You will please notice, Mr. Troll, that the original question was about
Core 2 Duo.
My 'claims' are:
There are no benefits to running intel CPUs (other than Itanium) in
64bit mode. (other than extreme memory requirements which do not impact
today's laptops)
There are definite benefits to running AMD 64bit CPUs in 64bit mode.
Can you describe what the ia32 kernel does and why it is faster
than x86 in some benchmarks?
Again, just for the fun of it, lets ask Dell, the largest purveyor of
intel based platforms if it sells a Core 2 Duo laptop with Windows XP
Professional x64 Edition.
I come up with a blank. How about you?
I'd expect windows to be different. Intel seems to be
saying the enabling EMT64 increases performance for linux
