Expected AM3 (and therefore compatible with AM2 + motherboards), the Athlon X4 II does not have any money and should be followed in 2010 by an Athlon X4 II to 3 GHz, 640.AMD has added in its roadmap, new Athlon X4 II, the 635. Clocked at 2.9 GHz (2.8 GHz cons for the 630 and 2.6GHz for the 620), it uses an architecture similar to other models: it is a processor with four cores, four times of 512 kb Level 2 cache and a TDP of 95 W.Recall that the essential difference between an Athlon and Phenom II II is the lack of L3 cache on the Athlon, which can have an impact on performance.Note states that the AMD Athlon X4 II uses a die Propus, without physically L3 cache (to reduce production costs) but only practice, some models are based on a die Deneb (Phenom X4 II) with the L3 cache is dicedactivated (or bad).
