"Lastly, we were sent updated spec numbers on the Xbox's numbers, and we spoke with Microsoft's Vice President of hardware, Todd Holmdahl, about the Xbox 360's final transistor count.
Another bit of information sent our way is the final transistor count for Xbox 360's graphics subset. The GPU totals 332 million transistors, which is spit between the two separate dies that make up the part. The parent die is the "main" piece of the GPU, handling the large bulk of the graphics rendering, and is comprised of 232 million transistors. The daughter die contains the system's 10MB of embedded DRAM and its logic chip, which is capable of some additional 3D math. The daughter die totals an even 100 million transistors, bringing the total transistor count for the GPU to 232 million."
