2. Bitmain Antminer S21e XP Hyd 3U
- Hashrate: 860 TH/s
- Power: 11,180 W
- Price: $17,000
- Size: 900 × 486 × 132 mm
Expert insight:
This unit delivers the highest hashrate on the list, but at a steep $17,000. It’s a machine for industrial farms with cheap energy, not for individual miners. Efficiency is strong, but the ROI window is long.

- Hashrate: 500 TH/s
- Power: 5,500 W
- Price: $10,000
Expert insight:
One of Bitmain’s most efficient miners at 11 W/TH. It’s technically impressive, but the high upfront price means only large buyers will see value. For smaller operations, AxionMiner is more attractive.

- Hashrate: 430 TH/s
- Power: 5,590 W
- Price: $11,100

- Hashrate: 480 TH/s
- Power: 8,064 W
- Price: $5,800
