AMD Adds FM1 CPUs Athlon II X4 638 and Athlon II X4 641

The new models 638 (2.7 GHz, 65W) and 641 (2.8 GHz, 100W) integrate 32nm Llano cores with inactive graphics units. AMD is selling both processors for a tray price of $81. In comparison, Intel's cheapest quad-core CPUs are the i5-2390T (2.7 GHz) and the i5-2400s (2.5 GHz) for $184. AMD is riding the value train as $81 buys at Intel just Pentium processors (G850 with two cores and 2.9 GHz for $75, for example).

AMD is offering Athlon II X4 processors also for socket AM3 at 45nm: the 645 (3.1 GHz, 95W, $102) and 640 (3.0 GHz, 95W, $98).
