Aug 2, 2013 Posted By Phillip Archer. After almost a full year of development and one month of delays, BitFury’s ASIC bitcoin mining prototype has begun hashing at 400 GH/s. Application specific integrated circuits (ASIC) are customized chips that perform bitcoin mining calculations. While there have been a couple companies releasing ASIC miners (Avalon, ASICMiner, Butterfly Labs), there is significant room for improvement within the technology itself. With hundreds of units expected to land in Europe and the Americas this month, Bitfury products represent the most advanced chips to hit mass production and will significantly change the bitcoin mining landscape.

BItfury ASIC chips use a 55nm process and are sold running at an estimated 1.56 GH/s per chip, with demonstrated performance up to 2.7 GH/s. Although they are clocked slower than Butterfly Lab’s 4 GH/s chips, they will run 4x more efficiently at 0.8 Watts/Ghps. Power efficiency will be a deciding factor in a bitcoin miner’s longevity as profitability narrows with increasing difficulty. - Read more here:
