Yeah, but if you look at the review from Anandtech, you see that AMD isn't on top. That goes to the ARM based servers.

The one from Phoronix also includes ARM Server, and it's very depending on the workload.

If you have a workload that can be very parallelized, ARM comes on top due to it's core advantage (160 cores). But if that's not the case, the ARM server tends to get crushed as then it's only on par with either Rome or in some even gets dominated by the the Xeon processor.

SPEC is also pretty optimized for the ARM chip; Phoronix tests in a way to not let the compilers get any "unfair" advantage and tries to have every competitor at equal arms to really find out what the CPU is capable for, not it's compiler.

With the Xeon being too slow and the ARM more dependent on the workload, the EPYC is the perfect Allrounder when it comes to performance imo. For the ARM chip, I also don't know how it is positioned in terms of PCI-E lanes and memory support, which can be very important questions for a server.
