Computer Processor Codenames: What the processors are and the inspiration behind the names.

In the computer industry there are plenty of buzzwords that get
slung about when talking about the next generation of computer hardware
and CPU codenames are quite possibly the hardest to keep track of due
to the sheer amount of them. We have put together this list with the
codename of each of the existing AMD and Intel processors.

So what is the purpose of all the codenames?
Well, it allows the chip companies to talk about their upcoming CPU’s
without actually talking about them. The chip companies let slip the
barebones facts about the chips, give it a codename and let the
computer hardware geeks speculate and ask questions which makes for
great material to write about in the hardware industry.

Why the weird names? It seems most of Intels
processors codenames are inspired by local geography of the Pacific
Northwest of America. Alaska, Deerfield, Foster, Gallatin, Northwood,
Montana, Madison and McKinley are rivers in Alaska, California,
Montana, Massachusetts and Vermont.

The early series of AMD processors (eg. K5, K6-2) had their name
inspired by Kryptonite which is a fictional element from Superman
comicbooks (Im assuming this was set up to sound like AMD is Intels
kryptonite?). Some of the later AMD series were inspired by sports cars
(eg. Corvette, Mustang). Now that is cleared up, on to the list.
