Waternoose1
Waternoose1 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. Waternoose1 still has the original Xbox logo as it was created before the Xbox 360 name was chosen. Waternoose1 is sometimes called "DD1.0"

Waternoose2
Waternoose2 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. Waternoose2 also contains a programmed ROM containing the 1BL. Versions of Waternoose2 with part number X02046-002 used in certain pre-final consoles were still labelled "XCPU-ES" and still had the original Xbox logo. Waternoose2 is sometimes called "DD2.0". The "DD2.1" version reduced the TDP to 75W from the initial 85W.
