Performance and Efficiency#
At ~13.5 J/TH, the M70S uses about 13.5 joules for every terahash it computes. Over a 12 month hold at $0.07/kWh, each 1 J/TH on a machine at a typical 3,500 W draw is worth approximately $158 to $168 in electricity. At its 264 TH/s peak and a typical 3,500 W draw, the M70S's electricity works out to about $0.668 per TH per month.
For operations running large fleets over multiyear periods, J/TH adds up across every unit. Use our profitability calculator to model the M70 and M70S with your expected holding period and BTC price scenarios.
Hosting Suitability#
The M70S is air cooled and compatible with our Southeast Texas facility's standard air cooled racks. Its draw of about 3,140 to 5,000 W, depending on power mode, fits within standard ASIC power supply configurations. No special infrastructure beyond standard ASIC rack deployment is required.
Who Should Buy the M70S?#
- →
- Efficiency focused operators planning a long hold: the 13.5 J/TH rating keeps electricity per TH low over time
- →
- First time miners who want strong long term economics in an air cooled machine
- →
- Fleet operators who want a 13.5 J/TH rating on every unit across the fleet
