New model includes smaller graphics chipset.
A Sony spokesperson confirmed to IGN the company has now begun shipping new PlayStation 3 models to North America that include a 40nm RSX graphics chip.
The smaller chip allows the console to run cooler, consume less power, and, presumably, help Sony reduce manufacturing cost of the system. If you're on the lookout for the new unit, the model number is "CECH-2101A".
Sony's older PlayStation 3 models previously included 90mn and 65nm chip sizes. Last December, a report from research firm iSuppli noted Sony was close to breaking even with each PS3 sale. This new model may finally allow Sony to profit from its console.
Sony's annual fiscal results from this past week show the company has sold 35 million PlayStation 3 units since launch in 2006.
