To me it seems perfectly fair to compare an $N Intel system to an $N
Alpha system, regardless of anything else.

I disagree. The proper comparison is by price/performance ratio. If
I can get better performance from an $N Intel system than from an $N
Alpha system, how can you say the Alpha is better?
One thing I should have mentioned before, though, is that it's
entirely possible that the disappointing -mieee performance on the
Alpha is due to inferior code generation by gcc. Maybe that can be
improved in future versions of the compiler.
