It’s not too hard to believe that Sony would have tinkered under the hood of the PS3 Slim and today we’ve learned that those assumptions are, in fact, true. The Slim now has a 45-nanometer Cell microprocessor, which was jointly developed by Sony, Toshiba and IBM.
Benefits of the new fangled chip based on IBM’s Power architecture promises improved performance with less power being drawn on the whole. And we all know how much of a power hog the last gen PS3 was/is. An improved Nvidia graphics processor is also on board, but neither Sony nor Nvidia have revealed any details on the new chip.
