AMD prepares Athlon II X4 CPUs for socket FM2
AMD Athlon brand has been on the market since 1999, when AMD launched seventh generation x86 chips, initially for Slot A and then for socket A. Over its life, there were many variations of Athlon processors. At first, processors from Athlon, Athlon XP, Athlon 64 and 64 X2 families were offered as high-performance chips. When AMD announced Phenom brand, "Athlon" name was repurposed for budget Athlon X2, and later for Athlon II X2/X3/X4 families. The brand didn't die with introduction of A-Series "Llano" Accelerated units in 2011. The Athlon IIs for socket FM1 had the same CPU features as A-Series APUs, but lacked on-chip GPU. Athlon II processors will live on even after transition to upcoming socket FM2. As we recently learned, AMD has in the works three Athlon II processors for socket FM2: Athlon II X4 730, 740 and 750K.
We don't have full details of new Athlon IIs, and we only know a few of their basic features. Athlon II X4 730 and 740 are 65 Watt processors, operating at 2.8 GHz and 3.2 GHz respectively. Athlon II 750K will be clocked at 3.4 GHz, and it may have unlocked clock multiplier. The 750K will have 100 Watt TDP. All three models will be based on "Piledriver" microarchitecture, and have 4 CPU cores and 4 MB L2 cache. We suspect that, like Athlon IIs with "Llano" core, "Piledriver" Athlons will also have on-chip GPU disabled. It's very likely that the Athlon II X4s will support Turbo Core feature, although at this time we don't have information on Turbo Core frequencies. We also don't know when the new products will be released, and whether they will be offered as retails SKUs or not.
