t seems that everywhere you go, someone has a different story about the technology that´s inside the new 40 gigabyte PS3 model. There seems to be a bit of confusion over the current state of the Cell processor that powers the console. Is it the original chip that launched with the system, produced with a 90nm fabrication process, or is it a smaller, more efficient chip, produced using a 65nm process?
Today, Sony Computer Entertainment boss addressed the issue directly. In an interview posted at Japan´s Impress Watch, Kaz Hirai confirmed that the new model uses a 65nm process for the Cell chip.
