BitFury, the third-largest mining operation by total hashrate, announced in December that it will be mass-producing its custom 16nm ASIC chip and selling the chip directly to consumers.
“Each chip will achieve 40-55 GH/s at the highest possible efficiency of 0.055-0.07 J/GH. From 55 GH/s to 180 GH/s the chop follows nearly linear slop of efficiency from ~0.06 J/GH to 0.2 J/GH,” said Valery Vavilov, CEO of BitFury, in an interview with Bitcoin Magazine . Further, the 16nm chip is capable of running with a power supply voltage of 0.35 V.
The cooling mechanism used with these mining chips is an important factor in determining the maximum hashrate. According to the company’s announcement, for miners using a traditional air cooling setup, the ASIC will be able to reach hashing power of 140 GH/s. However, by using liquid immersion cooling, the chip can reach hashrates of up to 184 GH/s. In October, BitFury announced that it would be using 3M’s Novec 7100 Engineered Fluid for immersion cooling in its data centers.
