I'd like to offer an actual data point in this discussion based upon my
Laptop A: 2yo IBM ThinkPad A22p (2629-Y1U) w/ 900Mhz PIII
Note: upgraded to the maximum 512MB RAM and running Red Hat 9
Laptop B: Brand-new (as of November) 15" 1.25GHz PowerBook G4
Note: upgraded to the max 2GB RAM and running the factory-
loaded OS X
Test: GCC (specifically, g77) compilation and runs of the
MITgcm (http://mitgcm.org/testing.html) verification suite.
Sure, its an esoteric thing but its what I do repeatedly in
a normal work day. And its something I'd like to see
Result: Laptop A beat Laptop B by an average of 19% (+/-2% over
multiple runs). Yes, the 2yo PIII soundly beat the brand new
G4. If you don't believe me, you're free to repeat it -- all
the software is publicly available.
Conclusion: While care was taken to shut down all other
applications on both machines, this was not a rigorous
benchmark. Rather, it was a quick and very informal
side-by-side test of two machines that we had on-hand
that day. That said, the Mac performance was not
inspiring. As a developer who is constantly building
and testing (most often with GCC), the Mac seemed *anemic*.
Perhaps things will improve with the G5 and ongoing GCC
optimizations. But in this case, x86 hardware running
Linux is a much "slicker" answer.
Of course, YMMV.
