AMD "Hawai" compute performance extrapolation

Here is a graph of the theoretical peak performance of current top AMD GPUs. These include the Tahiti GPU known from the HD-7970 and the soon to be released Hawai GPU as the heart of the AMD R9-290X and R9-290. In this extrapolation each compute element in the GPU is supposed to perform 2 floating point operations per clock which is 1 MAD (multiply-add) operation per clock.

Each vendor will probably provide different cards operating in different frequencies so this diagram could be helpful for anybody who intends to by a new card for compute.
