Verdict

Bitmain's T-series offers budget-friendly entry into each generation. The T19 served the S19 era, while the T21 is the current-gen economy option.

The T21 is a full generational leap ahead in efficiency. The T19 only makes sense at extremely low purchase prices or for heating applications where raw wattage matters more than efficiency.

Winner: Antminer T21 — Current-generation efficiency at a budget-friendly price point
