Jim. This will give you an idea of what eight 64Mb DDR chips might look like on the Xbox board.
The graphics card here is the 3D Prophet II GTS Pro using the NVIDIA GeForce2 Pro with 64MB DDR. The 64Mb chips are mounted four front and four back.
(Note: these are 200MHz DDR chips and require heat sinks).

Jim,

DDR needs a very big bus to deliver the goods.

DDR uses a wider bus. This allows it to achieve higher bandwidth at a lower frequency, and is the main reason that everyone is designing around DDR instead of RDRAM.
