Whatsminer M70 vs M70S vs M73: Full Comparison 2025
All three are MicroBT ASIC bitcoin miners in the Whatsminer M70 series, but they serve different use cases: air-cooled entry-level (M70), air-cooled high-efficiency (M70S), and hydro-cooled high-density (M73).
Our Verdict
Three distinct tiers: the M70 is the entry-level air-cooled option at a lower price; the M70S improves on both hashrate and efficiency for better long-term ROI; the M73 delivers the highest raw hashrate (~470 TH/s) via liquid cooling but is less efficient per terahash than the M70S and requires hydro colocation infrastructure. The M70S offers the best efficiency of the three at ~13.5 J/TH.

Frequently Asked Questions
- Which Whatsminer model is the most efficient?
- The Whatsminer M70S is the most efficient at ~13.5 J/TH, followed by both the M70 and M73 at ~14.5 J/TH. Despite being the most powerful, the M73's advantage is raw hashrate density in a hydro environment, not per-watt efficiency.
- Which Whatsminer model earns the most bitcoin per day?
- The M73 earns the most per day at ~470 TH/s, nearly double the M70S and M70. However, it requires hydro colocation infrastructure and consumes ~7,200W, so operating costs are significantly higher. Use our profitability calculator to compare net earnings.
- Which model is best for home mining?
- The M70 or M70S are the only options suitable for home or small-facility mining. Both are air-cooled and can run on industrial power (200-277V AC). The M73 requires liquid cooling infrastructure and draws ~7,200W, making it unsuitable for home use.
- What is the difference between the Whatsminer M70, M70S, and M73?
- The M70 is the entry-level air-cooled option (214 to 242 TH/s, ~14.5 J/TH). The M70S improves with higher hashrate (226 to 258 TH/s) and better efficiency (13.5 J/TH) at similar power. The M73 is a hydro-cooled unit delivering ~470 TH/s at 14.5 J/TH and much higher power draw (~7,200W), designed for high-density colocation, not air-cooled or home environments.
- Does Fathom Labs offer hosting for all three models?
- Yes. We host all three models at our Texas ERCOT facility at $0.07 USD/kWh all-in, with no performance fees and 24/7 NOC monitoring. Our facility supports both air-cooled (M70, M70S) and hydro-cooled (M73) units.
