Nice benchmarks!
I just got a server with 2x Epyc 7402, and have also been doing some benchmarks involving MKL (using the quantum chemistry code ADF).
As on all non-intel chips, MKL will not automagically select the correct code path for fastest exectuion. The same holds true for multi-code-path (fat) binaries generated by the intel compilers (ifort/icc). However, for MKL there is a trick to work around this problem by setting an undocumented environment variable: MKL_DEBUG_CPU_TYPE=N, where N is an integer that corresponds to a vectorization set. N=5 should force MKL to use AVX2 instructions, instead of the default SSE2 on non-intel chips.
It would be really interesting to see the MKL benchmarks after doing "export MKL_DEBUG_CPU_TYPE=5"

Is the cost comparisons not a bit skewed by not including some base system costs?
e.g. a 1P base server costs eg. $2000 and a 2P base server costs e.g. $3000. What does a Epyc server cost without the cpu? What does a Xeon server cost without the cpu? Or is the calculation cost too much work?

I guess by now it's pc to say the Intel solutions are screaming "Help! I'm getting raped!" come the perf*dollar charts...

such a fine processor I could use my self compiling t2 all day, ... ;-) https://www.youtube.com/watch?v=TBC9C4L1J-k

AMD EPYC 7302 / 7402 / 7502 / 7742 Linux Performance Benchmarks
Phoronix: AMD EPYC 7302 / 7402 / 7502 / 7742 Linux Performance Benchmarks
Last month we provided launch-day benchmarks of the AMD EPYC 7502 and 7742 under Linux in both 1P and 2P configurations for these exciting "Rome" Zen 2 server processors. For your viewing pleasure today is a fresh look at not only the EPYC 7502 and 7742 processors under the latest Linux 5.3 kernel but we've also expanded it to looking at the EPYC 7302 and EPYC 7402 processors as well with those processors recently being sent over by AMD. Under Ubuntu 19.04 with Linux 5.3, these four different AMD EPYC 7002 series SKUs were benchmarked along with some of the older AMD Naples processors and Intel Xeon Gold/Platinum processors for a fresh look at the Linux server performance.
