Specifications
Waternoose1
The Waternooose1 is the initial engineering sample, labelled XCPU-ES. It runs at 2.8GHz as opposed to the final speed of 3.2GHz. The ROM does 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.
- Part Number: X02046-001
- Foundry: Canada Foundry
Waternoose2
The 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.
