"Although some may think these are nothing more than high binned chips, AMD has tweaked these for both performance and power consumption. All 3 CPUs offer 8 cores, and with the lower TDP can be used on mid-range motherboards. This allows users already running an old FX 4XXX or 6XXX on a mid-range 970 or 990 motherboard a simple upgrade path to 8-cores."
