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
DD1 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
DD2
DD2 is the production version of the XCPU running at 3.2GHz. It also contains a programmed ROM containing the 1BL. Some later versions were binned for 75W while the earlier chips were 85W. Very early versions with part number X02046-002 used in certain pre-final consoles were still labelled "XCPU-ES" and ran at 2.8GHz.
- Part Number: X02046 (except -001 suffix)
DD3.0
DD3 is a revision of DD2 that fixes minor design issues and lowers the TDP to 75W. It also adds little-endian support which was unused due to all software features requiring full compatibility with the earlier DD2 chip.
- Part Number: X806416
