The Waternoose series are the original production model of the XCPU and are used on Xenon and Zephyr motherboards. They have 75-85W TDPs and are manufactured on a 90nm process.

They are named after the fictional character Henry J. Waternoose III.

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.

  • Foundry: Canada Foundry

DD2.0

DD2.0, is the production version of the XCPU running at 3.2GHz. It also contains a programmed ROM containing the 1BL. Early versions with part number X02046-002 used in certain pre-final consoles were still labelled "XCPU-ES" and ran at 2.8GHz.
