Gaming Performance: 4K
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:
- DDR4-3200
Civilization VI
Final Fantasy 14
Final Fantasy 15
World of Tanks
Borderlands 3
Far Cry 5
Gears Tactics
Grand Theft Auto V
Strange Brigade (DirectX 12)
Strange Brigade (Vulkan)
Typically when gaming at 4K resolutions, most games at these settings are GPU dependent with the CPU not usually having as much influence as a graphics card. In some of the games such as Final Fantasy 14, Grand Theft Auto V, and Strange Brigade, the additional L3 cache on the Ryzen 7 5800X3D did make a noticeable difference to performance.
In Strange Brigade, the Ryzen 7 5800X3D was top when testing with the Vulkan API, but in Direct X 12, the results were reversed, with the V-Cache making no difference in this scenario. Even in Far Cry 5 at 4K resolutions, the Intel 12th Gen Core did markedly better, which wasn't the case in our 720p and 1080p testing.

Great 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 - link
It 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 - link

Also impressive is how much the cache improves WinRAR performance. Going from last to 2nd place - with a lower clock speednandnandnand - Thursday, June 30, 2022 - link
Compared 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 - link
WinRAR has always been extremely dependent on memory performance. That a huge cache benefits it isn't a big surprise.emn13 - Monday, July 11, 2022 - link
Sure, 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.

Just 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.

I’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.
