咨询至强Gold 5220和6133

aikeyin

我的服务器CPU是2颗Xeon 8171m（TDP为205 W，使用的EP2C621D12WS主板），在家里使用总感觉功耗比较大，看到网上有Gold 6133（150 W）和5220（125 W），都是低功耗的CPU，但是不知道这俩U的性能相比于8171m怎么样？此外，这俩U之间对比，哪个性能更好些呢？比如运行cp2k，qe，orca时的全核满载频率，哪个更高，用时更短。最后，如果买2颗Gold 5220可以继续使用EP2C621D12WS主板吗（5220应该是Cascade lake，不是Skylake）？希望大佬能给点儿指导，感谢。

上7R13比这两货好多了

感谢您的指导，查了下7R13，TDP、核心数量和频率确实都好

My guess is that the 8171M will significantly outperform the 6133 and 5220.

Thank you very much for your guidance !

同代cpu的基本上看tdp就知道了，6133基本上打不过8171。5220多核能力跟8171大致相当，主板看接口应该是可以 ...

好的，谢谢您

From my experience with Cascade lake and Ice lake Xeons, I found these wikipedia pages (Cascade lake, and Skylake) to be a reliable source of specs, including all-core turbo frequencies. You'd expect to get a modest IPC uplift upon going from Skylake to Cascade lake, but not enough to offset the core-count and all-core turbo boost advantage that the 8171M has.

I find Asrock Rack boards to have very good compatibility, even with off-roadmap Xeon CPUs. Nonetheless, here's the confirmed CPU compatibility list. The 5220 is listed on there (make sure you upgrade the BIOS if necessary), but I also expect the 6133 to work just fine (if not, rolling back to a previous BIOS might be necessary).

If minimising energy consumption and heat production is really important to you, then upgrading might make sense. There will likely be some performance drop, but it won't completely stop you from doing any of your typical workflows, they'll just take slightly longer.

Another consideration that if your workflows are memory-bound, then Cascade lake supports higher memory frequencies (up to 2933 MHz). Also, this generation supports Optane persistent memory, which can be a very cost effective way of increasing memory capacity (very useful if latency is not a bottleneck). Alternatively, Optane can be used as very low-latency and high write-endurance scratch storage, which is certainly useful for DFT calculations. 128GB DIMMs are only about 500-750 RMB currently, but you'll probably need to change your motherboard as I don't think this one is compatible.

同代cpu的基本上看tdp就知道了，6133基本上打不过8171。5220多核能力跟8171大致相当，主板看接口应该是可以用的，就是怕你的主板有限制，有的cpu用不了，这个要了解清楚
