The new Xbox 360 is the most technologically advanced yet thanks to the CPU and GPU sharing one chip on the 45nm scale. It's quieter, cooler and less energy hungry—sucking half the power of the original.

AnandTech put the new 360 through its technical paces. Their findings:

• It's "noticeably quieter," spinning discs at 51 dB(A) rather than 54 dB(A) of last gen
• Idling, it's 6dB(A) lower than that—indeed, about the volume of a whisper just as Microsoft claimed


• Power consumption dropped more than 50% from the original Xbox (idling, and about that much during gameplay)
• Compared to the most recent model, power consumption dropped roughly 20%
• Vampire power is down to 1/4 that of all other 360s, .6W
• You'll still need a T8 torx to disassemble one

If you REALLY want to get into the nitty gritty, AnandTech has even more in their original post. [AnandTech via Engadget]

EXTREMELY GEEKY DISCLAIMER: AnandTech speculates that Microsoft may be using 40nm manufacturing. Microsoft confirmed with us that it's 45nm.
