"The GameCube's ATI GPU, also known as "Flipper", actually integrates the North Bridge and I/O controllers along with the graphics processor in a single 106 mm square chip containing approximately 51 million transistors. The entire Flipper chip runs (or rather, swims) at 162MHz - including the graphics core. 3MB of embedded 1T-SRAM from MoSys can be found in the GPU, as well as another 24MB of this same 1T-SRAM on the mainboard outside of Flipper for the system's main memory. The pipelines to these memory modules (which can sometimes be a major bottle neck in some systems) are shorter and speedier than their counterparts in the XBOX, proving yet again that the GameCube was designed for efficiency rather than pure power."
