On Thursday, April 23, Bitcoin’s hashprice stood at $36.46 per petahash per second. That number, logged by hashrateindex.com, measures daily revenue a miner earns per petahash of computing power deployed. At this level, every one of the 14 top-ranked ASIC miners tracked in current profitability data is generating positive daily returns for operators paying $0.04 per kilowatt-hour.
The machines in this group range from $12.73 to $31.62 in daily profit after electricity costs, according to metrics collected by asicminervalue.com. Network difficulty stays elevated, but stronger hashprice and efficient hardware keep margins intact.
Top Performers by Daily Profit
Leading the pack is the S23 Hydro 3U, released in January 2026. Bitmain lists it at 1.16 PH/s with a power draw of 11,020 watts and an efficiency of about 9.5 joules per terahash (J/TH). It requires 380-415 volt three-phase power and operates at around 50 decibels. At $31.62 per day, it sits at the top of the profitability ladder under current conditions.
Close behind is MicroBT’s M79S, released December 2025. It’s rated at 1.35 PH/s with a 20,000-watt draw and efficiency of roughly 14.81 J/TH. Designed for dedicated liquid cooling loops, it returns $29.91 daily.
Bitdeer’s A4 Ultra Hydro, scheduled for May 2026 release, is listed at 886 TH/s with 8,372 watts and 9.45 J/TH efficiency. Once released, it could generate $24.20 per day at current hashprice levels. The company states it sustains output at higher ambient temperatures.
Another April 2026 release, Bitmain’s unit runs at 865 TH/s with 8,650 watts and 10 J/TH efficiency. Its 2U form factor suits high-density rack deployments. Daily profit is estimated at $23.17.
Mid-Range and Older Models Still Profitable
Among older units still ranking, a January 2025 machine rates at 860 TH/s and 11,180 watts. It returns $20.56 daily at $0.04 per kWh.
MicroBT’s M79, released January 2026, outputs 920 TH/s with 14,500 watts and around 15.76 J/TH efficiency. It’s the least efficient hydro unit in the top half, but still yields $19.55 per day.
Block’s Proto Rig, released September 2025, is the only air-cooled machine in the top 14. It runs at 819 TH/s with 12,000 watts. The manufacturer says its nine hashboards are hot-swappable, with on-rack repair times under 90 seconds. It’s also immersion-ready. Daily profit is $18.28.
Bitdeer’s A4 Pro Hydro, coming May 2026, is listed at 680 TH/s with 7,412 watts and 10.9 J/TH efficiency. It would generate $17.62 if available today.
Lower End But Positive
Several other models round out the list with daily returns still in positive territory. The A3 Pro Hydro (September 2025) yields $16.09 at 660 TH/s and 8,250 watts. MicroBT’s M7DS (March 2026) returns $15.91 at 680 TH/s and 9,200 watts. The single-unit S23 Hyd (January 2026) matches the S23 Hydro 3U’s 9.5 J/TH efficiency but produces 580 TH/s, earning $15.81.
The base M7D (March 2026) sits at $14.23 with 634 TH/s and 14.5 J/TH efficiency. Bitmain’s S21 XP+ Hydro (July 2025) earns $12.91 at 500 TH/s and 5,500 watts. Finally, MicroBT’s M73S+ (December 2025) is at the bottom of the table but still profitable at $12.73 per day with 540 TH/s and 13.33 J/TH.
For now, the math works in miners’ favor. Stronger hashprice, efficient hydro-cooled rigs, and low-cost power can keep margins intact even as difficulty holds firm. But this window depends on tight variables: electricity rates, network growth, and of course, Bitcoin’s price. If any shift materially, today’s profitability table can be reordered quickly. Until then, modern ASIC fleets are operating in a rare stretch where scale, efficiency, and timing are aligned.
