Bitfury began deploying its 16nm ASIC mining chip in mid-2016 with efficiency of 0.06 joules per gigahash and 40 gigahashes per second per chip, advancing mining hardware into a new generation of performance.
Bitfury announced the mass production and deployment of its 16-nanometer Bitcoin ASIC mining chip in mid-2016, claiming a four-fold efficiency improvement over its previous 28nm design. The company declared the 16nm chip "the fastest and most effective" ASIC in the world, achieving 0.06 joules per gigahash—meaning each terahash of computing power required one-third the electricity of competing hardware.
The company announced the chip's December 2015 tape-out after six months of full-custom design work completed in partnership with GUC, a Taiwanese ASIC design specialist. The collaboration gave Bitfury access to advanced semiconductor design expertise while maintaining control over proprietary architecture and manufacturing relationships. Unlike competitors with monolithic vertically-integrated fabs, Bitfury's multi-source approach offered manufacturing flexibility.
Bitfury CEO Valery Vavilov declared: "We are very excited to launch mass production of our super 16nm ASIC Chip. The final results of our hard work have fully met our expectations." Testing confirmed the ambitious specifications: measured engineering samples achieved power efficiency between 0.055 and 0.07 joules per gigahash, hitting the 40 gigahashes per second target. With liquid immersion cooling optimization, single chips could reach 180 gigahashes per second.
The company was immediately deploying the chips into its own mining data centers. Bitfury was in the middle of building a 100-megawatt mining facility in Georgia, and George Kikvadze, Bitfury's CTO, announced the deployment through social media: "The upgrade to 16nm chip technology was underway, signaling continued improvements in production and performance." The move consolidated Bitfury's position as the only major hardware manufacturer also operating large-scale mining operations.
The efficiency delta mattered in a commodity business driven by electricity costs. A mining operation running 10,000 16nm chips consumed roughly one-third the power of equivalent 28nm hardware while generating identical hash output. Over a facility's multi-year lifespan, that power savings amounted to millions of dollars. Miners operating older-generation ASICs faced immediate economic pressure to upgrade.
Vavilov positioned the 16nm launch as environmental leadership: "BitFury is leading the development of environmentally-responsible infrastructure for the next chapter of the Internet based on the bitcoin protocol and blockchain technology." The messaging reflected growing pressure on cryptocurrency mining to address electricity consumption criticism. More efficient chips allowed mining to scale without proportional energy demand growth.
The 16nm transition echoed earlier manufacturing advances—55nm to 40nm to 28nm—each jump doubling performance density. But 16nm represented a harder transition. Older fabs couldn't migrate production; only bleeding-edge facilities supported the new process node. Manufacturing capacity constraints meant delays and premium pricing for the most efficient chips. Bitfury's decision to build its own data centers ensured that first-mover advantage in 16nm efficiency translated directly into mining profitability.
