Tom's Hardware's Optimized GPU/GDDR5 Settings
In addition to recording the performance of each card at stock clock rates and after memory overclocking, we also tried to optimize the GPU/GDDR5 frequencies and GPU voltage to achieve the highest hash rate possible at the lowest power consumption. In other words, we shot for the best possible efficiency in a search for each board's sweet spot.
The table below includes all of the settings we used. Of course, each card is different, so these parameters are specific to our samples. Still, they roughly illustrate what each architecture is capable of.
It's definitely possible to push efficiency even further. For example, you can fight for lower voltages, reducing power consumption at a given clock rate. But your success rate is going to be situational, and largely dependent on luck.
