Over the previous yr, application-specific built-in circuit (ASIC) expertise has superior considerably, and this month, Shenzhen, China-based MicroBT launched its latest mining machine, boasting an unprecedented hashrate 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 New Whatsminer
On the Bitcoin MENA 2025 convention in Abu Dhabi, UAE, MicroBT launched its new M70 collection. The machine locations the corporate alongside Bitmain as a producer providing an ASIC able to delivering greater than a single petahash of SHA256 hashrate.
The MicroBT Whatsminer M79S is a hydro-cooled bitcoin mining machine able to delivering 1.35 PH/s. That determine edges previous Bitmain’s Antminer S23 Hydro 3U, which generates 1.16 PH/s of hashpower. At current, no different mining machines in the marketplace ship a full petahash per second of computational energy past these two fashions.
The brand new Whatsminer attracts roughly 20,000 watts from the wall and carries a acknowledged effectivity score of about 14.8 joules per terahash (J/TH). Bitmain’s S23 Hydro 3U is considerably lighter on energy consumption, drawing 11,020 W, and its 9.5 J/TH score displays a extra environment friendly design.
That effectivity offers the S23 Hydro 3U a slight benefit in present-day profitability. For instance, on Dec. 18, 2025, based mostly on prevailing hashprice knowledge, Bitmain’s unit is projected to generate about $33.21 per day, in contrast with an estimated $31.76 for the Whatsminer M79S. Nonetheless, the M79S additionally features a “regular mode” reasonably than an overclocked setting, drawing 14,000 W and delivering an effectivity score of 13.5 J/TH when working in that configuration.
Even so, the 2 machines stand as essentially the most worthwhile bitcoin miners accessible right now and mark the forefront of ASIC mining {hardware} as of late 2025, competing head-to-head for placement in large-scale industrial mining operations targeted on maximizing throughput. The timing aligns with exceptionally tight mining economics, as hashprice hovers close to all-time lows and operators more and more rely on extremely environment friendly machines to stay aggressive.
Given its modern specs, the M79S seems well-suited for industrial-scale deployments in 2026. Its arrival coincides with a milestone second for the community, which has pushed past a single zettahash per second (ZH/s) of hashrate—equal to 1,000 exahash per second (EH/s). Ought to operators start deploying petahash-class machines at scale, Bitcoin’s hashrate is poised to strengthen additional within the interval forward.

For the second, nonetheless, miners stay beneath earnings stress, with onchain charges contributing lower than 1% of the block reward and BTC costs sliding into the $80,000 vary in November 2025. The value enhance hasn’t actually helped miner income to this point in mid-December.
In that sense, the M79S or the S23 Hydro 3U is much less a conceit flex and extra a sign of the place mining is headed subsequent. As margins tighten and the community pushes deeper into zettahash territory, brute power alone not cuts it—effectivity, scale, and deployment self-discipline now determine winners and losers.
Within the meantime, one factor is evident: petahash-class machines are not theoretical. They’re right here, they’re competing, and they’re quietly rewriting the economics of commercial bitcoin mining heading into 2026.
