Yes, it's rather depressing to see everything getting overrun by
Intel. I'm sitting here rooting for the Hewletts and Packards to
block the merger (that might save Tru64), but Alpha is dead
nonetheless. Still, today it remains well ahead of the performance
found in PC CPUs. As for IRIX, well, what *isn't* faster than MIPS?
Maybe the G4? :-)
Since there's no OS X version of the Tru64 software I use to do work
at work, but I got the JTR password cracker to compile on OS X, I
decided to let my computer at home do the looking for weak passwords
on the accounts from work. Running that, the Alphas are 8 times
faster than my G4. The Alpha happens to be particularly good at DES
but even on other things a G4 has a way to go before it reaches the
level of the Alpha.
Maybe the G5 will be better, but I've been more impressed with IBM's
POWER chips than anything Motorola has cooked up recently. Motorola
doesn't even bother with SPEC benchmarks any more. They're the only
mainstream processor maker I'm aware of that doesn't. There isn't a
single SPEC2000 number from Motorola in SPEC's database. SPEC isn't
perfect but it seems to be about the most useful benchmark set.
Because of that I've really lost track of how fast the G4 is relative
to other chips, but everything I've seen suggests the G4 is near the
bottom of the pack performance-wise, unless you have AltiVec-enhanced
software. That doesn't matter for day to day use; I'd rather have a
nice OS in Mac OS. But I would hate to be stuck with a bunch of G4s
for the FP-intensive number crunching I currently run on Alphas.
All the technical software I use at work appears to be headed towards
Linux (not OS X) as an eventual preferred platform, but the Linux
versions are rather immature and buggy at this point (and they only
work on x86 Linux). For what I use, Linux looks like it has a great
future. But it has no present.
