The Ryzen 7 5800X3D has been a huge hit in the flight sim community since it launched earlier this year, owing entirely to its massive cache.[0]
Flight sims (especially DCS) tend to be built on archaic engines that rely heavily on non-parallel workloads, so the stacked cache approach can yield some crazy performance gains. I'm excited for the upcoming Zen 4 version of their X3D part.

- rl3 4y agoTurns out there's enterprise parts with 3D V-Cache as well.[0][1] 768MB (!) of L3 cache. Looks like it's only Azure for the time being. Couldn't find those parts on AWS or GCP. Although, AMD is using their own processors via GCP to.. design their own processors.[2] However, it doesn't seem like they're using 3D V-Cache parts there. Exciting times in any case. There's a lot of workloads that stand to benefit from these new cache architectures.
