Let's take things from the start. Technically, CPU architecture refers to the instruction set of a CPU. Examples are, x86, ARM, MIPS etc.
Both the 360 and Wii U use PowerPC architecture. There is no "exotic" architecture involved, like PS3's mixed-core solution. Now obviously, some people want to believe that there is immense untapped power in this system. The cold hard truth is that Nintendo's system is based on 40-45nm silicon and runs at 75 Watts during full blown game-play. 80 dollar video cards from the same process node run at 100-130 watts. If you understand the principles of semi-conductor size and power consumption, then you know what I'm talking about. There is barely any hardware inside that console.
