heres is an interesting explaination
In making Wii U, the development team had a particular goal in mind. The staff wanted to maintain high efficiency and performance while keeping power consumption low.
Takeda explained that the Wii U uses a multi-core CPU. With it, “data can be processed between the CPU cores and with the high-density on-chip memory much better, and can now be done very efficiently with low power consumption.” The console also makes use of a MCM, which houses the multi-core GPU, CPU, and LCL chips. Shiota noted, “By putting LSI chips in this small package, the power necessary for communication between LSI chips drastically fell.
