PowerPC has had that capability for a long time.
Are all the G5 processors 64bit?
G5's are all 64-bit. nice to know the duo's are too. I didn't know that.
They're 32-bit processors that might (based on that article) have some 64-bit capabilities.
The first question that comes to my mind is what 64 bit instruction set do they have the capability of running? AMD extended the typical x86 instruction set to 64-bits, i.e. x86-64. Intel had originally worked with HP (who owns the remnants of the Alpha via Compaq via Digital) to develop IA-64, which is different from x86-64. Intel calls their IA-64 line Itanium. Depending on which set of instructions the chip can run OS X might not be able to recognize it, etc.
I'd consider them strictly 32-bit processors for the time being, especially since it appears that many of the benefits of 64-bit computing are missing (such as memory capabilities).
the merom, which is the preddescessor to the current duo will be 64-bit.
