Pros & Cons

Bitmain Antminer S21

  • 200 TH/s — strong absolute hashrate for Bitcoin mining
  • Lower acquisition cost than the S21 Pro (~$3,000–3,500)
  • Same chassis and power infrastructure as S21 Pro
  • Less efficient than S21 Pro (17.5 vs 15 J/TH)
  • 3,500 W power draw still requires industrial setup
  • Noise level identical to Pro (75 dB)

Bitmain Antminer S21 XP Hyd

  • Highest single-unit SHA-256 hashrate available (473 TH/s)
  • Same 12 J/TH efficiency as the air-cooled S21 XP
  • Near-silent operation (~45 dB) — noise managed by the liquid loop, not fans
  • Requires Bitmain-compatible Liquid Distribution Unit (LDU) — significant extra cost
  • 5,676 W draw demands serious electrical infrastructure (25+ A at 220 V)
  • High acquisition cost (~$10,000–$14,000 per unit) limits accessibility

Frequently Asked Questions

Is the Bitmain Antminer S21 or Bitmain Antminer S21 XP Hyd more profitable for Bitcoin mining?

Based on hashrate-per-watt efficiency, the Bitmain Antminer S21 XP Hyd is more efficient for Bitcoin mining. However, actual profitability depends on your electricity cost, hardware acquisition price, and coin price — use the live calculator for exact numbers.

What is the power consumption difference between the Bitmain Antminer S21 and Bitmain Antminer S21 XP Hyd?

For Bitcoin mining, the Bitmain Antminer S21 draws 3500 W while the Bitmain Antminer S21 XP Hyd draws 5676 W. The Bitmain Antminer S21 uses 2176 W less power, which at $0.07/kWh saves ~$1334 per year in electricity.

Can both the Bitmain Antminer S21 and Bitmain Antminer S21 XP Hyd mine the same coins?

Yes — both units can mine Bitcoin (BTC) and Bitcoin Cash (BCH). You can switch between these coins with a simple pool configuration change.

Which unit has a better ROI?

ROI depends on hardware acquisition price, electricity cost, and coin price trajectory. The more efficient unit (better J/TH or hashrate per watt) will generally have a lower operating cost per coin mined, but the absolute ROI timeline is determined by the purchase price. Always model both units in the MiningReturns calculator with your specific electricity rate and current market prices.
