Don, Core Duo is the lazy way of saying Core Duo 2 or Core 2 Duo. They all refer to the same Intel branded dual core CPU family. Core 2 Duo is the true brand name used by Intel. On the other hand, 'dual processor' (as well as 'dual-core') is a generic term that encompasses ALL CPUs with two cores inside their packaging. If they haven't already, both Intel and AMD will soon release new CPUs with 4 cores in each package. Instead of 'dual core', these (and all subsequent advancements) will have to be called either quad-core (and then oct-core, etc.) or simply multi-core. I'm thinking we'll start seeing the ol' X used in the naming of them. For example, "The all new 16X-core by Intel". Actually, they might get adventurous and call the 16-core version, "The new 4X4". hehe Peace, GMan "The only dumb questions are the ones that are never asked!" ----- Original Message ----- From: "Don WIlcox" <Dwilcox3@xxxxxxxxxx> To: <pctechtalk@xxxxxxxxxxxxx> Sent: Sunday, April 22, 2007 6:44 PM Subject: -=PCTechTalk=- Re: Upgrading to Vista - questions.. > There are various phrases used around modern processors... > > Core Duo > Core Duo 2 > Dual Processor > > I've seen them used in various combinations.
