Then you should contact XFX tech support for them to explain the difference, AMD supplies basic chip/board to aftermarket makers who then may make additions/alterations to the base specifications as well as using different component models (usually within AMD spec.) such as caps/mosfets/pwm/etc......, also some make/models have their own better cooling.
This is why you see different makes/models with varying specs/performance in benchmarks etc..........
