The Antminer S21 XP Imm represents the “Extra Performance” tier of Bitmain’s latest generation. While the standard S21 is powerful, the XP model utilizes highly binned chips to achieve energy efficiency levels that were previously considered impossible. Optimized for the SHA-256 algorithm, it is the premier choice for mining Bitcoin (BTC) and Bitcoin Cash (BCH) in industrial immersion environments.
Breaking the 14 J/T Barrier
The standout feature of the Antminer S21 XP Imm 300 TH/s is its efficiency. Operating at a power consumption of 4050W, it delivers a massive 300 TH/s output at a ratio of 13.5 J/T.2 This level of efficiency protects your operation against rising network difficulty and ensures profitability even during market volatility.
Advanced Immersion Cooling Design
By removing the mechanical points of failure-fans-and submerging the unit in dielectric fluid, the S21 XP Imm offers:
-
Enhanced Longevity: Immersion protects the high-grade XP chips from dust, oxidation, and humidity, significantly extending the hardware’s lifespan.
-
Stable Thermal Control: Liquid cooling manages the heat of the 300 TH/s output more effectively than air, allowing for consistent performance without thermal throttling.3
-
Noise-Free Mining: The unit operates in near silence, allowing for high-density deployments in noise-sensitive areas.
-
Low Maintenance: Without air filters to change or fans to replace, maintenance costs are reduced to nearly zero.
