According to a report from Nikkei late last week, Toshiba is planning on switching manufacturing of the PlayStation 3's RSX graphics processor to a 65nm process next month. Currently, the chip is manufacturing using a 90nm process, the same as it's been since the system's launch.
A smaller die size for the chip can mean cheaper production costs and less heat, contributing to lower prices for the consumer, and a quieter, more reliable PS3 system.
The latest versions of the system's Cell CPU are being manufactured using a 65nm process. It is widely believed that the switch to 65nm for the Cell is one of the main reasons Sony was able to drop the PS3's price down to $399 in time for the holidays.
Nikkei also reports that Toshiba is planning on beginning manufacturing at 45nm in the latter half of the next fiscal year, and speculates that the RSX and other PlayStation 3 chips are prime candidates for the new line.
