Wii Technical specifications
Nintendo has released few technical details regarding the Wii system, but some key facts have leaked through the press. Though none of these reports has been officially confirmed, they generally point to the console as being an extension or advancement of the Nintendo GameCube architecture. More specifically, the reported analyses state that the Wii is roughly 1.5 to 2 times as powerful as its predecessor.[2][80] Based on the leaked specifications, the Wii is the least powerful of the major home consoles in its generation. The Wii uses a storage system similar to the GameCube, which uses "block" units rather than bytes. The conversion from blocks to bytes is roughly 8.12 blocks to one megabyte.
