Looking at the numbers, I am a little disappointed that a Dual 2.0 GHz
G5 system is less than twice as fast as a single 3.0 GHz P4. A quick
search reveals that there are many available dual P4 (Xenon) systems
that they could have tested. I wonder why they didn't ? I also
notice that Adobe says the new systems are faster than any other APPLE
system. Yes. What about non-Apple systems ?
Are you sure you looked at the numbers carefully?
_ALL_ of the application comparisons (Photoshop, Luxology, and
Mathmatica) that Apple did at the keynote were against a Dual Xeon 3.06
GHz system and the Dual 2 GHz G5 was easily twice as fast in each
application. Here are the actual numbers for the application
comparisons:
Adobe Photoshop: G5 is 2.1x faster
Luxology: G5 is 2.3X
Mathmatica: G5 is 2.1X
Again, this was against a Dual 3.06 GHz Xeon system. On Apple's site,
the SPEC scores aren't quite as good but they were done on both the G5
and the Xeon with the same compiler, GCC 3.3. This is good because
Intel likes to use their own benchmark-optimized compilers for their
numbers.
Go to this page,
http://www.apple.com/powermac/performance/, to take a
look at the SPEC scores. The G5 beats the Xeon and the P4 in all tests
except for single-processor SPECint where the G5 is 10% slower than a 3
GHz P4. But the dual processor G4 beats the dual processor Xeon in all
scores and is almost double the single processor P4.
So these systems do seem to be almost twice as fast as single P4 in
SPEC, but application comparisons show that they're more than 2x as
fast as even a dual Xeon. I think these machines are going to smoke
the competition.
