    I can't say I'm too surprised Linux takes better advantage of the cache for productivity, but why doesn't it for games?
    I think it is just the type of games and applications being used. For games, most Windows games are larger and more complex and need a larger amount of space in the cache. You only see increases in performance where core logic to games is too big to fit in a traditional L3 cache and has to be fetched from memory. As for applications, most publications didn't really test any specialized deep learning or HPC applications due to the audience. Linux is just much bigger than Windows in those spaces.

    So we see how much V- cache add
    as 5800 and 5800X3D has different frequency
    There is a short video in Youtube on how to OC this to 4.8 Ghz and when benchmarked(on Windows) it's as fast as the 5800X on productivity apps that don't take advantage of 3D V-Cache but it gains pretty good performance on apps that do

    or downclock 5800X

    I must say I'm impressed with the 5800X3D. It can easily beat the 12900K in gaming, which is exactly what AMD claimed, while drawing less power. It can be a drop-in replacement for almost any AM4 board and it isn't as RAM dependant as other SKUs are (mainly because of its big pool of L3 cache), although it's a little pricy, but it's a top-of-the-line CPU, anyway.

    I don't think we have ever seen such a versatile platform. AM4 really delivered!

    I'd be interested to see some game benchmarks at 1280x720 to reduce the chance of any GPU bottlenecks, and maybe some benchmarks for games that show a big jump in performance in Windows, like Battlefield V (seems like it should work with Proton). For what it's worth, the 17.1% improvement you measured for Shadow of the Tomb Raider at 1920x1080 (High) is a lot better than this Windows benchmark that saw only a 0.4% difference (at Ultra, however).

    Zstd as well. Like Michael points out in the article, that probably had good benefits for file systems using Zstd for compression. I wonder if LZ4, XZ, and other codecs get performance improvements as well.

    And now do a 16 core 192 mb cache 5999x - am4 can handle it! Even with dual mem channels only, this thing will be a beast for hpc - a 1000$ seems a fair price.

    Nice article. The only info I’d be interested in is how it compares to the 5900x as it has been recently selling for $400us or less which is less than the 5800x3d. Definitely will be exciting to see if zen4 does carry a large cache like this and how much it will benefit. Obviously their larger market is windows for consumer tier sales and those most common workloads may not benefit as much as on linux or may be niche. Right now it seems like a trade off with clock speed, though they are maybe being overly cautious.
