i think its funny what anandtechs article was saying how poor the cpu's in both systems are compared to current pc ones.
quick copy:
the real-world performance of the Xenon CPU is about twice that of the
733MHz processor in the first Xbox. Considering that this CPU is supposed to power the Xbox 360 for the
next 4 - 5 years, it's nothing short of disappointing. To put it in perspective, floating point
multiplies are apparently 1/3 as fast on Xenon as on a Pentium 4
The reason for the poor performance? The very narrow 2-issue in-order core also happens to be very deeply
pipelined, apparently with a branch predictor that's not the best in the business. In the end, you get
what you pay for, and with such a small core, it's no surprise that performance isn't anywhere near the
Athlon 64 or Pentium 4 class
Final Words Just because these CPUs and GPUs are in a console doesn't mean that we should throw away years
of knowledge from the PC industry - performance doesn't come out of thin air, and peak performance is
almost never achieved. Clever marketing however, will always try to fool the consumer.
