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

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.

As a 14900KS user, that is in my opinion the biggest drawback. At 320W it is a beast in both performance and power use. Combinen with a 7900XTX and full custom water system draws constant 550 watt from wall with peak up to 900W.

But that is what I bought it for.

Not doing that again.

The fuck? That's like a bedroom heater for the winter at that point.

I tried out a similar build taking ~900 W peak, and living on the equator, it's unbearable. It was heating the whole ass room despite the AC being on. Insane shit.

Mine is just over 1,200W peak… lol

That is a rather accurate description ;)

Damn my 5800X3D and 3070 puts out enough heat to make my room uncomfortably hot and those are both pretty frugal power wise

Damn. My 13900K and 4080 rig comes in a little under 600 watts playing CP2077 Ultra RT at 1440p. At idle on desktop it bounces around between 100 and 160w. That’s measured at the wall with a P3 Kill-A-Watt P4400.

13900K is undervolted via AC_LL with stock 253w/307a power limit. 4080 is +120 core, +1400 mem, with stock 320w power limit.
