for a very details technical look in the ps3 vs 360 read
this.
its a very good article, and unbiased. Over all both the 360 and ps3 have there own pros and cons. But he did point out that the 6 cells (one cell is used only for the OS and can't be used for games) are more powerful than the 360 3 PPE's but the xbox 360 are more robust and easier to program for.
now, potentially the ps3 can produce "busier" games than the 360, but very complex and accurate proraming is need to use all 6 cells at once, at their max. The question is, how hard is it?
