Bitmain and Antminer: History, Evolution, and Best Models
The history of Bitmain and Antminer is inextricably tied to the history of Bitcoin mining itself. From its humble beginnings in 2013 to becoming the undisputed giant of the mining hardware industry, Bitmain has repeatedly revolutionized the landscape with innovations that have set standards and shaped the decentralization of the Bitcoin network. This historical journey takes you from the first Antminer to the impressive latest-generation equipment of today.
The Origins of Bitmain
Founding and Early Years (2013–2014)
Bitmain Technologies Ltd. was founded in 2013 in Beijing, China, by Micree Zhan (the technical genius behind the chips) and Jihan Wu (the business strategist). Their mission was clear: create specialized hardware for cryptocurrency mining that would far surpass the efficiency of GPUs.
The first product, the Antminer S1, launched in December 2013, marked the beginning of a new era. With 180 GH/s and 360W power consumption, it was revolutionary for its time, though it seems insignificant compared to modern equipment.
| Model | Year | Hashrate | Power | Efficiency |
|---|---|---|---|---|
| Antminer S1 | 2013 | 180 GH/s | 360W | 2000 J/GH |
| Antminer S2 | 2014 | 1 TH/s | 1,100W | 1100 J/GH |
| Antminer S3 | 2014 | 441 GH/s | 340W | 771 J/GH |
| Antminer S4 | 2014 | 2 TH/s | 1,400W | 700 J/GH |
| Antminer S5 | 2014 | 1.15 TH/s | 590W | 513 J/GH |
The Era of SHA-256 Dominance (2015–2017)
The S7 and S9 Revolution
The Antminer S7 (2015) and especially the Antminer S9 (2016) cemented Bitmain’s dominance in the market. The S9, with its 16nm manufacturing process, was an absolute game-changer.
Antminer S9: The Legendary Unit
| Specification | Value |
|---|---|
| Hashrate | 13.5 TH/s |
| Power | 1,323W |
| Efficiency | 98 J/TH |
| Process | 16nm |
| Operational life | 2016–2022 (6 years) |
The S9 remained profitable for nearly 6 years, something unthinkable in the technology industry. Many S9 units still operate in regions with extremely cheap electricity.
| Model | Year | Hashrate | Efficiency | Process |
|---|---|---|---|---|
| S7 | 2015 | 4.73 TH/s | 250 J/TH | 28nm |
| S9 | 2016 | 13.5 TH/s | 98 J/TH | 16nm |
| T9 | 2016 | 12.5 TH/s | 125 J/TH | 16nm |
| R4 | 2016 | 8.7 TH/s | 126 J/TH | 16nm |
| S9i | 2018 | 14 TH/s | 93 J/TH | 16nm |
Innovation and Competition (2018–2020)
The 7nm War
With the arrival of competitors like MicroBT (Whatsminer) and Canaan (AvalonMiner), Bitmain responded with the S17 series and subsequently the S19, using 7nm manufacturing processes.
Evolution of the S19 Series
| Model | Year | Hashrate | Efficiency | Process |
|---|---|---|---|---|
| S17 | 2019 | 56 TH/s | 45 J/TH | 7nm |
| S17 Pro | 2019 | 62 TH/s | 39.5 J/TH | 7nm |
| S19 | 2020 | 95 TH/s | 34.2 J/TH | 7nm |
| S19 Pro | 2020 | 110 TH/s | 29.5 J/TH | 7nm |
| S19j Pro | 2021 | 104 TH/s | 29.5 J/TH | 5nm |
| S19 XP | 2022 | 141 TH/s | 21.5 J/TH | 5nm |
The S19 series was the industry standard during the 2020–2023 era, with the S19 XP being particularly notable for achieving sub-25 J/TH efficiency.
The Modern Era: S21 and Beyond (2023–2026)
Antminer S21: The New Gold Standard
Launched in November 2023, the Antminer S21 represents the leap to 3nm processes, achieving the historic milestone of 15 J/TH efficiency.
| Variant | Hashrate | Power | Efficiency | Approx. Price |
|---|---|---|---|---|
| S21 (200T) | 200 TH/s | 3,500W | 17.5 J/TH | $3,500 |
| S21 (234T) | 234 TH/s | 3,510W | 15.0 J/TH | $4,200 |
| S21 Pro (335T) | 335 TH/s | 5,360W | 16.0 J/TH | $6,500 |
The Significance of Each Nanometer
The evolution of manufacturing processes has been the engine of efficiency improvement:
| Generation | Process | Best Efficiency | Year |
|---|---|---|---|
| 1st Gen | 55nm | 2000+ J/TH | 2013 |
| 2nd Gen | 28nm | 250 J/TH | 2015 |
| 3rd Gen | 16nm | 98 J/TH | 2016 |
| 4th Gen | 7nm | 39.5 J/TH | 2019 |
| 5th Gen | 5nm | 21.5 J/TH | 2022 |
| 6th Gen | 3nm | 15.0 J/TH | 2023 |
