How to calculate flops per second
As a previous post says and also wiki, "ivy bridge can do "8 DP FLOPs/cycle: 4-wide AVX addition + 4-wide AVX multiplication" I'm a bit confused here, I know ivy bridge doesn't have FMA, and AVX instruction set can do 4 DP/cycle, so why 4 addition + 4 multiplication?
