MS doesn't have any published guidance on this. Heck there
guidance is still specific to identical proc to identical proc. Anyone not
running identical procs in DCs and Exchange have to swag it by number of cycles.
But this breaks down when comparing AMD to intel especially when Hyperthreading
is involved and obviously x32 to x64.
Basically you are going into an area where alot of work
hasn't been published so you get to do your own perf tests (which is a good idea
anyway) and come up with a swag and then adjust as necessary in production. If
you already have DCs in a site and don't have scale testnig capability, I
would recommend throwing in an x64 and then start forcing one and then
another Exchange server to use the x64 and watch the loading with perf counters
and SPA2 and don't forget to watch the Exchange counters
too.
