The Waternoose series are the original production model of the XCPU used in the Xbox 360.

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.

  • 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.
