What? Are you talking memory bits? Or something more internal?
Because the origional Xbox had a 128bit memory bus with 6.4GB/s of bandwidth.
The Xbox 360 however had a 128bit memory bus with 22.4GB/s.
Where the Xbox 360 deviates is with the eDRAM.
It has 256GB/s of bandwidth inside the eDRAM which is actually 1024bit@2ghz = 256GB/s.
However, that's not interconnect bandwidth to the GPU or system memory, the bandwidth between the eDRAM and the GPU is 32GB/s.
If you want wan't a fair comparison Sandy Bridge has an internal ring bus that's 436GB/s.
The Radeon 3850's Ring bus was also 1024 bit.
The Radeon 48xx series had a 2048bit internal hub bus.
So this is actually nothing new.
However when you start talking interconnect, then it's simply not going to happen, 4096bit busses would drive up PCB/package complexity exponentially.
Basically, no part of the Origional Xbox or Xbox 360 had a 4096bit bus, unless you know something I don't know from an architectural perspective?
