Sony has been improving it by leaps and bounds. I don't think its much bigger than 32MB anymore. It never really comes into the picture, performance-wise, in my experience. I'd be surprised if 3 CPUs with altivec co-processors could outperform 6 vector processors and another CPU with an Altivec. I sincerely doubt its possible. Each SPU is much speedier than the PPU's Altivec (identical to the Xenon core's Altivecs), when it comes to vector work. The Xenon cores can't do out-of-order processing, just like the PPU and the SPUs, and its branch predictor is practically worthless, just like the PPU's (they are basically the same core, with some interesting threading differences). The X360 CPU is, in essense, a PS3 CPU, with 3 PPUs, and no SPUs.

Well you can argue all you want with IBM. They are the figures and in real world terms the Cell as a whole gets nowhere near 200GFLOPS inside a PS3 for game usage. Although the Ram side can be improved (HOME will likely take that figure back up) The CPU usage cant be changed as much.
