That's very impressive, how much performance can be finagled from the general prupose CPU.
Maybe it would be educational if somebody explained what the change consisted of on a tech-
nical basis, also going into the MMX instruction set more generally.
That would both provide an educational opportunity and a common language for discussion on
core architecture.

Thanks,
David

A new optimized core was added which uses assembly routines and mmx
instructions.
