What's the point of per GHz comparison? The P4 and the Athlon aren't

Since both Intel and PGI make their compilers temporarily available
for free -- beta-test until September for Intel, trial version from
PGI -- you might as well test with the best compilers, instead of the
ones you happen to own.
