"AMD has recently changed its CPU numbering scheme plans from five digits number to only three digits, similar to that of Intel's Core i7 CPUs, according to sources at motherboard makers.

AMD's upcoming Phenom X4 20350 and 20550 CPUs will be renamed to Phenom II X4 920 and Phenom II X4 940 Black Edition, respectively. The launch date of the products will also be delayed from November this year to during CES 2009 in January next year.

The company's 45nm AM3-based CPUs will also be renamed to the Phenom II X4 900, X4 800 and X3 700 series, and will launch in the second quarter of next year. AMD is also planning to launch a quad-core high-end CPU, Phenom II X4 945 Black Edition, in the second quarter next year along with the Phenom II X3 600 and Phenom II X2 200 series."
