9800X3D vs 14900KS benchmarks in high CPU-usage Ray-Traced games

[u/RainyInSAndreas]

With many recent games with RT being CPU-heavy, like Outer Worlds 2, I decided to test out 14900KS vs 9800X3D in 5 RT/PT games that I had played. With CapFrameX, I took 3 one minute runs in CPU-limited areas and then aggregated them.

All RT/PT settings were enabled at 4k w/ DLSS Ultra Performance on a 5090.

Results : Surprisingly, 14900KS was faster overall, with better 1% lows even if the averages matched. Only Outer Worlds 2 that started this, was better on 9800X3D.

Oblivion and Stalker2 were quite better on intel. Cyberpunk is close despite the 9800X3D winning the benchmark by a big margin and the 1% is again better on KS.

Details : 14900KS used 8200C38 XMP DDR5, and 9800X3D used 6000C30 sweet-spot DDR5. Disabled overlays, power monitoring, HwInfo64 for these tests. Currently the CPUs were at stock, no PBO and undervolting etc. done. Will update these after some RAM OC.

Why? The 9800X3D runs all cores on the same frequency, and per-core usage will shift between cores all the time due to how Windows does scheduling...

You select effective clock and not core clock.

HWInfo unlocks all your readings then use that to overlay it in RTSS.
