Details
DD1.0
DD1.0, is the engineering sample of the XCPU, labelled XCPU-ES. It runs at 2.8GHz as opposed to the final speed of 3.2GHz. The ROM does not contain a 1BL, and thus these CPUs can only boot with a Titan board, which injects the 1BL. It still has the original Xbox logo as it was created before the Xbox 360 name was chosen.
- Part Number: X02046-001
- Foundry: Canada Foundry
DD2.0
DD2.0, is the production version of the XCPU running at 3.2GHz. There are 2 versions of the chip with different part numbers. It is not known what the difference between these two chips are. It also contains a programmed ROM containing the 1BL. Versions with part number X02046-002 used in certain pre-final consoles were still labelled "XCPU-ES" and still had the original Xbox logo.
- Part Numbers:
- X02046 (except -001)
- X806416
- Foundries:
- Canada Foundry
DD2.1
DD2.1 is a revision of DD2.0, with the notable change of reducing the TDP to 75W from the initial 85W.
