AMD Compiler Optimization Benchmarks With GCC 4.10 (GCC 5.0)
As a continuation to yesterday's brief GCC 4.9 vs. GCC 4.10 (GCC 5.0) comparison with the AMD A10 A-Series "Kaveri" APU, here's some benchmarks when using the GCC 4.10 development snapshot and trying a variety of CFLAGS/CXXFLAGS to see the current impact on their performance for a variety of Linux benchmarks.
For another straightforward, simple benchmarking article this weekend are the reference results when running the A10-7800 APU system with Ubuntu 14.04 64-bit on the freshly-built GCC 4.10 development snapshot with a variety of common x86 compiler flags for AMD hardware. The flags included:
-march=k8
-march=k8-sse3
-march=barcelona
-march=bdver1
-march=bdver2
-march=bdver3
-march=bdver3 -flto
Documentation for these flags can be found via the GCC documentation.
The results themselves for this new AMD Kaveri APU with these various compiler flags aren't a huge surprise. You can find all the data on OpenBenchmarking.org. Enjoy and feel free to run your own compiler benchmarks with the Phoronix Test Suite.
