From 90mm to 65mm to 45mm - IBM has announced details on a smaller, more efficient version of the Cell BE processor, which of course is the brains inside every shiny new PlayStation 3. IBM will soon migrate from the 65nm process currently used to manufacture the chips to their next generation 45nm high-k process, which results in a Cell that requires 40 percent less power, reducing cooling costs while a smaller die means higher yields and a lower overall cost. This gives Sony a choice - reduce the price of the system to increase their install base or just ride the cheaper process for awhile to work up a little profit. Also interesting to note is that once again the shrink comes with no performance tweaks, with IBM citing the need to maintain gaming software operation. In other words, IBM's Cell division is Sony's little bitch.
