Following a recent move to speed-bump the Athlon II X2 with the Athlon II X2 255, AMD is planning a similar update for the Phenom II X2 lineup, with the Phenom II X2 555. This model makes it clear that an increment of 5 in the model number indicates bump in default clock multiplier of 0.5X, while that of 10 indicates a full 1.0x increase. Keeping with this trend, Phenom II X2 555 is clocked at 3.20 GHz (16.0 x 200 MHz), a 100 MHz increase. Based on the 45 nm Callisto core, the processor features a total chip cache of 7 MB (2x 512 KB L2 + 6 MB L3), a 4000 MT/s HyperTransport interface, and an unlocked bus multiplier. Expected to be available later this month, the Phenom II X2 555 could carry a price-tag of 80 EUR.
