Bitdeer's A2 Hydro runs SEAL01 first generation proprietary silicon. 446 TH/s at 7,359W and approximately 16.5 J/TH. The A3 Hydro on SEAL02 (500 TH/s at 6,750W, 13.5 J/TH) replaced it as the current generation with roughly 18 percent better efficiency. The pitch for previous generation hardware is always the same: price. If A2 Hydro units cost 40 to 60 percent less than A3 Hydro, a fleet buyer on cheap electricity deploys more total hashrate for the same capital budget. Ten A2 Hydro units at 4.46 PH/s can outproduce seven A3 Hydro units at 3.5 PH/s on total Bitcoin mined per day, despite the A3 being more efficient per terahash. The breakeven depends on your electricity rate and how long you plan to operate. At electricity below $0.03 per kWh, the daily cost difference between 16.5 and 13.5 J/TH on a single unit is roughly $0.36. If the A2 saves $2,000+ per unit on acquisition, the less efficient hardware recovers its efficiency penalty within months and produces more total hashrate for the remaining deployment. Same 2U hydro rack format at 482 x 665 x 88mm and 20.5 kg. 380 to 480V three phase. 50 dB water cooled. The A2 Pro Hydro (500 TH/s at 7,450W) is the top bin SEAL01 option in the same chassis. Both share water connections with the A3 hydro models for potential mixed generation rack deployments. Bitdeer (NASDAQ: BTDR) designs chips, manufactures hardware, and operates its own mining farms. The A2 generation has a proven operational track record. Ethernet connectivity. 5 to 35 degrees Celsius. Bitcoin, Bitcoin Cash, all SHA 256.
Previous gen Bitdeer SEAL01 hydro. 446 TH/s at 7,359W and 16.5 J/TH. A3 Hydro on SEAL02 (500 TH/s, 13.5 J/TH) is the current generation. A2 competes purely on discounted pricing. Fleet math at cheap electricity: if A2 costs 40 to 60 percent less, more units produce more total hashrate per capital dollar. Efficiency penalty at $0.03 per kWh is roughly $0.36 per unit per day, recovered quickly if acquisition savings exceed several hundred dollars per unit. 2U rack at 20.5 kg. 380 to 480V. 50 dB. A2 Pro Hydro (500 TH/s) also available in same chassis. Compatible water connections with A3 for mixed generation racks. Bitdeer (NASDAQ: BTDR). Ethernet. 5 to 35 degrees. Bitcoin, Bitcoin Cash, all SHA 256. Bitdeer's vertical integration (chip design through mining operations) means the A2 was designed from real production data. Thermal profiles, failure modes, and maintenance access patterns from Bitdeer's own farms informed the hardware design. This production heritage distinguishes Bitdeer from pure hardware manufacturers. 2U rack format. Standard 19 inch cabinets. Water or water glycol closed loop. No dielectric fluid. Compatible with standard hydro mining infrastructure.
Our mining specialists can help you find the perfect miner for your setup and budget.
