AMD FX is a series of high-end AMD microprocessors for personal computers debuted in 2011, claimed as AMD's first native 8-core desktop processor. The line was introduced with the Bulldozer microarchitecture at launch (CPU codename Zambezi), and was then succeeded by its derivative Piledriver in 2012 (codename Vishera).
One notable feature of the AMD FX microprocessors is that they are all unlocked and overclockable; a feature reserved for the high-end 'k' suffix SKUs from Intel. This allows users to increase the clock speed of their CPU and to gain extra performance out of their product. The FX series are famously more capable of achieving higher clock speeds than their Intel counterparts. In fact, the World record for highest overclock was achieved on an FX-8370, which is clocked up to 8722.8MHz on liquid nitrogen.
- 4 Bulldozer cores within FX-8 series, 3 in FX-6 series, and 2 in FX-4 series.
- Two integer 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.
- All models support up to 4 DIMMs of DDR3 memory.
Unlike the majority of their Intel counterparts, FX chips offer no integrated graphics, a feature reserved to AMD's APU line of processors. Both Zambezi and Vishera use a module design containing two cores on one module.
- AMD later re-used the FX designation for some processors in its socket FM2/FM2+ APU lineup.
