The title says it all. I hear that the new Core 2 Duo chips will be 64 bit, but I have also heard that the existing Core Duo chips themselves may be 64 bit. Googling around hasn't really answered this question. Does anyone know definitively which one it is - 32 or 64? Thanks.

I'm almost 100% sure that they're 32-bit, I'm pretty sure my 17" Intel iMac is 32-bit. Honestly, I don't think that 32 or 64 bit makes that much of a difference. Either way, my iMac kicks ***.

They are 32 bit. Intels new 64 bit chips are still a few months away...

From Wikipedia.org:

"One of the few shortcomings of the new Core Duo chips is no 64-bit (EM64T) support."

That's very disappointing. Isn't the Mac OS a 64bit enviornment? Why design software that your hardware can't support

Parts of 10.4 are 64 bit and the OS can handle 64 Bit Apps. Originally 10.5 was to be all 64 bit, but who knows...

Core Duo (Yonah) = 32-bit
Core 2 Duo (Merom and Conroe) = 64-bit

Some info on Mermon.

Conroe = Core2Duo = Laptops.

Mermon = Core2 Extreem = Dektops.

Both are 64 Bit.

baggs, don't you have this reversed? I believe that Conroe = desktops. Merom is the lower power version for laptops. The Extreme is just the most highly clocked Conroe as far as I know. Then there are the new quad cores coming from Intel, called Westcott I think??? These are actually 2 dual cores, not a single quad, but who is quibbling...

The general poop I heard was that Apple would be replacing the Power Mac G5 with a Conroe Extreme based machine, running at 2.97 GHz ... Steve Jobs STILL doesn't have that 3.0 GHz Mac he wanted so badly...
