Profitability Comparison
Bitmain Antminer S21 official reference
Bitmain Antminer T21 model 10 dual-mode official reference
Based on BTC price of $79,901 and current network difficulty as of Aug 28, 2026. Actual results vary.
Verdict
The T21 is Bitmain's budget entry in the 21-series lineup, sharing the same generation platform as the S21 but at a lower performance and price tier.
The S21 outperforms the T21 in both hashrate and efficiency. However, the T21's lower price point makes it an attractive entry into current-gen mining for budget-conscious operators. The efficiency gap is smaller than in previous S/T generation comparisons.

Frequently Asked Questions
Is the T21 a good budget alternative to the S21?
Yes. The T21 offers current-generation efficiency at a lower price. It is ideal for miners who want modern hardware but have tighter budgets or are testing the waters before committing to the S21.
What is the efficiency difference between the S21 and T21?
The S21 typically runs around 17.5 J/TH while the T21 is around 19 J/TH. This roughly 8-10% gap means the S21 produces the same hashrate using less electricity.
