Over the previous 12 months, application-specific built-in circuit (ASIC) expertise has superior considerably, and this month, Shenzhen, China-based MicroBT launched its newest mining machine boasting an unprecedented hash price of 1,035 terahash per second (TH/s). That is equal to 1.35 petahashes per second (PH/s) of uncooked computing energy.
MicroBT crosses the Petahash Rubicon with new Whatsminer
On the Bitcoin MENA 2025 convention held in Abu Dhabi, UAE, MicroBT introduced the brand new M70 sequence. This machine positions the corporate alongside Bitmain as producers of ASICs able to delivering greater than 1 petahash of SHA256 hashrate.
MicroBT Whatsminer M79S is a water-cooled Bitcoin mining machine that may obtain 1.35 PH/s. This quantity is barely greater than Bitmain’s Antminer S23 Hydro 3U, which generates 1.16 PH/s of hashing energy. At present, no mining machine in the marketplace presents extra full Petahash per second computing energy than these two fashions.
The brand new Whatsminer attracts about 20,000 watts from the wall and has an effectivity ranking of about 14.8 joules per terahash (J/TH). Bitmain’s S23 Hydro 3U is barely much less energy hungry, consuming 11,020W, and its 9.5 J/TH ranking displays a extra environment friendly design.
Its effectivity provides S23 Hydro 3U a slight benefit in present profitability. For instance, on December 18, 2025, Bitmain’s models are projected to generate roughly $33.21 in income per day, in comparison with an estimated $31.76 for Whatsminer M79S, primarily based on fashionable hash value knowledge. Nevertheless, the M79S additionally features a “regular mode” somewhat than an overclocking setting, and when working in that configuration it attracts 14,000W and delivers an effectivity ranking of 13.5 J/TH.
Nonetheless, these two machines are probably the most worthwhile Bitcoin miners out there at this time, marking the forefront of ASIC mining {hardware} as of late 2025, and competing head-to-head for deployment in large-scale industrial mining operations centered on maximizing throughput. This timing coincides with very powerful mining economics, with hash costs hovering close to all-time lows and operators rising their reliance on high-efficiency machines to stay aggressive.
Given its cutting-edge specs, the M79S seems to be appropriate for industrial-scale deployment in 2026. Its arrival coincides with a milestone second for the community, when the hashrate exceeds 1 zetahash per second (ZH/s), equal to 1,000 exahash per second (EH/s). Bitcoin’s hash price will proceed to strengthen as carriers start deploying Petahash-class machines on a big scale.

However for now, miners stay underneath income strain, with on-chain charges contributing lower than 1% of block rewards, and BTC costs slipping into the $80,000 vary by November 2025. Worth will increase haven’t helped miners’ income a lot as far as of mid-December.
In that sense, the M79S and S23 Hydro 3U are extra than simply vainness flexes, they’re a sign of the place mining goes subsequent. As margins shrink and networks transfer deeper into the realm of zettahash, brute power alone can now not carve it out, and effectivity, scale, and deployment self-discipline will now decide the winners and losers.
Within the meantime, one factor is obvious: Petahash class machines are now not theoretical. They’re right here, they’re competing, and they’re quietly rewriting the economics of business Bitcoin mining for 2026.
