Gaming Performance

Now we come to the interesting testing we are sure you all can’t wait for, we were also anxious to get to this part and see how it all ends up for gaming performance. In order to test this properly, really get a good feel for it, and cover all the bases for the big picture, we decided to test 1080p, 1440p, and 4K resolutions, all three resolutions to see from top to bottom how these CPUs affect performance games. For testing, we are using an NVIDIA GeForce RTX 3080 Ti Founders Edition video card. Since we are testing all 3 resolutions, it’ll be a good mix to see where the CPU matters and where it doesn’t.

Dying Light 2

In Dying Light 2 we are running the game at the highest graphics settings but without Ray Tracing. We are running in DX12 with Async Compute, and we use a custom manual run-through.

The performance results are very close in Dying Light 2 between both CPUs. If you want to say the Ryzen 7 5800X3D is faster, you can say that it technically is, but only by the smallest of margins. There aren’t any large or noticeable performance differences here at all. At 1080p is the largest difference, where the Ryzen 7 5800X3D is just 1% faster than the Ryzen 7 5800X. The results only get smaller from there, with 1440p and 4K being nearly identical, and within the margin of error for a manual run-through. In this game, it doesn’t matter which CPU you use, the performance will be the same.

Cyberpunk 2077

In Cyberpunk 2077 we are running at “Ultra” settings at each of the three resolutions and we utilize a custom manual run-through. This game shows a little bit of a bigger difference than Dying Light 2, but only at 1080p. Here, at 1080p the Ryzen 7 5800X3D is 4% faster than the Ryzen 7 5800X. While yes this is faster, 4% is overall a small amount, and at the performance, we are playing at above well above 100FPS it doesn’t really matter, you cannot tell the difference. Once we get to 1440p and 4K performance is the same between the CPUs, there is no difference in performance.

Forza Horizon 5

In Forza Horizon 5 we are running the game at the custom highest possible in-game settings with FXAA. We see only a 1FPS difference at 1080p between the CPUs, and no difference at all at 1440p or 4K. This game performs exactly the same between both CPUs.

Far Cry 6

Finally, this is the first game in our testing suite where we do see a big, and we mean big, difference between both CPUs at 1080p and 1440p. At 4K, not at all, but at 1080p and 1440p yes. The Ryzen 7 5800X3D is much faster than the Ryzen 7 5800X at 1080p, 28% faster to be exact. That’s pretty massive. In addition, at 1440p the Ryzen 7 5800X3D is 8% faster, not as much as 1080p, but still an improvement. The reason for this is quite simple, this game is CPU limited, and it really shows at 1080p on a video card like the RTX 3080 Ti.

The new Ryzen 7 5800X3D with its 3D V-Cache is just what this game needed at 1080p to overcome that CPU bottleneck. That’s why you see a tight grouping between 1080p and 1440p on the Ryzen 7 5800X. Yet, on the 5800X3D they are able to separate at those two resolutions, thanks to the new L3 3D Cache. It’s pretty darn amazing right there, but its usefulness drops off quickly as the resolution increases.

Microsoft Flight Sim 2020 GOTY Edition

Microsoft Flight Simulator 2020 Game of the Year Edition is another game that greatly, and we mean greatly, improves with the higher capacity L3 Cache on the Ryzen 7 5800X3D. In this game, it even helped at 4K! Right across the board, the 5800X3D is simply the better CPU for this game. At 1080p it’s 21% faster, at 1440p it’s 24% faster and at 4K it’s 9% faster than the 5800X. We see the 5800X is bottlenecking this game pretty hard, but the 5800X3D allows it to come out of its shell on the RTX 3080 Ti. Though we are still even seeing CPU bottlenecking at 1080p, because 1440p is beating 1080p performance, this shows that this game will benefit from even faster CPUs to really make that 1080p come out where it needs to.

Crysis Remastered

AMD Ryzen 7 5800X3D Crysis Remastered Graph

Crysis Remastered is another game where it can be CPU bottlenecked, and we find the Ryzen 7 5800X3D to provide a benefit at 1080p and 1440p, but not 4K. At 1080p the 5800X3D is 14% faster than the 5800X and at 1440p it’s 3% faster.
