The folks at Ifixit love taking new tech apart as soon as they can get their hands on it. The PS3 Slim is no exception. You can see that a lot of changes have been made internally over the generations.


The heat sink in the new version is considerably smaller thanks to the 45nm cell processor, which also draws considerably less power.



And here's a look at the motherboard from a launch 60gb.



Notice the Emotion Engine and GS chips missing. Also the mystery chip on the top right has also disappeared. The motherboard is considerably smaller in the slim as well.

Update: The Mystery chip on the launch is the South Bridge, aka the I/O Controller. I'm not sure where it's been moved to on the Slim.
