Antminer S7: “Most Efficient and Powerful” Bitcoin Miner to Date – The Basics about Cryptocurrency

The launch of Antminer S7, the next generation bitcoin miner, was just announced by bitcoin mining ASIC provider Bitmain. According to the company, “this machine is not only our most efficient ever, using less than half the energy per gigahash of the S5, but it is also our most powerful miner to enter mass production.”

Compared to the previous model, the Antminer S7 bitcoin miner is a denser mining rig. The S5 used 60 chips per miner while the Antminer S7 uses 162 of the BM1385 chips.

“It’s true that the S5+ had a greater overall hashrate, but the S7 squeezes more juice from a smaller, more power efficient package,” said Jake Smith, Bitmain’s head of North America, in an interview with Bitcoin Magazine. “When comparing hashrate to weight, size, or power consumption, the S7 comes out ahead.”

“From the BM1385 onwards, we’ll be using full-custom design flow. While full-custom design flow is more work intensive and does have a greater margin of error, it results in greater efficiency, which is where profit can be found,” Smith continued. “It’s difficult to predict the how long our new chip will take to bring to market, but development on our next chip began almost as soon as this one was completed. Our next chip, the BM1387, will be our second full-custom chip, and our first chip built on a 16-nanometer process node.”

Compared to other bitcoin miner providers, Bitmain focuses on selling hardware to the general population. Most other companies have turned their development efforts on creating miners for internal use rather than widespread adoption.

“We’re very strong believers in keeping Bitcoin decentralized. Until recently, most mining was done by so-called average users and not by large mining operations,” Smith explained. “We will continue to make our machines available to Joe Miner for as long as we are making hardware.”
