With respect to Neptune we are where we intended to be at this stage and are still contemplating aspects of the design. Understand that the approach is not the same as that of Jupiter. 28nm was extremely disruptive at the time, of which the effect can plainly be seen. Hashrate was given priority to power consumption, and safety and speed to market even more so, but going forward and acknowledging that power consumption becomes more a critical factor the Neptune has to be created as more a long term solution. We will not skimp or rush the design here. This does not mean I'm indirectly verbalising a delay, so don't go looking for hidden meanings, there aren't any to find, just rest assured I'm stressing we value the integrity of the design more which is why Q1/Q2 was given to ensure that margin is present so we commit the best foot going forward in what is uncharted waters within bleeding edge silicon. We're not rushing the design at the cost of it's ability to function, and function well. The sha-256 implementation is actually relatively simple, but there is still quite a bit we can optimise to remain competitive for you and us.
