though it seems logical that this would probably be less of an issue for AMD if they manufactured CPUs or GPUs for the Xbox 360 or PlayStation 3

Errr.... am I missing something? Confused

"Fast forward to 2005, Microsoft revealed that the Xbox 360 will feature a custom ATI graphics processor that clocks in at a blistering 500 MHz, with 48-way parallel floating-point dynamically scheduled shader pipelines and 10 MB of embedded RAM."

The Xbox 360 S introduced the XCGPU, which integrated the Xenon CPU and the Xenos GPU onto the same die, and the eDRAM into the same package. The XCGPU is the first mass marketed chip that combines a desktop class CPU, a powerful GPU, memory controllers and IO. It also contains a "front side bus replacement block" that connects the CPU and GPU internally in exactly the same manner as the front side bus would have done when the CPU and GPU were separate chips, so that the XCGPU doesn't change the hardware characteristics of the Xbox 360.

XCGPU contains 372 million transistors and is manufactured by GlobalFoundries on a 45 nm process. Compared to the original chipset in the Xbox 360 the combined power requirements are reduced by 60% and the physical chip area by 50%.[8][9]

The Xenos GPU is an ATI design.
