottleneck on that, nor seems many games would benefit from more cores/threads (that i play, i mainly play rts and arma which favor single core) and some youtube vids have comparisons that show the minor difference. The new amd stuff looks solid, especially the 5800x, but i mainly do civil CAD and gaming and dont see most of the benefits amd offers. Still holding out for the new 14+^2 Intel is heading out with, but so far my 9700k is still a top level gaming cpu. I think OP is fine with his 8700k at that freq. Wouldnt let me link the YT vid, but theres a vid that shows the diff between a 8700k and a 9900k with a 3090 is rather minimal, however it doesnt show clock speeds. " RTX 3090 + i7-6700K vs i7-7700K vs i7-8700K vs i9-9900K test in games - 1080p - 1440p - 4K"

Yep the 9700k is still a great CPU for gaming.
With the 10900k now I have almost the same performance than with the 8700k@5ghz. The mayor difference is in the lows which are better now.
With the 11900k i expect the same but with direct access from the ssd to the CPU and more future proof with PCIe 4.0.
