Yes, and no.
Things like disk IO, gcc version, and cache can all effect compile
time. But yes, IMHO I think the cache size difference would make a
large difference.

Just something to think about... How about cutting down your compile
down even more. Use distcc to allow both machines to help in the
compiling. I used to do this, until I got an AMD64, and well, I was
too lazy to setup a chroot so other machines could benefit from the
power, but I originally used distcc when I played with gentoo, and
it's a great way to reduce things like kernel compile time!!
