what will be the hashing speed by chip?
Around 5 GH/s using a 130 nm multi core design @ around 14w total.
ok but the wattage seems too much comparing existing chips
estimate chips price?
It is a fair amount higher then KNC and Bitfury, that much is true. But interestingly enough it is on par with the BFL 65nm first batch, and can be produced at a magnitude lower price once NRE/Dev costs are paid.
