According to megagames (http://www.megagames.com/news/show.cgi?&idtype=hardware&database=332&page=0&) the next gen makers (microsoft and Sony) made a mistake by going with IBM for it's next gen Cpu's. These new cpu's may actually be a major bottleneck on what otherwise could've been a major leap forward.



For all their differences and the marketing trickery employed, the X360 and PS3 CPUs have a very obvious connection; they are both based on the IBM PowerPC core. So what drives these two consoles? At the heart of both machines lies a core featuring 64KB of L1 cache (32K reserved for instruction and 32K for data) and a 1MB L2 cache for X360 and a 512KB L2 cache for Cell.
This core supports SMT and can simultaneously execute two threads similarly to a Hyper Threading enabled Pentium 4. The X360 CPU carries three such cores while Cell has one. It seems that both Microsoft and Sony were convinced to invest in the IBM core based on the theoretical peak performance of the chip and its, relatively, low price. This sleek pitch by IBM has also been transferred to the consumer through the PR departments of both competitors as they have been comparing the theoretical 1 TFLOP processing power of the X360 CPU to the 2 TFLOPs produced by the Cell array.

OK, I hear you ask, what does that have to do with us? What all this comes down to is that the processor on Xbox 360 is expected to be twice as powerful as the 733MHz Celeron hybrid of its predecessor in real world performance. This would make the X360s CPU, slower than most current CPUs, even though that particular one has to last Microsoft for 4-5 years. The issue, experts tell us, is the small core of the IBM chip and its branch predictor, which is not the finest available.

Unfortunately consoles will never compete with PC..it's just the way it is. Good reason too. People will spend 3 grand on a PC where as you spend 400 on a console. Not to mention every year you have to upgrade your video card to play the latest and greatest games so you have that extra 10 FPS ;)

but these consoles don't need these high end processors. Computers are doing many things at once. These consoles don't need all of that power. The big thing you really need to look at is the video cards. Which both are more powerfull there than most computers right now.

The big thing you really need to look at is the video cards. Which both are more powerfull there than most computers right now.They "may" be one generation more powerful, the problem I see is the shared ram, and if your processor is a bottleneck, then you cannot take full advantage of the video card. IF you system has any bottleneck, it degrades the performance of the whole thing.
