    兄弟们有人用过这个没有,AMD的EPYC 7601。最近才发现A厂官方竟然拿7601做CFD测试,最多的网格数量3个亿,真有钱。这个处理器有这么暴殄天物么?下图:

    另外有网友用OpenFOAM做的测试,也是AMD EPYC系列的,型号略低

    国外玩家评论:

    A quite compelling comeback for AMD in terms of CFD performance. Their new Epyc lineup delivers exactly what Intel has only increased incrementally over the past few years: memory bandwidth.
    总结:牙膏厂几年一直在慢悠悠的增加内存带宽,AMD一下子就干翻!

    Although the AMD system in this benchmark ran slower DDR4-2133 instead of the maximum supported 2666MT/s, it beats the Intel-system even in terms of per-core performance. Using all its cores, it pulls ahead of Intel by up to 63%.
    总结:提升63%!

    Which brings us to the costs: Epyc 7301 CPUs cost ~920€ - if they are available which is still a problem. For that kind of money all Intel has to offer are Xeon Silver with 12 cores and support for DDR4-2400. So when you are on a limited budget for a CFD workstation or need cost-efficient cluster nodes, you should consider AMD.

    They are back!

    AMD要回来了!!!

    有人买过这个处理器没?

    AMD 感觉就像联通,其实在某些方面有很大的优势,常常被低估。

    @netbuger A厂发挥不稳,神经刀一样。。
    @东岳 再牛逼的u,也得考虑功耗和散热。。
    amd,全线程跑起来,估计冬天家里不用开暖气了吧 😂 😂

    我现在桌子底下就有个CFD用的机器,每次伸手下去都感觉热乎乎
