Comparing the Antminer S21 and T21: A Guide for Bitcoin Miners

When it comes to Bitcoin mining hardware, the right equipment can significantly enhance profitability. Today, let's look at two popular models from Bitmain: the Antminer S21 and Antminer T21, and help you decide which might be the better choice for your mining needs.

?? Antminer S21 Overview: The S21 series comes in three variants: 200T, 195T, and 188T, all boasting an impressive efficiency of 17.5J/T. A notable upgrade for this model is the inclusion of a P13-C20 power cord, designed to operate between 220V to 277V. This adjustment means the S21 not only offers high performance but also comes ready to plug in, a convenience not seen in earlier Bitmain models.

?? Antminer T21 Overview: On the other hand, the T21 features a hash rate of 190T at a standard energy efficiency of 19J/T and requires a higher voltage range of 380V to 415V. It utilizes a P33-P33 power cord and needs a specialized PDU for operation. Unique to the T21 is the HEM mode, which under optimal conditions (operating temperatures below 30°C), boosts the hash rate to 230T while increasing power efficiency to 22J/T.

Key Differences:

• Power Efficiency: The S21 is more energy-efficient, making it a preferable option for miners who are particularly concerned about electricity costs.
• Voltage Requirements: The T21’s higher voltage requirements and the need for a specific PDU interface may pose a challenge for some miners, especially those without access to industrial-grade power setups.
• Cost and Performance: The T21 is generally less expensive and offers the ability to automatically overclock, achieving higher hash rates without the need for power supply upgrades.

Conclusion: The T21 might be more suited for professional miners who can meet its more demanding electrical setup and benefit from its overclocking capabilities. Meanwhile, the S21's lower power consumption and compatibility with residential voltage make it an excellent choice for home miners looking for high efficiency and ease of setup.

Choose wisely, and may your mining endeavors be profitable!
