And for the icing:
Now I know that the 970 and the cores used in the Cell and Xenon are different but I am feeling much better about the switch to Intel.Right now, from what weve heard, 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, its 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.
All you guys complaining about how IBM was screwing over Apple and giving MS 3.0GHz no longer need to worry. It was for the best.In the end, you get what you pay for, and with such a small core, its no surprise that performance isnt anywhere near the Athlon 64 or Pentium 4 class.
And for the icing:
The most ironic bit of it all is that according to developers, if either manufacturer had decided to use an Athlon 64 or a Pentium D in their next-gen console, they would be significantly ahead of the competition in terms of CPU performance.
