AMD EPYC Rome VMware Review (7702P, 7402P, and 7302P)

Recommended Posts

The AMD EPYC 7002 came out with the promise of more performance with fewer sockets. Now that VMware fully supports the new CPUs, we continue with our testing to show the promise of the new processors. For this review we were able to test three distinct AMD EPYC CPUs in a traditional VMware environment. This testing wasn’t to show which is better, that is typically the one with the highest core count. Instead we tested the different CPUs for readers to get an idea what to expect, so they can better choose the processor that is right for their use case.

I think there are some ways that you could improve the value of your testing to the reader, that are based on the setup and applicability of the results in a CPU scaling determination:

Core count:

You ran the same number of 16 core VMs on all CPUs. Resulting in massive CPU wait state performance impacts by over-provisioning the vCPUs when run on the 7302P (16C/32T) and to a lesser extent the 7402P (24C/48T). This largely explains the massive latency increase on the 7302P. I understand these are your usual tests, but in this instance, I think it would have been very useful to have run this test with multiple VM counts, such as at 1, 2, 4 and 8 SQL VMs and then we could produce a SQL performance per $ metric as a result. 

As a result, the review is more an exercise in showing the impact in the VMware world on CPU over-provisioning thresholds when dealing with processor-intensive workloads.

As you allude to in the closing paragraphs, many people are interested in these CPUs in single socket designs to save on VMware licensing costs. I would love to see a review of the 7402P, 7502P and 7702P models against systems with two comparable Intel dual-socket CPUs. Such as the 7502P vs two Gold 6242 Xeons. If you can run those tests and 2, 4, 8 and 16 VMs plus add in your VDI testing, that would be an extremely valuable review to many of your readers.

Thank you for all your hard work on providing independent news and reviews! Storage review is one of my frequent visits, so keep it up!
