View Full Version : Are all Dual-core processors 64-bit?

I am pretty confused on which processors are 64-bit and which ones aren't.

I know that all the AMD 64 ... processors are 64-bit (duh!) and I know about the intel itanium and xeon processors that are also 64-bit. But what about all those intel core duos and core 2 duos? what about the pentium D processor? how about any others?

The Core Duo do not have 64-bit support, whereas the Core 2 Duos do.

Pentium, Celeron, Core Solo = 32 bit, single core
Core Duo = 32 bit, dual core
Core 2 Solo = 64 bit, single core
Core 2 Duo = 64 bit, dual core

Celeron = Pentium with less L2 cache (slower)

Centrino = Intel processor, chipset, and wireless card combination (Centrino is *not* a processor)

Oh, and the Pentium D also do. Just check www.newegg.com or Intel's website to see the others.
I'm using a Pentium D 915 right now. :)

Wikipedia is an amazing source for finding general info about processor architecture.
I read maybe 20 articles before upgrading to a core 2 duo in January.
