That's certainly true. But if that's your workload you shouldn't be buying a 64-core CPU...
I use a few 32 and 64 core machines for build servers and file servers, and while the 64-core EPYCs are not twice as fast as the 32-core ones due to lower overall frequency, they're 70% or so faster in most of the things I throw at them.
