SF100－the first 28nm Dual-Mode Miner is getting into mass production

With the experience of developing dual-mode chip and miner manufacturing succeeded from Gridseed, Sfards Technology has successfully developed and produced the first FD-SOI 28nm SHA-256 (Bitcoin) and Scrypt ( Litecoin ) dual-mode mining chip SF3301, in massive scale. After more than one month evaluating, prototyping, and extreme-condition pressure testing, the first 28nm dual-mode miner, SF100, is about to be produced massively.

SF100 dual-mode miner has 24 SF3301 chips, with the running modes as following:

Dual mining mode, Bitcoin hashing power 1700 GHS + Litecoin hashing power 47 MHS, the power consumption at wall of whole miner is 960W.
Bitcoin single mining mode: Hashing power 1700 GHS, power consumption 770W.
Litecoin single mining mode: Hashing power 47 MHS, power consumption 180W.

With 0.45W/GHS + 3.8W/MHS, the power efficiency of SF100 is by far the best in the market. It is also possible to overclock to certain extent (Sha-256: 2T, Scrypt: 55M).

The unique ability of dual-mode mining makes SF100 the best choice of mining community. It offers more choices to dig potentials not only of Bitcoin, but also of Litecoin and other altcoins. For fiat currency investors, dual-mode is good for them because SF100 maximizes their profits; for Bitcoinfundamentalists, its also preferable since the altcoin revenue helps them to cover the power cost of mining Bitcoin.

Based on recent Bitcoin and Litecoin price, a dual-mode SF100s revenue equals to a 2.8-3.2T pure Bitcoin miner, which makes it 0.3-0.34W/GHS power efficiency. (Take June 19th price for instance, one SF100 generates 4.2 USD from Bitcoin and 3.8 USD from Litecoin, in total 8 USD per day).

Sfards Technology will be selling SF100 to public on July; the first batch quantity is limited. The SF3301 chip will be available for sale on August.
