64 MB DDR SDRAM at 200 MHz; in dual-channel 128-bit configuration giving 6400 MB/s
The console features 512 MB of GDDR3 RAM clocked at 700 MHz with an effective transmission rate of 1.4 GHz on a 128-bit bus. The memory is shared by the CPU and the GPU via the unified memory architecture. This memory is produced by either Samsung or Qimonda.

also some quotes about the original xbox:
- Code: Select all

and from the xbox360:

main to to take from this is that although there are 128bit registers, and a 128bit memory bus, and all kinds of 128bit magic.. there is no cpu with a 128bit instruction set and frankly... I wouldn't know what to do with that many instructions.
so although microsoft has experience with some 128bit things, what does a 128bit OS actually mean? which parts of the cpu are 128bit and what does that change? I don't think we really need much more memory addresses.. so increasing that would be kinda pointless.. on the other hand getting twice as much data for each read/write would double the speed without increasing the clock speed(note the difference between the address bus and data bus). And larger registers could possibly be useful for floats.
I wouldn't hold my breath for a 128bit machine, especially not a desktop. Servers or game consoles seem most likely to take this step but I can't really see a reason why they'd bother.
