Hammer can run 32, mixed 32/64, or pure 64. ...if it ever gets OS support... it sure won't do that under current versions of any OS... I'll go on record and say that the hammer series will never be a competitive threat to IA-64. It will be competition for future P4 chips, but not IA-64...

Dan, Itanium/McKinley runs only 32 or 64. Unless you are going to give up all possibility of using the 64 bit execution units of Itanium/McKinley (not a bad idea unless/until there is some software for it) it may be that you can't use the 32 bit hardware in Itanium/McKinley. You don't think that Itanium will have a mode under which Windows 64 would be able to start 32bit app and use hardware 32bit portions of Itanium to run it? Joe

Dan, <Well, keep in mind that Itanium/McKinley doesn't support 3 modes like hammer. Hammer can run 32, mixed 32/64, or pure 64. Itanium/McKinley runs only 32 or 64. Unless you are going to give up all possibility of using the 64 bit execution units of Itanium/McKinley (not a bad idea unless/until there is some software for it) it may be that you can't use the 32 bit hardware in Itanium/McKinley.> Try again. Itanium's two modes of operation work just like the Hammer 32/64 and 64 modes (using your terminology). The only thing Itanium doesn't support is a mode that resembles Hammer's 32-bit legacy mode (i.e. run a 32-bit OS). You also forgot to mention that in order to use Hammer's 32/64 and 64 modes, you actually need a 64-bit OS. So far, Hammer's 64-bit OS support is vapor-thin. Tenchusatsu
