A teardown video of an XBOX 360 and analysis of GPU silicon die from Electronupdate.
So, what makes an XBOX tick? One of the most notable parts will be the graphics sub system… and at the heart of it, the GPU.
The GPU die is bonded onto a substrate with an associated frame buffer just to the left of it. This complex assembly is our 1st hint that the engineers were pushing the envelope of technology…. this “should” be only on one die… it’s a bit of cost adder to do it this way.
Awesome! That means the GPU is going to be complex indeed!
