Bitmain Launches Antminer S21 Pro 234Th Its Most Advanced Bitcoin Miner
Bitmain continues to push the boundaries of cryptocurrency mining technology with the launch of the Antminer S21 Pro, an upgraded, more powerful, and energy-efficient version of the popular Antminer S21. Designed for Bitcoin (BTC) and other SHA-256-based cryptocurrencies, the S21 Pro delivers an impressive 234 TH/s hash rate while achieving an industry-leading efficiency of 15.0 J/TH.
Compared to its predecessor, the Antminer S21 (200 TH/s, 17.5 J/TH), the S21 Pro offers a 17% increase in hashrate and a 14% improvement in energy efficiency, making it one of the most profitable ASIC miners on the market. Additionally, its enhanced thermal design allows it to operate in high-temperature environments up to 45°C (113°F), ensuring durability and stability in various mining conditions.
The Antminer S21 Pro dominates the SHA-256 mining sector with a massive 234 TH/s hash rate, ensuring higher block rewards and faster mining payouts compared to previous models.
With an unmatched power efficiency of 15.0 J/TH, the S21 Pro reduces electricity costs significantly, maximizing profitability for both small-scale miners and large mining farms.
Unlike many competitors, the S21 Pro is built to withstand extreme temperatures, making it ideal for hot climates and high-density mining operations without performance degradation.
The Antminer S21 Pro is optimized for mining:
Bitcoin (BTC) – The world’s leading cryptocurrency.
Bitcoin Cash (BCH) – A popular Bitcoin fork.
Bitcoin SV (BSV) – Another major SHA-256 coin.
Other SHA-256-based tokens – Ensuring long-term mining flexibility.
Bitmain’s reputation for high-performance, reliable mining hardware continues with the Antminer S21 Pro, featuring advanced cooling, durable components, and optimized firmware for peak efficiency.
