Gaming Performance: 720p and Lower
All of our game testing results, including other resolutions, can be found in our benchmark database: www.anandtech.com/bench. All gaming tests were with an RTX 2080 Ti.
For our gaming tests in this review, we re-benched the Ryzen 7 5800X processor to compare it directly against the newer Ryzen 7 5800X3D on Windows 11. All previous Ryzen 5000 processor were tested on Windows 10, while all of our Intel Alder Lake (12th Gen Core Series) testing was done on Windows 11.
We are using DDR4 memory at the following settings:
Final Fantasy 14
Final Fantasy 15
World of Tanks
Far Cry 5
Grand Theft Auto V
Red Dead Redemption 2
Strange Brigade (DirectX 12)
Strange Brigade (Vulcan)
At 720p resolutions and lower, we are significantly (and intentionally) CPU limited. All of which gives the Ryzen 7 5800X3D and its 3D-Vache the chance to shine.
The addition of 3D V-Cache to one of AMD's mid-range chips makes the Ryzen 7 5800X3D a much more potent option in gaming, with much better performance consistently than the Ryzen 7 5800X. This is very much a best-case scenario for AMD, and as we'll see, won't be as applicable to more real-world results (where being GPU limited is more common). But it underscores why AMD is positioning the chip as a gaming chip: because many of these workloads do benefit from the extra cache (when they aren't being held-back elsewhere).
In any case, the 5800X3D compares favorably to its more direct competition, the Intel Core i9-12900K and Ryzen 9 5950X (which are both more expensive options). In AMD partnered titles, the Ryzen 7 5800X3D does extremely well.

nandnandnand - Thursday, June 30, 2022 - linkGreat results for the 5800X3D in Dwarf Fortress and Factorio. Clearly it does not have enough cache for the World Gen 257x257 test.
dorion - Thursday, June 30, 2022 - linkIt shows the exceptional predictors in Intel's architecture, they don't have 96MB of L3 cache either(duh) and yet they whip that world generator. Wonder what odd coding of Tarn's the CPUs are butting against. And exceptional amount of civilizations and monsters to simulate for 550 years in the 257x257 world?
AndreaSussman - Sunday, July 31, 2022 - linkHello
Samus - Thursday, June 30, 2022 - linkAlso impressive is how much the cache improves WinRAR performance. Going from last to 2nd place - with a lower clock speed
nandnandnand - Thursday, June 30, 2022 - linkCompared to some of the earliest reviews like Tom's, this one found more productivity/code scenarios where the extra cache helps it edge out over the 5800X, despite the lower clock speed. Obviously there are niches where the 5800X3D will do really well, like the workloads that Milan-X can boost by >50%. You won't usually see them all in one review.
DanNeely - Sunday, July 3, 2022 - linkWinRAR has always been extremely dependent on memory performance. That a huge cache benefits it isn't a big surprise.
emn13 - Monday, July 11, 2022 - linkSure, but it's more than just memory performance that's an issue here: in very abstract principle compressors need to find correlation across broad swaths of memory. It's actually not at all obvious whether that's cache-friendly; and indeed in 7-zip it appears not to be.
After all, if your compression context significantly exceeds the L3 cache, then that cache will largely be useless. Conversely, if your window (almost) fits within the smaller L3-cache, then increasing its size is likely largely useless.
The fact that this helps WinRAR but not 7-zip is not obvious. Given the compression ratio differences, I'm going to assume that 7-zip is using more context, and thus can't benefit from "just" 96MB of cache. And perhaps that WinRAR at higher settings (if it has any?) wouldn't either.
That does make me curious how the 3d-vcache impacts the more high-throughput compressors such as zstd or even lz4 perhaps.
brucethemoose - Friday, July 1, 2022 - linkJust wanna say I am ecstatic over the DF/Factorio tests. Stuff like that is where I'm most critically CPU bottlenecked these days, as opposed to CPU Blender or Battlefield at 720p.
I'd like to suggest Minecraft chunk generation as another test (though its a bit tricky to set up). Expansive strategy/sim games like Starsector, Rimworld, Stellaris and such would also be great to test, but I don't think they're fully automatable.
29a - Tuesday, July 5, 2022 - linkI’d also be interested in a Stellaris benchmark.
ballsystemlord - Thursday, June 30, 2022 - link@Gavin , is it just me, or do you have two sets of identical WoT Benchmarks at 1080p? BTW: I'm looking at the print view.
