Update 23/6/2015SF100 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.
Well, it looks like Alpha-T isn't going to get a profitable unit out the door before the competition makes them irrelevant. Good luck with the lawsuits everyone.
There is no price or expected delivery on the SF100 yet nor are you allowed to purchase single units... MOQ of 100 units so I dont think that announcement changes much haha
That's who you're competing against. It will very much matter.
With 0.45W/GHS + 3.8W/MHS, the power efficiency of SF100 is showing really good potential. It is also possible to overclock to certain extent (Sha-256: 2 THS, Scrypt: 55 MHS). Based on recent Bitcoin and Litecoin price, a dual-mode SF100s revenue is similat to that of a to a 2.8-3.2 THS pure Bitcoin miner, which makes it equivalent to 0.3-0.34W/GHS power efficiency when it is dual mining. Taking June 19th price for instance, one SF100 generates 4.2 USD from Bitcoin and 3.8 USD from Litecoin, or a total 8 USD per day (without the costs for electricity deducted).
