New Xbox 360 (Valhalla) torn asunder

Zitat

The biggest improvement is actually when the system is totally off. The new Xbox 360 slim pulled 0.6W compared to over 2W for the older 360s while doing nothing more than being plugged in. Idle power is roughly 75% of what it was with the Jasper Xbox 360 and load power is around 80 - 83% of what we saw with the previous generation. Note that the new Xbox 360 consumes less than half the power of the original 360!

[...]The Xbox 360 slim is often referred to as what the first 360 should have been. It is smaller, quieter and hopefully much more reliable than what Microsoft first shipped five years ago. If it is indeed using 40nm components from TSMC I wouldn't expect a quick ramp. It may be that the slim remains at the $299 price point for a while until Microsoft can get enough silicon back to bring it to lower price points. Update: It looks like the CGPU is made at Chartered, now Global Foundries at 45nm. We may see a quicker ramp than I first assumed as a result.
