AMD has adjusted prices for its desktop dual and single-core processors in preparation for the upcoming launch of its Phenom CPUs. In its latest round of price cuts, AMD has knocked off up to 12 percent of its dual-core AMD Athlon 64 X2 processors, while price reduction on several single-core AMD Athlon 64 chips varies from 22 percent to 27 percent, making the Athlon 64 model 4000+ available for $58.

Besides slashing the prices on its already introduced microprocessors, AMD also quietly added two new 45 watt single-core CPUs to its lineup: The 2.4 GHz LE-1620 (1 MB L2 cache, 45 watt), priced at $53 and the 2.2 GHz LE-1600 (1 MB L2 cache, 45 watt), which lists for $47.

The price reductions should drive the firm’s processors deeper into the mainstream and entry-level segment. However, with the transition to next-generation platforms to take place soon, analysts believe this will not affect demand much in the fourth quarter.
