core is a native 64bit architecture.
Uhhh . . . no. It's EM64T technology.
Conroe and EM64T
Thanks to both of you for posting. But WiseCracker, what do you mean?The x86-64 architecture (which AMD created) provided for the use of 32-bit and 64-bit extensions to the x86 32-bit nee 16-bit nee 8-bit architecture.. EM64T is the Intel adaptation of AMD64.
"True" 64-bit processors include the Alpha (RIP), PA-RISC and the *I-Tanic* (heh heh) listed above. When the I-Tanic1 first set sail there were great hopes that it would bridge the 32-bit/64-bit divide but, of course, it sunk . . .
What all this poo-poo is about is that processors have *registers*. The x86-64 architecture doubled the number of general registers and SIMD registers.
The 8 general registers in x86 could only handle 32 bit values. x86-64 provides for 16 general registers and 64 bit values.
32 bit hit the memory ceiling at 4gb and Windoze effectively splits this at 2gb for the OS and 2gb for apps. Prior to WinV the only MS operating systems with >4gb RAM were Win Server03 and WinXP Pro64.
In your lifetime you will not hit the memory ceiling with the x86-64 ISA and a 64-bit OS.
With the Core2 Intel took x86-64 and kicked AMD's ass with it. Intel loaded up the cache and beefed up SSE utilization. How well AMD will return the favor to Intel is the subject of great debate on this forum.
AMD's K10 will greatly expand SSE utilization. To the extent it allows them to catch up or surpass Intel is the $64 million question.
To add fuel to this fire (LOL) I think the *Mean Green* is sandbagging (like they did with the Opteron in 2003). Intel will soon lose all of it's business to AMD and have to close their doors by mid-2008 . . . :roll:
And I think you could set up a *dual-boot* if you really wanted to check out a 64-bit OS. Be prepared and do your homework . . . .
