AMD A10-5800K Trinity APU testing when trying out different compiler tuning flags from the GNU Compiler Collection (GCC) with different CPU micro-architecture targets. Benchmarked configurations from the AMD A10-5800K include -march=k8, -march=k8-sse3, -march=barcelona, -march=bdver1, and -march=bdver2. -march=bdver2 is the native target for the A10-5800K as a Bulldozer 2 / Piledriver product.
