9-Way Intel Xeon E3 v5 Skylake Benchmarks On Ubuntu Linux

First up is the venerable HPC Challenge (HPCC) that I couldn't resist running on this nice assortment of Xeon processors.

The HPC Challenge HPL performance was interesting. There isn't too much difference in the Xeon E3 v5 results where the CPU is quad-core plus Hyper Threading and the turbo clock speeds in the upper 3s. More interesting will be the performance-per-Watt and performance-per-dollar results on the later pages. To no surprise, coming out ahead of the E3 v5 CPUs was still the higher-end Haswell systems of the i7-5960X EE, E5-1680 v3, and E5-2687W v3 as they have more physical cores than the other processors tested. The AMD FX-8370 was in a distant last place.

Interestingly for the Dolfyn scientific benchmark, the Xeon E3 v5 CPUs with their generally higher clock speeds and newer architecture were able to outperform the E5 Haswell CPUs and i7-5960X EE. The $199 AMD FX-8370 continued to trail all of the other $193~294 Intel processors tested along with the more expensive models.

It's a similar story as well with the LAMMPS molecular dynamics benchmark.

The E3-1270 v5 and E3-1280 v5 perform close to one another as they are both quad-core plus have Hyper Threading and the same 4.0GHz Turbo frequency while the E3-1280v5 has a 3.7GHz base frequency rather than 3.6GHz.
