Hi,
Im looking for the latencies specs of the MOVHPD intrinsic command.
I can find some latency information for most of the other intrinsic commands (e.g. MOVSD) in Appendix C of the "Intel and IA-32 Architectures Optimization Reference Manual" (http://www.intel.com/design/processor/manuals/248966.pdf)
However, I cant find the latency for MOVHPD.

You can find some data in Agner Fog's manuals. For memory operations, I think he gets the round trip times correct, but he may attributeone extra clock to storesand one too fewto loads on Core 2 Duo. I'm not sure about how you could tell the difference in practice, but there is an inconsistency with Intel's documentation set on this count.
