Considering a bitcoin mining hardware purchase? Make a more informed decision with TGB’s Bitcoin Mining Dashboard.

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.

Bitfury will sell both fully assembled kits and bulk order chips through US (Washington, USA) and EU (Finland) resellers. Pricing will be separated into two batches depending upon expected delivery date with the August deliveries commanding a significantly higher premium than October deliveries. Full kits include a main board, 16 hashing boards, a raspberry pi, and cables to set up the miner. Starter kits include just the same components, but with only 1 hashing board. Additional boards can be bought individually as well.

The ASIC chips passed their first milestone in June when they first demonstrated working test vectors. With the assistance of community members printed circuit boards (PCB), on which ASIC chips are mounted, were completed in late July. The photo below shows the first set of 16 boards attached to a main board along the bottom, with a raspberry pi controller attached to the right.

Bitfury 400 GH/s Miner – currently hashing at 380 GH/s on 16 cards.

It is worth noting as well that 100TH/s, a publicly traded mining company, has partnered with Bitfury to launch a publicly traded company that will utilize the 55nm ASIC chips. The prototype hashing currently in Washington is the first of their 100 TH/s preorder. The company is incorporated in the Marshall Islands but will host equipment in a Washington facility that is operated Bitfury’s US distributor Megabigpower. 100TH/s went public in January, issuing 518,000 shares for 0.04 BTC each with the goal of raising $500,000. Shares are currently trading for around 0.33 BTC, placing them at an estimated market cap of $16,000,000.

    Whats that board hanging off the bottom right? Did some pcb designer forget which way around the connector was supposed to be designed and put it upside down…. awkward!

      Pretty much. They have the wrong L-connector for the board and it ended up sticking the wrong way. It will be be facing upwards and parallel to the other boards in later versions.

    Thanks for the write-up Phillip – a couple clarifications:
    -the prototype is not in Washington, it is with the primary software programmer
    -as of today prototype was hashing at 380Gh/s with all 16 boards. This prototype is hand assembled and has a few chips not responding.
    -weird rPi orientation has been fixed

      Thanks for clarifying this Dave. I updated the hashrate in the article. If you want to send [email protected] an updated picture and the location of the programmer we’ll correct the rest of the article.

    The August kits were sold out. I ordered an October delivery unit.

    Howdy just wanted to give you a quick heads up.
    The text in your post seem to be running off the screen
    in Chrome. I’m not sure if this is a format issue or something to do with internet browser compatibility but I thought I’d post to let you know.

    The design look great though! Hope you get the issue fixed
    soon. Cheers

    Milly where did you order yours from? Are these still relevant in Cost benefit?

      You had to order them months ahead of time from Avalon. I don’t know any companies selling units for immediate delivery that are profitable. That is the problem with buying miners. Companies can mine for themselves so there is no incentive to sell units where the buyer makes a profit.
