It seems to be like this: everything before Core2 will be slower, everything starting with Core2 is faster. Can anyone test the code on an older AMD64? I know there was a change in the way SSE2 instructions are executed in recent architectures.
My Core2Quad (Q6600) slowed down 50%, my i5 improved ~200%, thus I don’t think what you state is accurate. Maybe starting at some specific Core2?
