Is the PlayStation 3 most powerful console?

Answer 1

When you look at the specs i believe the ps3 is a hair more powerful above the Xbox 360 but it is not really noticeable

The wii is in a whole different world when it comes to power ( way less than ps3 and xbox 360).

The Xbox 360 utilizes a tricore Xenon processor clocked to 3.2GHz. While the PlayStation 3's Cell processor also runs at 3.2GHz, it instead has seven synergistic processing units, controlled by another power processing unit. Theoretically, the PlayStation 3 is thus more than twice as powerful as the Xbox 360. The PS3's Nvidia-developed Reality Synthesizer also runs at 550MHz compared to the 360's 500MHz ATI GPU. Finally, the PS3 has XDR RAM with speeds of 3.2GHz, identical to its CPU. On the other hand, the 360 uses the older GDDR3 RAM running at 700MHz. Your system is only as good as its worst component, so the 360 has already lost.
