  • Intel Sends Out Initial Linux Graphics Driver Support For "Elkhart Lake"

    It's busy as ever for the open-source Intel Linux graphics driver developers bringing up support for upcoming hardware like the recently published driver patches for Comet Lake, continuing to tweak the maturing Icelake "Gen 11" graphics, and also plotting the necessary re-engineering of the driver needed to bring-up Intel's in-development "Xe" discrete graphics. And Intel developers this evening sent out their initial enablement work for Elkhart Lake.

GCC vs. Clang Compiler Benchmarks On POWER9 With Raptor's Blackbird

While for Intel x86_64 with the latest compilers it's a very competitive race between LLVM Clang and GCC, how is that battle playing out on the IBM POWER9 front? Using the interesting Raptor Blackbird with IBM POWER9 4-core / 16-thread CPU, here are some recent benchmarks I did between GCC 9, GCC 10, and LLVM Clang 8. Last month using the Raptor Blackbird with quad-core / sixteen thread IBM POWER9 CPU while running Ubuntu 19.10 ppc64le, I ran compiler tests while using GCC 9.1.0 stable, GCC 10.0 snapshot from mid June, and LLVM Clang 8.0.1 as some reference tests for seeing how these compilers are performing for POWER9. All tested compilers were in their release/optimized builds and various POWER-friendly C/C++ benchmarks were carried out for checking on the performance impact of the different generated binaries.
