Whatsminer M70 vs M70S — Which Should You Buy?
Both the Whatsminer M70 and M70S are air-cooled ASIC bitcoin miners from MicroBT, compatible with standard mining facilities. The key differences are hashrate, efficiency, and price.
Our Verdict
The M70S wins on both hashrate (226–258 TH/s vs 214–242 TH/s) and efficiency (13.5 vs 14.5 J/TH) at similar power draw (~3,140–3,500W for both). Choose the M70 if upfront price is the primary constraint; choose the M70S for better long-term ROI.

Frequently Asked Questions
- Which is more efficient, the Whatsminer M70 or M70S?
- The M70S is more efficient at ~13.5 J/TH versus the M70's ~14.5 J/TH. This means the M70S produces more hashrate per watt of electricity consumed, resulting in lower operating costs per TH/s.
- Which earns more bitcoin per day, the M70 or M70S?
- The M70S earns more per day due to its higher hashrate (226–258 TH/s vs 214–242 TH/s). At similar power consumption, the M70S delivers more hash for the same electricity spend.
- Can I host both the M70 and M70S at Fathom Labs?
- Yes. Both are air-cooled units compatible with our Texas facility. We host both models at $0.07 USD/kWh all-in — no performance fees, 24/7 NOC monitoring.
- Is the Whatsminer M70 still worth buying in 2025?
- The M70 remains a solid air-cooled miner at a lower price point than the M70S. For deployments where capital efficiency matters as much as operational efficiency, the M70 is still competitive.
- What is the price difference between the M70 and M70S?
- The M70 is listed at $4,980 USD. M70S pricing is available on request — contact us for a current quote.
