AMD PhenomAccording to industry sources via Tom's Hardware, AMD has decided to modify the naming scheme for their 45-nanometer desktop processors.

While AMD is keeping the Phenom X3 phenom x3 and Phenom X4 branding, model numbers have changed from four digits to five digits in length, causing some confusion. (An example of the lower-end chips is "1xx00" while "20xx0" is for higher end chips.)

Tom's reports that AMD intends to start shipping DDR2 variants of Deneb this year, and that AMD intends to end shipments of the Phenom X4 20550 and 20350 in Q2 2009.

Gavin Steacy postures:

Perhaps AMD are releasing chips with memory controllers which they know function correctly just to get their foot in the door, and are continuing to refine their DDR3 memory controllers in the meantime. It is also possible that AMD have axed the dual memory controller configuration for AM3 CPUs altogether, and these dedicated DDR2-compatible processors are the only means for AM2+ users to upgrade to the 45nm Phenoms without a motherboard and RAM change.

Whatever the reason, Deneb will reportedly switch to AM3 and DDR3 compatibility in H1 2009, with Propus appearing in Q1 as Phenom X4 16x00. We should expect a new range of Phenom X3 processors for the lower end of the spectrum Q2 2009.
