Over the previous 12 months, application-specific built-in circuit (ASIC) expertise has superior considerably, and this month, MicroBT, based mostly in Shenzhen, China, unveiled its latest mining machine, with an unprecedented hash price of 1,035 terahash per second (TH/s), equal to 1.35 petahash per second (PH/s) of uncooked computing energy.
MicroBT crosses the Petahash Rubicon with a brand new Whatsminer
On the Bitcoin MENA 2025 convention in Abu Dhabi, United Arab Emirates, MicroBT launched its new M70 sequence. The machine locations the corporate alongside Bitmain as a producer providing an ASIC able to delivering greater than a petahash of SHA256 hashrate.
The MicroBT Whatsminer M79S is a hydrocooled bitcoin mining machine able to delivering 1.35 PH/s. That determine beats Bitmain’s Antminer S23 Hydro 3U, which generates 1.16 PH/s of hashing energy. Presently, no different mining machine in the marketplace affords a full petahash per second of computing energy past these two fashions.
The brand new Whatsminer attracts roughly 20,000 watts from the wall and has a claimed effectivity score of roughly 14.8 joules per terahash (J/TH). Bitmain’s S23 Hydro 3U is considerably lighter by way of energy consumption, consuming 11,020W, and its 9.5 J/TH score displays a extra environment friendly design.
That effectivity provides the S23 Hydro 3U a slight benefit in present profitability. For instance, on December 18, 2025, based mostly on present hash worth knowledge, the Bitmain unit is projected to generate round $33.21 per day, in comparison with an estimated $31.76 for the Whatsminer M79S. Nonetheless, the M79S additionally features a “regular mode” as a substitute of an overclocked setting, consuming 14,000W and providing an effectivity score of 13.5 J/TH when working in that setting.
Nonetheless, the 2 machines are probably the most worthwhile bitcoin miners obtainable in the present day and mark the forefront of ASIC mining {hardware} beginning in late 2025, competing head-to-head for placement in large-scale industrial mining operations targeted on maximizing efficiency. The timing aligns with an exceptionally tight mining economic system, because the hash worth sits close to all-time lows and operators more and more depend on extremely environment friendly machines to stay aggressive.
Given its cutting-edge specs, the M79S seems nicely fitted to industrial-scale deployments in 2026. Its arrival coincides with a historic second for the community, which has surpassed a single zettahash per second (ZH/s) hashrate, equal to 1,000 exahash per second (EH/s). If operators start to deploy petahash-class machines at scale, the Bitcoin hashrate is poised to strengthen additional within the coming interval.

In the meanwhile, nevertheless, miners stay beneath revenue strain, with on-chain charges contributing lower than 1% of the block reward and BTC costs falling to the $80,000 vary in November 2025. The value enhance has not likely helped miners’ earnings as far as of mid-December.
In that sense, the M79S or S23 Hydro 3U are much less of a flex of self-importance and extra of an indication of the place mining is headed subsequent. As margins tighten and the community strikes deeper into zettahash territory, brute pressure alone is now not sufficient: effectivity, scale, and implementation self-discipline now resolve winners and losers.
Within the meantime, one factor is obvious: petahash-type machines are now not theoretical. They’re right here, they’re competing, and they’re quietly rewriting the economics of commercial bitcoin mining heading into 2026.
