MicroBT Launches Whatsminer M70 Series, Raising the Bar for BTC Mining Efficiency
MicroBT, a leading manufacturer of BTC mining hardware, has officially launched its newest generation of ASIC miners, the Whatsminer M70 series. Unveiled at the BTC MENA 2025 conference, the M70 series represents a significant leap forward in energy efficiency and hash rate, intensifying the competitive pressure within the global BTC mining sector. The new lineup is designed to allow miners to maintain profitability, even as network hardy and the industry’s hashprice face historic compression. The release emphasizes MicroBT founder Yang Zuoxing’s belief that the industry’s future growth hinges on continuous improvements in efficiency, rather than being solely dependent on market cycles.
M70 Series: Key Specifications and Efficiency Gains
The Whatsminer M70 series introduces several models tailored to diverse cooling and operational requirements, all optimized for the SHA-256 algorithm used for BTC mining. The key innovation across the series is the dramatic reduction in the Joules per Terahash (J/TH) metric, which is the industry standard for energy efficiency—the lower the number, the better. The series is categorized into three main efficiency classes: the Whatsminer M70 (Entry-Level), achieving an energy efficiency of 14.5 J/TH; the Whatsminer M70S (Standard Efficiency), improving efficiency to 13.5 J/TH; and the Whatsminer M70S+ (Premium Efficiency), setting a new benchmark with an efficiency of 12.5 J/TH. In terms of raw processing power, the air-cooled models deliver a hash rate ranging from 214 TH/s to 244 TH/s. The liquid-cooled and immersion-cooling options, which represent the high-end of the new lineup, offer much greater performance, with models like the M79S, a rack-mounted water-cooled unit, capable of generating up to 930 TH/s. This massive increase in power, coupled with improved energy consumption, forces mining operations globally to immediately evaluate their hardware stacks to remain competitive.
Competitive Pressure and the Race to the Bottom
The launch of the M70 series comes at a critical time for BTC miners, who are navigating an environment of high network hardy and low hashprice. The relentless technological competition among hardware manufacturers like MicroBT, Bitmain, and Canaan focuses on achieving the lowest possible J/TH rating, effectively driving the less efficient, older generation of miners towards obsolescence. The M70 series’ efficiency ratings, particularly the 12.5 J/TH of the M70S+, directly challenge competing flagship models, setting a new industry standard. This “efficiency arms race” compels large-scale mining operations to constantly reinvest in newer hardware to minimize operating expenses, particularly electricity costs, which often account for the majority of a miner’s expenses. Furthermore, MicroBT announced a move into collaborative mining with the introduction of HashSmith as its first partner, a strategy aimed at creating a more comprehensive ecosystem around its hardware.
