Сравнение Antminer S21 и T21: выбор подходящей машины для майнинга биткоинов

As the most popular Bitcoin mining machines on the market, the Антмайнер S21 и Т21 have become the top choices for Bitcoin miners. However, many miners are still hesitant between the two models because of their different specifications, and they are unsure which one is the right fit for them. Therefore, the MinersKing team has prepared this article to compare the Антмайнер S21 и Antminer T21 in various aspects, helping you find the most suitable mining machine model.

Антмайнер S21  

Antminer S21 series consists of three models: 200T, 195T, and 188T, all of which boast an impressive efficiency of 17.5J/T. A significant upgrade for this model is the adoption of the P13-C20 power cord, which can operate within a voltage range of 220V to 277V. This means that the С21 not only provides high performance but also allows for direct plug-in usage. It’s worth noting that this feature was not available in previous Bitmain models, highlighting the increasing user-friendliness of the С21 for miners.

Antminer T21

Antminer T21 has a hash rate of 190T and a standard energy efficiency of 19J/T, requiring a higher voltage range of 380V to 415V. It uses the P33-P33 power cord and requires a specialized PDU for operation. The unique feature of the T21 is the HEM mode, which, under optimal conditions (operating temperatures below 30°C), can boost the hash rate to 230T while increasing power efficiency to 22J/T. The ability to overclock is also a deciding factor for many miners.

Ключевые различия

Efficiency: The Антмайнер S21 has higher efficiency, making it a better choice for miners who are particularly concerned about electricity costs.

Требования к напряжению: T21 имеет более высокие требования к напряжению и требует специального интерфейса PDU, что может представлять проблему для некоторых майнеров, особенно для тех, у кого нет доступа к промышленным системам питания.

Cost and Performance: The Антмайнер S21 tends to have a higher market price, while the Т21 is generally more cost-effective. Additionally, the T21 offers the advantage of automatic overclocking, allowing for increased profitability without the need for power supply upgrades.

Заключение

Antminer T21 is more suitable for professional miners who can meet its higher electrical setup requirements and benefit from its overclocking capabilities. If you are a home miner, we would recommend choosing Antminer S21 because of its lower power consumption, compatibility with residential voltage, and ease of installation.
