The line aimed at competing with the Intel Core line of desktop processors, in particular processors based on Sandy Bridge and Ivy Bridge architectures.

FX has been succeeded by the Ryzen brand of CPUs, based on the Zen architecture, which initially launched in 2017 to compete with Intel's later generation processors such as Skylake.
