Zappykins said: Did anybody else notice that in the Architect Meeting, one of the Microsoft guys said that each CPU will execute six instructions per clock cycle per CPU Core? Sony’s paperwork shows one per CPU per cycle per core. Additional Info: "Some performance numbers were given for the CPU and GPU themselves but these cast more shadow than they do light. Microsoft claimed that each CPU core can perform six operations per cycle. The CPU is believed to be using AMD's Jaguar core, but typically this would only be described as able to handle four operations per cycle; two each of integer and floating point (though even here counting operations is complicated; the floating point operations could use vector instructions such as SSE2, in which case one operation would result in four actual computations, potentially giving eight per cycle for floating point alone)." |
I don't know but each Jaguar core can perform 4 operation per cycle... that how the PS4 CPU works.
