The new bitfury chip will have the same pinout?
Our rev2 55nm chip is in the same 7mm punch-type QFN48 package with identical pinout to the rev1 55nm (summer 2013).
There will be improvement in Ghash/s?
Yes. Our preliminary tests show 25% increase in hashrate and 25% lower power consumption. We will receive new chips tomorrow and will have samples available to developers.
