Details

DD1

DD1 is the engineering sample of the XCPU with A00 stepping, labelled XCPU-ES. It runs at 2.8GHz as opposed to the final speed of 3.2GHz. Due to mistakes in the POR sequence, these CPUs can only boot with a Titan board functioning as a service processor to bring up the CPU. 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 initial production version of the XCPU with B00 stepping, running at 3.2GHz. 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 (-002 and -003)

DD2.1

DD2.1

DD2.1 is a minor revision of DD2 with B01 stepping, that improved yield and binned chips for 75W and 85W. This allowed most motherboards to have 75W CPUs.

  • Part Number: X02046 (-004 and up)

DD3

DD3 is a revision of DD2 that fixes minor design issues. With the new part number, the stepping reset to A00. All chips are 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
