Gaming Performance 4K

On this page, we are going to see how gaming performance is affected between the CPUs at 4K, which is generally more GPU-dependent. We are using a fast NVIDIA GeForce RTX 3080 Ti Founders Edition Video card. We have chosen games that are mixed in being GPU dependent, and CPU dependent, all modern games.

Cyberpunk 2077

AMD Ryzen 7 5800x versus Ryzen 7 3700X Cyberpunk 2077 4K

As we might expect for this game, at 4K and “Ultra” settings it is completely GPU dependent. There is no difference in performance between the CPUs because even with the GeForce RTX 3080 Ti, it isn’t enough.

Watch Dogs Legion

AMD Ryzen 7 5800x versus Ryzen 7 3700X Watch Dogs Legion 4K

The same is true for Watch Dogs Legion at 4K, performance is identical across the CPUs as the game is GPU-dependent at 4K and “Ultra” settings.

Microsoft Flight Simulator 2020

AMD Ryzen 7 5800x versus Ryzen 7 3700X Microsoft Flight Simulator 2020 4K

Even Microsoft Flight Simulator 2020, which showed a big difference at 1080p, is now GPU-dependent at 4K and performance is the same between the CPUs.

Red Dead Redemption 2

AMD Ryzen 7 5800x versus Ryzen 7 3700X Red Dead Redemption 2 4K

The trend continues in Red Dead Redemption 2 at 4K, we are GPU-dependent, not CPU.

Crysis Remastered

AMD Ryzen 7 5800x versus Ryzen 7 3700X Crysis Remastered 4K

Crysis Remastered is the only game here where the CPU still matters even at 4K. We do see the Ryzen 7 5800X providing 8% greater performance at 4K with the same video card. This makes a pretty significant difference playing this game at 4K, smoothing out performance above 60FPS in the really intense situations.

Metro Exodus Enhanced

AMD Ryzen 7 5800x versus Ryzen 7 3700X Metro Exodus Enhanced 4K

Metro Exodus Enhanced is completely GPU-bottlenecked at 4K.

  1. I built 4 systems for people using the 3700X. I was really hoping there would be a 5700X. Or they could drop the price on the 5800X, that would work too. 3700X and 5800X are both good CPUs, but the superiority of Zen 3 really shines through. I wasn’t expecting an article like this, nice surprise, thanks Brent.
  2. I’m on a 5800x for my gaming PC. Very happy. I came from a 3800x. Which seems silly, but who cares. HAHA
  3. Cool to see a side by side between the two. I had considered upgrading to a 5800X, but think I’ll hold on to my 3700X for a couple more years. At 1440P the gaming difference is probably 2-5%, so it really doesn’t make sense.

    Curious, why was PBO not enabled for the 3700X?

  4. So basically for gaming at ultra / 4K it is worthless to upgrade, thanks for that, now my itch to replace my 3700x is completely gone.
  5. It was a very nice incremental upgrade. The biggest benefits IMO were better RAM compatibility / higher RAM clocks, but the higher power envelope and clock speeds were nice.

    I wouldn’t see it as a necessary upgrading coming from Zen2+ either, but if you were on anything older (Haswell, for me), it was a very nice boost.

  6. I made the change from the 3700X to the 5800X and have enjoyed every single bit of improvements so far.
  7. So basically for gaming at ultra / 4K it is worthless to upgrade, thanks for that, now my itch to replace my 3700x is completely gone.

    Yeah.. That’s why I left my 3700X at home, and went with the upgrade for the work machine. I am noticing a good performance boost for my work applications for sure.
