The technology we believe AMD to be experimenting with could follow a method more similar to NVIDIA's GPU Boost. There are no definite clock speeds, but ranges, and the boost clock algorithm instructs the driver to alter clock speeds taking into account load, power draw, and temperatures. Close reading of the API documents also reveal that AMD is working on a dynamic boosting technology for the memory clocks
, something that's currently not possible on NVIDIA's products. With AMD GPUs, applying a memory overclock no longer cause the screen to flicker (at least not noticeably).
