3950X slightly faster than 10900K at 4K with 5700X: PCIe4?

[humbug]

Hardware Unboxed are thinking about using the 3950X instead of the 10900K for RTX 3000 series testing, because the Ryzen CPU's have PCIe4, and in a poll 83% voted to use the 3950X.
He also acknowledged there was little interest in their Z490 and Intel 10K series reviews, he's of the view most people now run Ryzen and wants to better represent users.

So he did some testing, there was not a huge difference between the 10900K and 3950X at 1080P with a 2080TI, mostly under 10% while at 1440P there was nothing between them.

What is interesting the higher the resolution on the 5700XT the better the 3950X did, at 4K the 3950X was never slower but in most instances slightly faster than the 10900K, small margins but Steve said these differences are consistently repeatable in every run.

From what I recall, only the 5500 XT (and only the 4GB ones) had shown substantial differences with PCI-E 4 versus 3, but unlike the 5700 it's limited to 8 lanes on the card. Would be interesting if this applies to the 5700 XT too, though going forwards, for how long can it push the pixels fast enough to be playable at 4K?

Now that is how I want to see a CPU tested, none of this useless 720/1080P medium setting crap. Good work Hardware Unboxed.

Thing is there decision to use an intel or amd cpu will answer itself in a few months anyway, i dont think intel will hold the gaming (or 1080p gaming) crown when Zen3 appears.

The 5700XT is a pretty good pixel pusher, i play Star Citizen at 3200x1800P Very High, it can't quite manage 3840X2160P, its 8GB choke.

It's interesting that a 3950X and 5700XT yields better results.

Really excited for amd Ryzen next version coming.
Upgrades are fun

The problem for PC's is PCI-E 4.0 is still tragically slow compared to what consoles have in terms of interconnects, so next gen ports could be crippled even by PCI-E 4.0. PCI-E 6.0 looks a lot more respectable compared to what modern consoles have.

 

[humbug]

How much bandwidth will the RTX 3000 GPU's need for Ray Tracing?

 

[CuriousTomCat]

A test with PCI-E 4.0 mode off would be interesting (if such a setting exists) so we can see if that's the reason it won.

Thou speaketh good sense sir.

Amen my brother.

Isn't pcie4 5gbps and ps5 5.5?

Or, the data shows AMD drivers are truly multi-threaded while Nvidia drivers are still single-thread dependent.

These jokers still using 3200mhz mem rather than 3600?

Horizon zero dawn is an anomaly as it seems to really hammer the PCI-E bus when it shouldn't need to, that game seems to be treating the PC like the console unified memory architecture where all RAM/VRAM is GDDR5. So I would expect PCI-E 4.0 to gain a slight advantage here where it's thrashing the PCI-E bus.
