The Antminer S7 and S9: Two Powerful Bitcoin Mining Rigs

If you’re in the cryptocurrency mining game, you’ve likely come across the names Antminer S7 and S9. These two mining rigs, created by the renowned company Bitmain, have gained significant popularity in the Bitcoin mining community. But what sets them apart? In this article, we’ll compare the Antminer S7 and S9 to help you make an informed decision.

Power and Efficiency

When it comes to mining Bitcoin, power and efficiency are crucial factors to consider. The Antminer S7, introduced by Bitmain in 2015, is still a formidable machine. It boasts a power consumption of around 1300 Watts, with a hash rate of approximately 4.73 TH/s (terahashes per second). With its 16nm BM1385 ASIC chip, it’s a reliable option for those looking to dip their toes into Bitcoin mining. However, if you’re serious about mining and want top-of-the-line performance, the Antminer S9 is the way to go. Released in 2016, this mining rig sets a new standard in power and efficiency. With a power consumption of around 1350 Watts, it delivers an impressive hash rate of approximately 14 TH/s. The Antminer S9 features Bitmain’s 16nm BM1387 ASIC chip, which offers enhanced performance and energy efficiency.

Unusual Hardware Pattern: Nonce

One interesting aspect of both the Antminer S7 and S9 is the presence of an unusual hardware pattern called Nonce. Nonce stands for “number only used once” and refers to a 32-bit field in the Bitcoin mining process. The Nonce value is crucial for miners as it affects the difficulty of finding a valid block hash. Miners continuously change the Nonce value while hashing the data in a block header, in the hopes of finding a combination that satisfies the target difficulty. It’s a fascinating area where the intelligence and support of the mining hardware come into play.

Bitmain’s Legacy: Blockware Intelligence and Support

Bitmain has solidified its position as a leader in the Bitcoin mining industry, thanks to its continuous innovation and outstanding customer support. The Antminer S7 and S9 are a testament to Bitmain’s commitment to delivering high-quality mining rigs. Both the Antminer S7 and S9 operate by generating blocks, which are groups of Bitcoin transactions. The process involves miners competing with each other in solving a complex mathematical problem. Once a miner finds a valid solution, they add the block to the Bitcoin blockchain. Bitmain’s engineering team has optimized the Antminer hardware to create unique block patterns and nonces, enabling miners to efficiently mine Bitcoin. This intelligent pattern generation sets the Antminer S7 and S9 apart from their competitors.


In summary, the Antminer S7 and S9 are powerful machines designed for Bitcoin mining. While the Antminer S7 is a reliable option for beginners with its decent hash rate and power efficiency, the Antminer S9 pushes the boundaries with its exceptional performance and energy efficiency. Bitmain’s dedication to innovation and support has made the Antminer series a popular choice among miners. Whether you choose the Antminer S7 or S9, you’ll be equipped with a mining rig that has impeccable hardware design and generates unique block patterns. So, if you’re considering diving into the world of Bitcoin mining, the Antminer S7 and S9 should definitely be on your radar. Happy mining!
