AMD pushes new naming scheme
AMD's new naming scheme will start with a letter to indicate the product level; G represents premium product, B represents intermediate product and L represents value product. A second letter will indicate the product's power consumption, with P representing over 65W, S around 65W and E less than 65W, noted Sobon.

The first digit of the proceeding four-digit number will indicate the product family; 1000 represents Sempron/Athlon single-core, 2000 represents Athlon dual-core, 6000 represents Phenom dual-core and 7000 represents Phenom quad-core. The second digit indicates relative core frequencies within the product family while the two remaining digits will be used for the future upgrade functions, pointed out Sobon.
