Gaming Performance: 4K
Last, we have our 4K gaming results.
We are using DDR5 memory on the Ryzen 7 78000X3D and the other Ryzen 7000 series we've tested. This also includes Intel's 13th and 12th Gen processors. We tested the aforementioned platforms with the following settings:
- DDR5-5600B CL46 - Intel 13th Gen
- DDR5-5200 CL44 - Ryzen 7000
- DDR5-4800 (B) CL40 - Intel 12th Gen
All other CPUs such as Ryzen 5000 and 3000 were tested at the relevant JEDEC settings as per the processor's individual memory support with DDR4.
Civilization VI
World of Tanks
Borderlands 3
Grand Theft Auto V
Red Dead Redemption 2
F1 2022
Hitman 3
Total War: Warhammer 3
At resolutions of 4K and above, graphics card performance has a bigger impact on overall performance than the processor, regardless of the number of CPU cores or their speed. Although the Ryzen 7 7800X3D still performs well at these resolutions, it doesn't have as much of an advantage as it does at lower resolutions. Our testing shows that most of the CPUs we've tested perform similarly when paired with a high-end graphics card like the AMD Radeon RX 6950 XT. Even in games where lower resolutions benefit from the additional L3 cache, it doesn't have as significant an impact on performance at 4K.
In summary, while the Ryzen 7 7800X3D still performs well at 4K resolutions, it doesn't have as much of an advantage as it does at lower resolutions, and the graphics card has a bigger impact on overall performance. Our testing suggests that a premium graphics card is essential for achieving good framerates at 4K, regardless of your CPU.

No one buying an x3d processor cares more about ECC memory but I'm guessing you enable that setting for your graphics cards?WhatYaWant - Wednesday, April 5, 2023 - link
Great review, just missing the 7700x omissionGavin Bonshor - Wednesday, April 5, 2023 - link
Yeah, unfortunately, AMD didn't sample us that chip. It is definitely one we will be requesting, though.GreenReaper - Wednesday, April 12, 2023 - link
Should request it as a business expense from Future. Are they being stingy over a $347.99 purchase that acts as a tax deduction either immediately via section 179 (USA)/AIA (UK) or depreciated over five years, when they netted £122.2 million in 2022?Makaveli - Wednesday, April 5, 2023 - link
Great review and thanks for adding the 5800X3D I picked up one last weekend.Marxman - Wednesday, April 5, 2023 - link
Is there a reason you're pairing the fastest CPUs on the market with a last-gen GPU and the slowest DDR5 I've ever seen? This test setup is abysmal, quite frankly.Ryan Smith - Wednesday, April 5, 2023 - link
The current CPU testbed was setup for the launch of the Ryzen 7000 series back in September. At the time that was put together, the RX 6950 XT was one of the fastest video cards on the market. We typically only cycle our workbench once per CPU generation, as it requires that we throw out all of our work each time.As for the memory we used, that is following a long-standing testing policy with the site. We test CPUs with the fastest memory they officially support. Overclocked memory a) Voids your processor warranty, and b) Isn't guaranteed - which is to say that you can't RMA a chip because it doesn't overclock to some specified frequency.
We've had discussions with AMD and Intel on the matter before. If they change these two policies, we'd be happy to update our testing policies to match. Otherwise, our preference is to stick to settings that won't break your processor, and represent a level of performance that all chips will attain, rather than a level of performance that a subset of chips may attain.

Seems fair. They should be willing to warranty ddr5-6000 if they want you to test with it.TMU - Wednesday, April 5, 2023 - link
Thanks for the review. I got my eyes on that 13600k sealed the deal for me.achinhorn - Wednesday, April 5, 2023 - link
"During testing, it was evident that Ryzen 7 7800X3D provides significant advantages in gaming compared to chips without 3D V-Cache"Define significant, and what evidence makes it evident? Give us some statistics and relevant titles that show this clearly in that same paragraph. This and the 7950X3D review with these claims read more like sales documents to me, personally. None of the performance-related graphs on the conclusion page with the exception of Hitman 3 seem to highlight these significant advantages (which is a discussion of 300+ fps to more than 300 fps... that won't even be noticeable)
There are many things about this chip that I like, but from a raw performance stand point, the advantages seem marginal or not at all with the exception of one or two titles. If anything, the real advantage here is the performance:cost ratio. Am I wrong? What did I miss?
