Last we heard, it was still up in the air somewhat as to whether upcoming PlayStation 3 consoles would house the elusive 65-nanometer RSX graphics processor.
According to couch21, a http://forums.slickdeals.net/showthread.php?sduid=0&t=902935 of Sony's newest 80GB unit, there is a smidgen of data that hints at a 65nm chip actually being under the hood. By using the oh-so-scientific Kill-A-Watt, he discovered that his older 40GB PS3 sucked down 125.8-watts when idle, while the fresh 80GB edition ate up just 111.9-watts.
The findings were similar when looking at power draw during DVD playback and while spinning Metal Gear Solid 4. Unfortunately, this mighty fine fellow is planning to return the new unit after being disappointed by the minimal energy savings, so he's not apt to rip the thing open and prove once and for all what kind of GPU is in there.
Meanwhile, we heartily suggest that someone do just that and put this question to bed. More PlayStation 3 News...
