The Xbox 360’s CPU has more general purpose processing power because it has three general purpose cores, and Cell has just one.

Cell’s claimed advantage is on streaming floating point work which is done on its seven DSP processors.

The Xbox 360 GPU has more processing power than the PS3’s. In addition, its innovated features contribute to overall rendering performance.

Xbox 360 has 278.4 GB/s of memory system bandwidth. The PS3 has less than one-fifth of Xbox 360’s (48 GB/s) of total memory system bandwidth.
CONCLUSION
When you break down the numbers, Xbox 360 has provably more performance than PS3. Keep in mind that Sony has a track record of over promising and under delivering on technical performance. The truth is that both systems pack a lot of power for high definition games and entertainment.
However, hardware performance, while important, is only a third of the puzzle. Xbox 360 is a fusion of hardware, software and services. Without the software and services to power it, even the most powerful hardware becomes inconsequential. Xbox 360 games—by leveraging cutting-edge hardware, software, and services—will outperform the PlayStation 3.
