Product Details

Bitmain Antminer K7 63.5TH Eaglesong Miner for Maximum Nervos CKB Mining Output

Top bin K7. 63.5 TH/s from the best Eaglesong chips Bitmain produced, drawing the same 3,080W as the standard bin (58 TH/s). Nine and a half percent more CKB mining output for identical electricity cost. The most productive Nervos CKB miner from any manufacturer at any tier. At 48.5 J/GH versus 53.1 J/GH on the standard bin, the top K7 is meaningfully more efficient. Over a year at $0.07 per kWh, the efficiency advantage saves roughly $0.48 daily versus the standard bin. Small per day, $175 per year per unit. More importantly, the top bin mines 9.5 percent more CKB tokens that may appreciate independently of electricity costs. Same universal 100 to 240V. Same 75 dB. Same 3,080W. Same… firmware. Same everything except the silicon. If your distributor offers both bins, the top bin at less than 9.5 percent premium is the automatic choice. At more than 9.5 percent premium, the standard bin produces more CKB per dollar invested. Research Nervos CKB ecosystem before purchasing either bin. CKB token value, exchange liquidity, developer activity, and Layer 2 adoption determine whether mining Nervos is a sound investment. The hardware is excellent. The economic case depends on the blockchain. 430 x 195 x 290mm at 16.1 kg. 100-240V input. Ethernet. 5 - 45 °C. Bitmain firmware. Daily electricity at $0.07 per kWh: $5.17. Monthly: $155. Compare against Nervos CKB revenue at 63.5 TH/s and current difficulty.
