Better, but obviously there is still much room for improvement by reducing

Hmm, is there some way we can easily tell we are running on Ryzen? Or
do we believe this is going to be true for all AMD devices?
I would like to note that my first measurement on Broadwell suggest that
the current frequency of RDRAND calls seems to slow things down on Intel
also (but not as much as on Ryzen).
