PS4 is, PS3 or the performance will be up for one. PS3 is the Cell BE, for control of the CPU core "PPU (Power Processor Unit)" the one to each CPU core operation for the "SPU (Synergistic Processor Unit)" the seven (originally eight pieces, for a yield disabled) has a total of 8 CPU cores. Then, Cell BE is a scalable CPU by increasing the number of cores, which can increase the performance architecture.
So, PS4 So, CPU core 32 or the numbers and reach. Cell BE is present, 90nm shrink because of the layout while maintaining its basic version, the smaller the degree of reduction of the die. 235 square mm for the 90nm version, 65nm version is 175 square mm, 45nm version is 115 square mm. However, PS4 again to fix the design of a significant number of 45nm chips on the CPU cores can be (SPU Toshiba has significantly reduced the area of core). SCE’s original "IKEIKE" Under the plan, 45 ~ 32nm in the 24 core and 32-core Cell BE and had potential. As if Moore’s Law, 32 reach the core. But SCE will probably do so.
