    Which projects use AVX-512?

    Which projects use AVX-512? I think it may be only one or two projects, but I can't recall any details.

    I could swear we talked about this in the past, but I can't find anything using search. I tried searching on both "AVX-512" and "AVX 512". No results at all. Maybe search broke?

    The new Acoustics opti apps have an AVX512 version https://github.com/sirzooro/Acoustic...es/tag/opti1.0

    Thanks! Looking at the message board thread, there is not much improvement of AVX-512 over AVX2. In this case, it probably better just to have a couple more cores running AVX2.

    Code:
    Original-Linux    51,988
    Original-Windows  46,707
    SSE2              30,681
    SSE4.1            28,680
    AVX               24,659
    AVX2              23,882
    AVX512            21,569

    I'd take 10% anytime

    Agreed, all things being equal.

    But I was considering a 6 core Skylake-X i7-7800X with AVX-512 vs. an 8 core i9-9900K Coffee Lake with AVX2. I think the greater number of cores with AVX2 will out-perform the lesser number of cores with AVX-512. At least with this particular project. Am I wrong?

    Get a i9-9900X and you'll get more cores plus avx512

    Heh! Would love to, but a bit out of my budget...

    Well crap. Now that I am looking, I see the i9-9820X is on sale for $850. Same number of cores as the i9-9900X, but a slightly slower clock, and a bit less L3. The clock speed I think I can make up with OC. Will any of the projects really take advantage of more L3?

    The only one I specifically know that relies on the amount of L3 is MIPs on WCG. The project scientist posted last year that you shouldn't run more than 2 MIPs at the same time because efficiency goes to hell in a hand basket on most CPUs. He gave a formula of L3/???? that would tell you how many you can run on a given host without paying a huge penalty.

    Rake is also can use avx-512 I believe. Same dude wrote the app for Acoustics.
