Bitmain’s upcoming Antminer S23 Hyd 3U, a 1.16 PH/s hydro-cooled ASIC set for a January 2026 launch, has turned petahash-per-rig performance from a rumor into hard specs on reseller pages. Listings and coverage from independent analysts confirm a 1.16 PH/s rating at 11,020 W with 9.5 J/TH efficiency, putting a single rig where full facilities sat a decade ago.
The leap arrives as bitcoin trades around $87,400, roughly 1.3% higher over the past 24 hours, while miners face record difficulty and some of the weakest margins of the cycle. (coingecko.com)
From 860 TH/s To 1.16 PH/s In One Product Cycle
Bitmain spent the last two years walking up a clear curve. The Antminer S21XP Hydro reaches about 473 TH/s at 12 J/TH. (theminermag.com) A later direct liquid-to-chip design built with Hut 8 pushed output to 860 TH/s, a 477,677% jump from the original 0.18 TH/s S1 launched in 2013.
The S23 Hyd 3U takes that curve into petahash territory. Resellers and mining shops list the unit at 1.16 PH/s, 11,020 W, and 9.5 J/TH, with first batches scheduled for January 2026 delivery and preorders already live in late 2025.
Other 2025 workhorses still top out below that level. The current profit leader on many dashboards is Bitmain’s Antminer S21e XP Hydro 3U at 860 TH/s and roughly 11,180 W, which already pulls as much power as several household air conditioners.
Network Hashrate Already Lives In Zettahash Territory
The hardware curve feeds directly into the network. Bitcoin’s hashrate first punched above 1 zettahash per second in April 2025 and then held that level on a seven day average by early September, with Glassnode data cited by multiple analysts.
By October JPMorgan tracked an average monthly hashrate near 1,082 EH/s. Coindesk noted that difficulty reached a record 150.84 trillion in early October after a run of upward adjustments, with hashprice stuck below $50 per PH/s even before the latest price pullback.
Petahash Rigs Raise The Bar For Every Farm
In that environment a single 1.16 PH/s unit is not just a flex. It rewrites farm design. Operators that once budgeted around 100 TH/s boxes now face the choice of retooling around hydro loops and dense rackmount gear or watching their share of blocks grind lower.
Mining firms already operate at these new density levels at the fleet scale. KULR Technology, for example, recently reported 750 PH/s online across 3,570 Bitmain S19 XP 140T machines and targeted 1.25 EH/s by late summer 2025. That kind of aggregate hashrate will eventually fit inside roughly one thousand petahash-class rigs.
“Hash rate is volatile, and even energy markets can shift rapidly. Relying on a single approach risks missing value when market dynamics shift.”
The comment from KULR’s CEO captures the strategic bind. When suppliers push a new ceiling, miners either accelerate capex cycles or accept an ever shrinking slice of network rewards.
Capex, Hashprice And The New Break-Even Math
Petahash rigs land just as economics move against operators. Analyst work from AInvest pegs hashprice falling from around $55 per PH/s in Q3 2025 to below $35 per PH/s by November, with median total hash cost near $44.8 per PH/s. That implies many fleets mine at or below break even.
Tekedia and other research shops describe late 2025 as one of the harshest stretches for miners on record, with bitcoin off roughly 20% from its highs, network hashrate above 1 ZH/s, and transaction fees near multi year lows.
AInvest estimates that payback periods for new hardware have stretched beyond 1,200 days at current conditions. That number assumes current generation kit. Plug 1.16 PH/s into the same model and the daily revenue side improves, but so does the power bill. At 11,020 W, a single S23 Hyd 3U consumes more than many small apartments.
The result is a classic arms race. Large, well capitalized miners that secure cheap power and financing can roll into petahash-class gear and defend or grow share. Smaller shops that still run older S19 or early S21 units face a hard choice. Either stretch balance sheets to chase the new standard or watch zettahash-scale competition dilute their payouts block by block.
