Rob,
When IBM supported the Mac, I also did a comparison and found that xlc
and xlf were from 20% to a factor of 2 faster than gcc and g77 (on a
G5). More recently, when IBM released free versions of these products
for the Cell, I did a comparison and found very little difference for
both
Hi Warren:
I hope that you are well. I just want to highlight something. It was
Apple which walked away from IBM's consortium regarding PowerPC
development which led up to the Cell, not the other way around. Apple
may yet crumble due to the fact it continues to be the least secure
commercially
