IBM is producing the Cell microprocessor at 65-nanometers, shrinking it down from the previous generation, the company said Monday.

Cell is the chip inside the Playstation 3, and it was jointly developed by IBM, Sony and Toshiba. IBM didn’t provide any details about the new 65-nanometer chip, other than to note it was now in production.

Moving to smaller tranistors gives chip makers a few options to improve performance. Basically, they can now fit more transistors on the same size chip, or reduce the size of the chip with the same number of transistors. This helps increase performance, reduce costs, or both.
