I wonder how 1P vs 2P would affect memory bandwidth. The 1P vs 2P difference would probably be deeper than just CPU clock speed.

Also, I wonder if these were Meltdown and Spectre patched.

If you are memory throughput bound, and both processors are working independently (think embarrassingly parallelizable problems) you'd probably benefit from the total throughput change.

Otherwise it's pretty easy to get worse performance due to numa issues

EPYC is already four NUMA nodes per socket though.
