40nm RSX Allows for Lightest, Most Efficient PS3

As part of the usual improvements throughout the console life cycle, Sony has updated the design of its PS3 Slim.

The major change this time wasn't a new feature or a new form factor, but rather a die shrink for its Nvidia-designed RSX GPU. The chip has shrunk from 65nm to 40nm, resulting in a reduction in both weight, heat, and power consumption.

A teardown narrated by Japanese site PocketNews examines the power requirements and updated (and simplified) designs for the cooling system. Compared to the original launch console, the new 40nm RSX-packing model CECH-2100A weighs nearly half of the first PlayStation 3 design.

Perhaps equally remarkable is that the new model weighs significantly less than the PS3 Slim model unveiled last fall. The latest design, with its simpler cooling and lighter power supply, weighs 408g, while the PS3 Slim launched last year weighs 545g.

Expectedly, the die shrink has reduced power consumption by around 15 percent – an improvement in all powered-states. When powered off, the console still draws 9W.

    The new chip also allows the engine to rev well past 8000rpm thanks to it's K20 technology.

    Why would I care how much it weighs when for me a die shrink means better performance, or is this G80-G92 all over again?

    I honestly would have kept the old heatsink. You can never over cool it. And then even a dirty heatsink will still have the cooling needed.
