Skylake AVX-512 Benchmarks With GCC 8.0
For those curious about the current benefits of AVX-512, here are some benchmarks using a recent snapshot of the GCC 8 compiler and comparing the performance of the generated binaries for the skylake and skylake-avx512 targets.
AVX-512 right now is limited to just the Intel server and X-Series processors, but as we've reported already, Intel has effectively confirmed AVX-512 support for the Cannonlake desktop CPU line-up through GCC/Clang patches noting the AVX-512 addition. So due to greater AVX-512 availability on the horizon and continued AVX-512 improvements in GCC8, I ran some fresh benchmarks using the high-end Core i9 7980XE test system running Ubuntu Linux.
