I realise this may be a 'schoolboy' question, but I've looked on the net for ages and can't find an answer, can anyone help?!? preferably with a link to a page that confirms the answer.
myself and a few colleagues remember hearing that a major advantage of AMD's 64bit CPU's was that they could run 32-bit OS and apps without needing to 'emulate' whereas the Intel ones couldn't.
Is this still the case? was this only ever the case for desktop processors? (We're looking at this from a server perspective). will a server with a Xeon 64bit processor HAVE to have 64-bit Win Server 2003 installed? or will it run 32bit Server 2003... also, if 32bit apps are run on it, will there be a performance hit (due to emulation) as opposed to running them on a 32-bit processor-based server?
Many thanks for your help! :-)
