With gcc on non-x86 targets, you would be surprised...
The current release (improved) gcc 3.1 Apple ships with Mac OS X 10.2 is
still about 50% behind the Mac GUI version (which uses CodeWarrior). And
the 3.3 they used for the latest test is not much better....
Anybody using gcc to benchmark a Mac (or any system for that matter) with
anything must be insane. However, as Steve Jobs apparently wants everything
under his control, in particular the development tools, they apparently
didn't even bother to ask Metrowerks to provide a prerelease 64 bit version
of the PowerPC backend of CodeWarrior (it targets a few 64 bit embedded
targets with the same frontend already).
Fact is, IBM announced much better SPEC base 2000 results for the 1.7 GHz
version last year, and those were probably based on the same compiler they
use for the Power4.
Sadly on mac OS X Apple effectively closed to road to use AIX executables
because Appole switched to the Mach kernel ABI, which is terribly
inefficient mostly because it also contains some garbage Next added to
support Objective C <sigh>
