There wasn't much of a difference in the rendering/modeling benchmarks.

With RHEL7 by default using PHP5 (though newer PHP releases are available through RHEL's Software Collections), RHEL8 offers much better PHP performance for those sticking to the software packages but not nearly as fast as Clear's optimized PHP.

RHEL 8.0 is also much faster now in the Rodinia workloads.

Lastly is a look at the geometric mean for these benchmarks and more across the four distributions on the two Intel Xeon Scalable servers. On the Xeon Gold server, RHEL 8.0 was 16.5% faster than RHEL 7.6. The RHEL 8.0 performance put it on par with Ubuntu 18.04.2 LTS while Clear Linux was 12% faster than those two enterprise Linux distributions in these tests. For the Xeon Platinum Cascade Lake server, RHEL 8.0 was 13% faster than RHEL 7.6 and again roughtly aligned with Ubuntu 18.04.2 LTS as would be expected given the kernels and compiler versions at play. Clear Linux on this Cascadelake Gigabyte Server was 12% faster than RHEL 8.0.

Stay tuned for AArch64 and AMD EPYC benchmarks from Red Hat Enterprise Linux 8.0 in the days ahead.
