Compare Bitmain Antminer Z11 vs Bitmain Antminer S21+

The Bitmain Antminer Z11 generates higher daily profit of $4.07 compared to $0.27 from the Bitmain Antminer S21+. This superior profitability comes from its optimized power-to-hashrate ratio and current electricity costs at $0.080 per kWh. The Bitmain Antminer S21+ consumes 3712W versus 1418W for the Bitmain Antminer Z11, resulting in $4.40 higher daily electricity expenses. This power difference becomes particularly important for large-scale mining operations where every watt counts toward overall facility efficiency and cooling requirements.

Release timeline shows the Bitmain Antminer Z11 launched in April 2019 while the Bitmain Antminer S21+ entered the market in June 2025. Newer miners typically incorporate improved chip architecture and manufacturing processes, leading to better efficiency and performance characteristics. Physical dimensions comparison reveals the Bitmain Antminer Z11 measures 134 x 242 x 302mm while the Bitmain Antminer S21+ has dimensions of 400 x 195 x 290mm. Size considerations directly impact rack density, shipping costs, and facility space requirements for mining operations. Acoustic performance differs with the Bitmain Antminer Z11 operating at 70db versus 75db for the Bitmain Antminer S21+. Noise levels significantly impact placement options, with quieter units suitable for residential or office environments while louder miners require dedicated facilities with proper sound isolation. Humidity specifications indicate the Bitmain Antminer Z11 operates within 5 - 95 % conditions compared to 5 - 95 % for the Bitmain Antminer S21+. Better humidity tolerance enables deployment in more diverse geographic locations and reduces the need for expensive climate control systems in mining facilities.
