AMD is planning to harvest lower-grade 32 nm "Trinity" APU chips by branding them as Athlon II X4 quad-core processors, which lack integrated graphics. The chips will be built in the socket FM2 package, supported by future motherboards. As many as three models are confirmed to be in the pipeline.
The new Athlon II X4 chips will be carved out much in the same way as current "Llano" derived socket FM1 Athlon II chips are. Everything on the silicon, except the graphics core is enabled. It means that you need to have discrete graphics handy, when building with these chips, which kind of defeats the purpose of cheap APU-derived CPUs, as socket FM2 motherboards don't come with integrated graphics controllers in the chipset. Among the three Athlon II X4 FM2 parts are:
  • Athlon II X4 730: 2.80 GHz clock-speed, 4 MB L2 cache, 65W TDP
  • Athlon II X4 740: 3.20 GHz clock-speed, 4 MB L2 cache, 65W TDP
  • Athlon II X4 750K: 3.40 GHz clock-speed, 4 MB L2 cache, 100W TDP
Interestinly enough, AMD included an overclocker-friendly model in its lineup. The Athlon II X4 750K ships with an unlocked base-clock multiplier, which makes overclocking a breeze, but that also jacks up its TDP rating to 100W. There's no word on when the products will be released. Source: CPU World
