Ryzen Compiler Performance: Clang 4/5 vs. GCC 6/7/8 Benchmarks

A few days back I posted some fresh AMD Ryzen compiler benchmarks of LLVM Clang now that it has its new Znver1 scheduler model, which helps out the performance of Ryzen on Linux with some of the generated binaries tested. But it was found still that Haswell-tuned binaries are sometimes still faster on Ryzen than the Zen "znver1" tuning itself. For continuing our fresh compiler benchmarks from AMD's new Ryzen platform, here are the latest GCC numbers.

StarTech 12U Computer Rack

In needing to make more room for Ryzen/Epyc/ThreadRipper and Core-X Series, the StarTech 12U rack was the latest investment. This 12U rack can, fortunately, fit quite comfortable under my custom-made desk.

Haswell-Tuned Binaries Are Still Sometimes Faster On AMD Ryzen Than Znver1 Tuning

Yesterday I posted benchmarks of Clang 4 vs. Clang 5 with AMD Ryzen now that LLVM 5 has received the initial AMD Zen "znver1" scheduler model. That scheduler model and improvements to LLVM/Clang 5.0 yielded some performance improvements, but still there are cases where using "-march=haswell" for tuning and running those generated binaries on Ryzen leads to better performance.

NVIDIA's Server-Side GLVND Implementation

Earlier this week I wrote about Adam Jackson's work at Red Hat on a prototype of an X.Org server-side GLVND implementation. NVIDIA has also now announced their coincidentally similar work.
