Conclusion
The choice between Bitmain Antminer T21 and NerdMiner NerdOCTAxe is a classic dilemma for mining investors. The unified algorithm (SHA-256) allows switching between coins (Bitcoin, Fractal Bitcoin, BitcoinSV, Bitcoin Cash, Terracoin, Namecoin) on both ASICs, but maximum profit is currently achieved when mining Bitcoin, Fractal Bitcoin. Bitmain Antminer T21 has several versions, with hashrate starting from 180Th and going up to 190Th. Model NerdOCTAxe from manufacturer NerdMiner is a unique solution with 9.6Th power, available in a single version. The difference in 180.4 Th shows the advantage of one model, but it's also worth paying attention to the efficiency of the models. Model Antminer T21 has an efficiency of 19 j/Th and NerdOCTAxe has 16.67 j/Th. The power consumption of Bitmain Antminer T21 190Th is 3610 Watts. NerdMiner NerdOCTAxe 9.6Th, in turn, consumes 160.032 Watts. The cooling type for both models is identical — classic fan airflow.
