We were told that the AMD EPYC 7401P may be negligibly faster due to having the dual socket capable circuitry disabled and therefore ever so slightly more power available for the rest of the package.
We validated the assumption with AMD that the EPYC 7401P and EPYC 7401 should be identical or nearly in terms of performance. We are using the AMD EPYC 7401 for our benchmark numbers today. These discussions are informed by running 6kW of systems constantly for months across a variety of workloads, including many we do not publish on STH. During this review, we will be discussing comparisons between different options. This review is part of a massive project to deliver a complete set of results for STH readers, our data subscribers and for companies we are advising. We have also completed work with every AMD EPYC performance variant from the EPYC 7251 to the EPYC 7601. Here is the lscpu output for the processor: AMD EPYC 7401 LscpuĪs part of our work in the sub $1100 CPU space, we have now benchmarked every Intel Xeon Silver and Bronze CPU, and all dual socket Intel combinations sub $2000. Here is the AMD product page with the feature set. Key stats for the AMD EPYC 7401P (and EPYC 7401): 24 cores / 48 threads, 2.0GHz base and 3.0GHz turbo with a whopping 64MB 元 cache. If you are buying a dual socket server with a single CPU, for future dual CPU operation after an upgrade, then the EPYC 7401 may make better sense. AMD has extraordinarily aggressive pricing on the EPYC 7401P. Let us be clear if you are putting an EPYC 7401 series in a single-socket only server, get the AMD EPYC 7401P not the 7401.
Beyond that, the CPU delivers 24 cores and 48 threads to a single socket at a price point under $1100, or about what Intel will sell you a 12 core Skylake-SP part for. The AMD EPYC 7401P offers a unique value that is largely unprecedented in the server CPU space: pricing under $45 per core and $23 per thread on higher core count parts. Today we have something that we have been waiting to share for some time, a special review of the 24-core AMD EPYC 7401P in single socket configuration.
