Most apps will run in an optimized fashion, though you'll need to allow for a 32-bit Firefox if you wish your users to have flash/java plugin capabilities. -Michael Blinn</blockquote><div> If you don't have more than 4GB in your server then just stick with x86. AMD made the x86_64 extensions and called them AMD64. Intels 64bit cpu Itanium (AKA Itanic) sunk. So they were forced to follow AMD lead. They pretty much just copied AMD extensions but called them EMT64. So the smithfield (Pentium D) will run x86 or x86_64. There really isn't much of an advantage to running x86_64 unless you have more than 4GB of ram. 32 bit kernels can also address over 4GB but they have to pay a slight penalty for doing so, whereas x86_64 kernels can do it natively. There are a few extra registers in the cpu x86_64 OS's can utilize but it's not really a big deal. Much more important will be the issues of 32 bit binary only stuff that you will have problems getting to work. (flash is the main one) </div> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Steve Gilmore wrote: > Good Day, > > I'm looking towards using the new Intel P-Dual core ( smithfield > processor) in a supermicro 1u system.
