The crisp chill of fall brings change to the seasons and a never ending string of corporate rebranding. AMD is next on the block and rumored to be revising its product roadmap to increase the indentifying model numbers on its upcoming processors from four to five digits. The Phenom X3 and X4 branding will remain, but according to industry sources quoted by Tom’s Hardware , this will also change the AMD product roadmap in some interesting ways. It appears as though AMD is planning to release the Phenom 20550 and 20350 at 3.0 and 2.8 GHZ respectively with a DDR2 memory controller and will be backwards compatible with socket AM2+. This will give users of the previous platform another upgrade path before being forced to replace both motherboard and RAM. Both processors are expected to make a Q4 2008 release but have yet to be confirmed by AMD. All other upcoming processors will likely require DDR3 memory and the new socket AM3.
