Hello guys, sorry for a basic question. I've been looking for architectures which supports FMA. I know Sandy Bridge doesn't support, and Haswel supports it. But, what about Ivy Bridge? Does Ivy Bridge supports FMA?

Best regards.

As Tim said it already Haswell supports FMA instruction.Actually per one core per clock cycle two FMA instructions can be scheduled  for execution.
