IBM might be lagging slightly behind the likes of Intel and Microsoft in the 45nm department, but rest assured that a 45nm version of Cell
is in the works and most certainly headed for the PS3. Microsoft told us that 45nm for Xbox was in the works
last year, and Intel is obviously churning out Penryn
chips as we speak, but IBM has finally solidified its own 45nm plans for Cell, and will change over production "soon." The chip will use about 40 percent less power and will be 34 percent smaller than the 65nm version. That means less heat and more reliability, which of course means cost savings for Sony which will (theoretically) be passed on to consumers before too terribly long.
