That would depend on if they are going to use the 28nm asic they are presently talking about. They could shut down some of the engines in it to make a 50 gh/s unit, but the chip is presently supposed to put out 100 GH/s. The Mercury would be a 1 chip unit at the 100 GH/s rate. If KNC is real, I hope that they will just stick to their present units and not become bogged down with 4 or 5 devices which could slow production.
