CPU manufacturers use a Code-names 2

CPU manufacturers use a Code-name for CPU during its development. Once the product is launched, it gets a formal name, which is the name of the current product family. Usually, a new code-name points to improvements in the core, so even if all CPU’s in the product family carry same name, a knowledge of their code names can help identify internal differences.

For Example: Intel Core 2 Duo CPUs have different internal properties corresponding to different code-names.

In The Pipeline:

A few innovations expected in 2008

1. AMD’s quad-core processor for the Desktop, Phenom (not
"Anthlon X4"), was released towards the end of 2007. One can expect to see larger number of these CPUs entering the market.

2. Intel’s "true" quad-core processor for the Desktop market, presently code-named Penryn, featuring four cores on the same die, is expected in 2008. (Intel’s present Core 2 Quad processors are not native quad-core; rather, they fuse two Core 2 Duo Processors.) Penryn is also the first CPU to use the 45 nm fabrication process, the smallest in the industry. Penryn-based CPUs have already been released for the server market, under the Xeon label.

3. DDR 3 SDRAM, presently marketed only by a few high-end memory manufacturers, and supported only by Intel’s P35 Chipset, can be expected to gain broader market acceptance.
