The fx 8320 have 4 ALUs per modules(2 per core = 2 per thread)
4x4 = 16 ALUs
Each modules consist of 2x128bit FPUs or 1x256bit
2x4 = 8x128bit FPUs
i5 4440 have 4 ALUs per core(4 per thread)
4x4 = 16 ALUs.
Each core consist of 2x256bit FPUs or 1x512bit
2x4 = 8x256bit FPUs
ALU stand for Arithmetic Logic Unit
It is the unit for integer instructions.
FPU stand for Floating-Point Unit.
It's for floating points.
Modules is AMD CMT, is having a modules. This modules contains 2 cores. But it's not two complete cores, as they share the fetch, decoder and SIMD execution pipeline.
