Lets just ignore the price point for now because the memory capacity are different.
But the performance, 24 Core AMD EPYC Zen is ~35% faster than 24 Core Intel Broadwell Xeon under the same frequency?
Broadwell isn't even that old because Intel has only launched Skylake Xeon E5 not long ago. And the different between Skylake and Broadwell IPC aren't that much either.
the max turbo speed are similar, and the Intel platform had the advantage of two CPU using two heatsink, higher TDP, higher heat dissipation more time for turbo.
And most testing has shown Zen to be about Sandybridge IPC performance. Something seems wrong here ( Or may be too good to be true )
