AMD EPYC 7003 "Milan" Linux Benchmarks - Superb Performance
As you saw from those geometric means based when grouping of similar benchmarks, the AMD EPYC 7003 series line-up comes out stunningly great with sizable generational uplift while working as a drop-in replacement to EPYC 7002 systems pending BIOS updates. Now let's look at some of the individual benchmarks for the complete selection of CPUs tested (or re-tested in case of prior models) in both 1P and 2P configurations.
While only having a short time to test the EPYC Milan processors so far, their performance has been quite commendable.
With these top-end Milan processors it's possible to build the mainline Linux kernel in under 20 seconds in its default configuration.
The CPU package power consumption of the EPYC 7713 2P was around 14 Watts higher on average than the 7742 2P while the 280 Watt TDP EPYC 7763 and 75F3 parts obviously consumed more. During the benchmarking process the Phoronix Test Suite was monitoring the CPU package power consumption exposed by the Intel and AMD drivers on Linux. This allowed for real-time power consumption monitoring on a per-test basis and thus also generating performance-per-Watt graphs where appropriate.
Compiling the LLVM compiler stack on these Milan processors could be achieved in about three minutes or less.
On a performance-per-Watt basis, the Milan results were comparable to Rome in a 1P configuration or for 2P came out ahead with LAMMPS.
