This GPU is based on the same Graphics Core Next architecture as current-generation Radeons, but it employs more advanced power management tech inherited from AMD's Trinity APUs. An on-chip microcontroller manages power states, enabling quicker transitions between a greater number of frequency and voltage states. Thanks in part to that mojo, the 7790 draws 24% less power under load than the Radeon HD 7850 it replaces. The new model also runs two decibels quieter. In games, it delivers lower frame latencies than the 7850 and competing GeForce cards, which translates to smoother gameplay. The 7850 does have higher FPS averages in some titles, suggesting that AMD's recent latency optimizations may not be applied evenly in the latest drivers."
