Just to end this debate..
Nintendo Gamecube
CPU 486 MHz
GPU 162 MHz
RAM 43 MB
Sony Playstation 2
CPU 294.912 MHz (launch) 299 MHz (newer models)
GPU 147.456 MHz
RAM 36 MB
As far as power, for the sixth generation of consoles:
Xbox > Gamecube > PS2 > Dreamcast
But when it comes to sales (which is all that matters) the PS2 stomped all 3 combined. Which is why it won that generation of the console wars. Just like this generation (7th) was won by the Nintendo Wii which stomped out both the PS3 and Xbox 360.
And what's funny is, just like the PS2 before it, the Wii wasn't the most powerful system but it WAS the most popular. Which is why they won; because it doesn't matter how powerful or tech heavy a console is, if it doesn't catch on with consumers, it fails. Period.
