Sony has revealed more details at ISSCC on their 65nm SOI Cell Broadband Engine that are in mass production now to replace the 90nm Cell processors in the current PlayStation 3 units selling out there. The 65nm Cell B.E. die size is smaller as compared 90nm thus it is cheaper to produce and emits lesser heat. Also the SRAM on 65nm Cell B.E is improved with a new array supplied by 2 separate voltages with a boost in performance and power consumption. Sony engineers managed to run the 65nm Cell B.E. chip at 6GHz with just 1.3V. Sony is expected to continue using Cell B.E. architecture into their next generation PlayStation 4 and there is a possibility that IBM’s eDRAM technology will be employed.
