[QUOTE="muscleserge"]"Problems with the Architecture At the heart of both the Xenon and Cell processors is IBM's custom PowerPC based core. We've discussed this core in our previous articles, but it is best characterized as being quite simple. The core itself is a very narrow 2-issue in-order execution core, featuring a 64KB L1 cache (32K instruction/32K data) and either a 1MB or 512KB L2 cache (for Xenon or Cell, respectively). Supporting SMT, the core can execute two threads simultaneously similar to a Hyper Threading enabled Pentium 4. The Xenon CPU is made up of three of these cores, while Cell features just one. Each individual core is extremely small, making the 3-core Xenon CPU in the Xbox 360 smaller than a single core 90nm Pentium 4. While we don't have exact die sizes, we've heard that the number is around 1/2 the size of the 90nm Prescott die. IBM's pitch to Microsoft was based on the peak theoretical floating point performance-per-dollar that the Xenon CPU would offer, and given Microsoft's focus on cost savings with the Xbox 360, they took the bait." this is from http://groups.google.com/group/alt.games.video.sony-playstation2/msg/62ff83d96ea78ea9?hl=en basically both CPUs suck compared to a Pentium4. There is too much fanboyism in this thread.Killfox
I was waiting for someone to post this. Good job.
Cow won't listen, cold hard facts arnt good engough, not unless they are in thier favour.
