I've reassembled my X99 system with my 3090, and installed a fresh copy of Windows 11 22H2 on it. It was a last-minute decision so I did not run benchmarks on the 5950X before I packed it (it will be listed and hopefully sold soon), but I have run a few benchmarks on this system and I am open to requests as long as it is something I happen to own:
Specs (GPU is set to run at 1830 MHz flatlined with +800 on memory, Vulkan developer driver 527.86):
Before anything, I must stress that Windows 11 22H2 runs horrible on this processor/system, unlike the initial 21H2 release. It stutters and lags a
LOT. There may be something there about Microsoft withdrawing formal support and blocking installs for earlier generation computers, because the experience is nothing short of rotten. However, it benchmarks fine and games behave normally as far as I can tell.
In Endwalker, the second scene where it shows a town and a library dips to the low teens in frame rate, something which the benchmark software fails to report.
Final Fantasy XV doesn't suffer from the same extreme slowdowns in specific scenes, but the frame rate average is noticeably lower than on a PC with a faster CPU and the same graphics card:
The same applies to Horizon, which was surprisingly the most playable of the games I've tested (DLSS and FSR were kept off):
Red Dead Redemption 2 was tested with the settings slider all the way towards Favor Quality, with DLSS and FSR disabled and no other custom settings. It was also pretty playable, though slowdowns to the 30s were common during scene switches (with a relatively fast recovery time).
The low clock speeds of my processor are somewhat mitigated by its very large L3 cache and dual-IMC design, but it shows well the problem with using an older/slower CPU arch: the IPC just doesn't hold. This one benchmarks very close to what an FX-8350 usually does in single thread, the result is that whenever engines try to stream assets, you will always be experiencing a brief pause or blurry textures until things settle and the game continues to render as normal.

Truly classic processor!
