Question Which CPU : Intel 13900K(S?) or AMD 7950x3d

[rabbit1qaz]

Hi, im changing my pc parts and i was wonder what would be better in case of VAM and further with VAM2? Vam is one threaded so what will be better ? 6.0Ghz of 13900kS or 5.7 but with big cache of AMD ?

GPU is 4090.

AMD cos u can upgrade the cpu later. Intel is last cpu for its mainboards. Performance is comparable.

May i ask if your message is based on experience with those 2 CPUS and VAM? Or knowing strong and weak sites of VAM technology its theoretical opinion? couse as i saw comparisons in certain games there are big diffrence in FPS for Intel in some and amd for another (diff like 40FPS). So i ask for this hmmm "game" or rather entertainment environment, not overall.

The problem is: we dont have any benchmarks with a 7950X3D in the benchmarks thread yet. So no one can really say what is better right now for VaM.

Overall the 13900K is a good investment with DDR4 and a regular MB, but power hungy and not futureproof.

7950X3D is very power efficient and futureproof, but expensive with MB plus DDR5. Definitely slower in single thread.

But still we dont know how the bigger cache performs with VaM.

side note: On 7950X3D only CCD without extra v-cache can hit that 5.7 boost,
other one with extra cache is clocked lower (at ~5.25 reported by AnandTech and TechPowerUp).

Also it would be interesting to see how scheduler and VaM are handling that part.
So far we don't know... nobody posted any benchmarks. ?‍

We more or less know how 5800X3D permormed in VaM (compared to 11/12th gen).
Personally I am more interested in 7800X3D (to avoid CCD switching), sadly it's postponed to april.

How were the results 5800X3D vs. 12700K and/or 13700K, do you know? Same GPU?

I have hard time finding 12700k/13700k results with similar systems or with 3080 (Ti)...besides your 13700k results.

After quick search @1080p and with 32GB ram:
(Obviously not identical systems)

with 3080:

Maybe I missed some results (not everyone adds specs info, so search doesn't work).
We have like 4-5 different 5800X3D results out there and one of them is with Quadro RTX 6000.
Others are with 4090 and RX 6800 XT (If you can find 4090/6800 XT counter parts, maybe you can use them).
