> -march=native is ambiguous, please see with -v what actually is being used.
This was mentioned in the initial comment:
-march=k8-sse3 -mcx16 -msahf
--param l1-cache-size=64 --param l1-cache-line-size=64 --param
l2-cache-size=1024 -mtune=k8
The latest timings are on a newer machine (old one is gone now) which has:
-march=amdfam10 -mcx16 -msahf -mpopcnt -mabm --param l1-cache-size=64 --param
l1-cache-line-size=64 --param l2-cache-size=512 -mtune=amdfam10
