The Impact Of GCC Zen Compiler Tuning On AMD Ryzen Performance
The libjpeg-turbo performance was barely impacted by the compiler optimizations.
The HINT performance also didn't budge with the compiler tuning.
For those curious how enabling znver1's impact on build time, here are those benchmarks.
It will be interesting to run these tests with GCC 7 and LLVM Clang 4 to see if the Zen tuning is any better with those compilers. While Zen compiler tuning has been happening in the public since 2015, it seems there is still more compiler work needed, especially as from our compiler benchmarks with Intel their processors seem to benefit much greater from compiler tuning. Stay tuned!
