13600K or 5800X3D?

[SilentSierra]

What to choose? 13600K ou 5800X3D with 64GB DDR4 3200MHz RTX 3080 for HP Reverb G2 Rev 2 on DCS World 2.8+ Open Beta?

Almost same price, same performance in games, end of socket, DDR4, etc.

I keep saying it but if you go for an AMD CPU, Ryzen 3D, you will be better off bounding it with Cl14 RAM, preferably a 4 X 1 bank kit, simply because it is designed for low latency with on top the amount of cache giving it an edge under load.

The Ryzen controllers have a limit of 3200MHz with high street RAM and 3600MHz with B.die, that would be Cl4 RAM thanks to a wider range of timings offer by the B-die chips.

You can find those kits in 3200 or 3600MHz form, but better go for the 4 X 1 kits, rather than buying 2 2 X 1 which can cause issues, B-die are more expensive but thinking of it, you could go for a 64GB or 128GB Cl 16 kit and still have a bootleneck under load (4K) which mean that your CPU will throtle down and your system will be slower.

Here is the difference between my previous system and my current one: 5600X with 32GB Cl14 4 X 1 bank kit, both CPU (1080Ti) and GPU boosted (Ryzen Master and NVidia afterburner) vs Ryzen 7 5800X 3D 32GB Cl14 4 X 1 bank 3600MHz kit, same GPU no boost.

BOTH tested back to back at 4K 2 X MSAA on 3DMark Pro.

As you can see the difference is important even if the 5600X clocks marginaly faster, it just can't compete vs the 5800X 3D, it's mostly in the cache, the higher RAM frequency doesn't make much difference, they both used interleaving, their controllers were able to manage and spread the datas over 4 sticks improving the speed further.

More importantly, all the buses stays fully open under load, no bootleneck there, so if you ask me it is worth the investment even if some guys will always disagree, a gain of 18.91% at 4K is not negligible.

So at the end of the day it is up to you which amount of money you want to spend, you don't need 3600MHz, a 3200MHz B-die Cl14 kit would do you just as well, plus they can easily be O.Ced, they are designed for it, the 3600MHz are not, the CPU controller won't let you try higher frequencies.

Now, I can't talk about Intel, I don't have the experience for those CPU but those guys does.
