New PS3 Hardware Less Prone to YLOD | PS3Blog.net
Sony has recently started releasing new PS3 consoles that have an improved version of the RSX chip (the graphics processor). It uses 15% less power, and, according to GI.biz, is less prone to the YLOD issue. This is mainly due to going from 65nm to
45 40nm (the Cell, on the other hand, has been 45nm). A couple other changes have been found as well:
The console also now uses two 128MB XDR RAM chips instead of four 64MB chips and features a new cooling assembly and a lighter power supply.
Since this is only a minor hardware change, it doesn’t improve on game performance, but the changes do help on reliability. Sony hasn’t officially announced it since it is minor, so you could call it a shadow release. The model number is CECH-2100A in case you’re wondering.
EDIT: Small update.
