In the mainstream, AMD will be adding the FX-6130 to complement its the 6-core FX-6100 and FX-6200 with a 3.9 GHz/ 3.6 GHz version. In the entry level area, AMD is now listing the quad-core FX-4130 with 3.9 GHz/3.8 GHz. Both processors are 125 watt parts.
When released, AMD will be offering a total of eight 32 nm, Zambezi-based FX processors – three quad-core CPUs, three hexacore processors and two eight-core versions – spanning a packed price range from $115 to $245. We would expect AMD to adjust its processor pricing closer to the Ivy Bridge launch as well. The new 4130 model could turn out to be a new budget model as it will only include half of the 8 MB L3 cache of all other FX CPUs.
