Hi,

I am looking for documents that would describe how many clock cycles 
each instruction takes on the different x86/x86_64 processors. I can't 
seem to find any such documents on AMDs web site or anywhere else.
My CPU is an athlon64 (AMD Athlon(tm) 64 X2 Dual Core Processor 5600+) 
but I would also like to have information about others.

Does anyone know of a good reference?

The AMD docs are called 'Software Optimization Guide':
http://www.google.com/search?q=amd+software+optimization+guide

The Intel ones 'Optimization Reference Manual':
http://www.google.com/search?q=intel+optimization+reference+manual

They have instruction timing lists at the end.

Agner Fog has a document with timing tables as well (manual 4):

Intel and AMD both have some documentation. Google finds it.

"Intel 64 and IA-32 Architectures Optimization Reference Manual"
<http://www.intel.com/Assets/PDF/manual/248966.pdf>
(Appendix C)

"AMD Athlon Processor x86 Code Optimization Guide"
<http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/22007.pdf>
(for K8, Appendix F)

"Software Optimization Guide for the AMD Hammer Processor"
<http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/40546_GH_Optguide_Ver_3-10_2-12-09.pdf>
(for K10, Appendix C)

Thank you!
