AMD FX is a series of high-end AMD microprocessors for personal computers. According to AMD's website, the FX-series is the industry's first native 8-core desktop processor.[1] The FX-series is based on the Bulldozer microarchitecture and its derivative Piledriver, which use a module design which contains two cores on one module.


  • All AMD FX microprocessors are unlocked and overclockable.
  • Two Integers-Clusters (seen as logical cores from OS) in each Bulldozer "Core".
  • All models manufactured from 8 logical cores with simple OROCHI die production, in 938 pins µPGA package AM3+ socket.
  • 4 Bulldozer cores within FX-8 series, 3 in FX-6 series, and 2 in FX-4 series.
  • All models support up to 4 DIMMs of DDR3 1866/2133 memory.
