That is one of knc's key selling point for knobtune, but what difference does it make if you can hash exactly the same TH on a well designed 28nm?
Whoever suggested a few weeks back they should have just worked on a better 28nm design rather than 20nm was probably right.
i do agree, id rather have a tweaked 28nm now....ah well....if i wanted every single thing the way i like it, i would have started my own company, clearly thats not gonna happen so we depend on knc!
