80GB Core model draws less energy than 40GB

Looks like the 80GB Core PS3 may be more energy efficient than ever. A user at the Slickdeals forum connected his brand new 80GB Core system to a Kill-a-watt and discovered a slight energy savings. For example, the 40GB model used 155.2 watts when playing MGS4 -- the 80GB model used only 130 watts. The 40GB used 125.8 watts when idle on the XMB, while the 80GB used 111.9 watts. The popular theory is that Sony has secretly switched to new 65nm RSX chips: these are cheaper to manufacture, and are considered more reliable. Sony has not yet responded to these claims, but we wouldn't be surprised if each new SKU introduces new savings for the costly PS3 manufacturing process.
