It really has been bothering me to find out why low clock cards like mine and Sajin's (USMC's too, albeit you can actually hit 2200 peak) can get higher scores than those that boost 2200+ out of the box. I will say, though, yes, those that do clock higher on average also are the ones getting the ridiculous 15.6k+ scores, however, it seems the theory that higher average clocks directly correlate with higher PR scores is out the window. I hit 15.1k with an average of 2,130mhz, but Soldier is scoring 500 points less with a 2,215mhz average.
It'd also be interesting to know how that translates into something like game fps too. Would the card with average higher clocks or higher PR scores create better frames?
