Summary
BM1380 is a Bitcoin mining chip developed by Bitmain, a Chinese based IC company. We use the chip to build S1 Dual Blades, nearly a thousand of which has been sold to the Bitcoin community.
BM1380 can run at different mode, depending on the favorite of the users. It can run at 0.75V core voltage and 0.68J/GH high efficiency which can compete with some 28nm mining chips. At 0.75V the hashing board runs without a heat sink. BM1380 is also running at 1.1V or 1.25V voltage sounding reliably, doubling the hash rate and the efficiency spec still better than most of other 55nm node chips on the market.
Now the chip is open for purchase.
About the Chip
Process Node: 55nm
Number of Cores: 8
Package Type: QFN56
Packaged Chip Size: 8 mm x 8 mm
Rated Hash Rate: 2.8GH/s @ 1.1V
