Well... you could look at 
http://www.goof.com/pcg/  and
http://www.redhat.com/products/support/gnupro/gnupro_gcc.html

Or trawl the developer.intel.com site for info on optimisations for
specific processor families.

www.emulators.com has some amusing rants too, and there are many sites
dedicated to uncovering x86 CPU "secrets". 

Be aware that it's Deep Geek though. Assembly language ahead. ;-)
