What hashrate does the A4 Ultra Hydro deliver?

886 TH/s SHA-256 at 8,372.7W continuous and 9.45 J/TH efficiency. Bitdeer's ±10 percent hashrate tolerance produces real world output between 797 and 975 TH/s. ±5 percent power efficiency tolerance produces real world efficiency between 8.98 and 9.92 J/TH. Bitdeer specifies "consistent 870 to 900 TH/s" range under typical operating conditions.

What makes the SEAL04 chip unique?

SEAL04 is Bitdeer's fourth generation proprietary SEAL series Bitcoin mining chip, manufactured using advanced process nodes through TSMC partnership. Generational improvements: SEAL01 in original A1 series, SEAL02 in A2 family at 14.9 to 16.5 J/TH, SEAL03 in A3 family at improving efficiency, SEAL04 in A4 family at 9.45 to 10.9 J/TH. The A4 launch marks the successful fulfillment of Bitdeer's previously announced multi year SEALMINER technology roadmap.

What does breaking the 10 J/TH barrier mean?

The A4 Ultra Hydro is the first production Bitcoin miner to operate below 10 J/TH efficiency at scale. Competitive context: Bitmain S23 Hydro at 9.5 J/TH (just above), S21 XP+ Hyd at approximately 12 J/TH, MicroBT M70 family at 18 to 19 J/TH. At 100 unit fleet scale, the efficiency advantage versus 12 J/TH alternatives represents approximately 21 percent reduction in continuous power draw at equivalent hashrate output, translating to substantial annual electricity savings at industrial rates.

2U rack mount chassis at 482 x 665 x 86 mm and 20.5 kg. The 86 mm chassis height corresponds to 2U in standard 19 inch rack measurement. Same dimensional standard as the Bitdeer A2 Pro Hydro, A3 Hydro, A3 Pro Hydro, and A4 Pro Hydro, allowing operators with existing Bitdeer hydro infrastructure to drop A4 Ultra Hydro units into existing rack slots without facility reconfiguration.

Jak se srovnávají A4 Ultra Hydro s A4 Pro Hydro?

A4 Pro Hydro at 680 TH/s, 7,412W, and 10.9 J/TH. A4 Ultra Hydro at 886 TH/s, 8,372.7W, and 9.45 J/TH. The Ultra Hydro delivers approximately 30 percent more hashrate at approximately 13 percent better efficiency per terahash and approximately 13 percent more power draw. Both share the same SEAL04 chip platform with the Ultra Hydro using better binned chips and tighter cooling tolerances. For operators choosing between A4 hydro tiers, the Ultra Hydro delivers the flagship efficiency and hashrate; the Pro Hydro delivers a lower acquisition cost entry into the SEAL04 platform.

Jaké napětí je potřeba?

380 to 480V three phase industrial AC input with up to 97 percent PSU efficiency. Frequency range typically 47 to 63 Hz. Not available in residential or most light commercial settings. Purpose built for professional mining facilities with three phase power distribution. Approximately 12 to 15 amps per phase at 480V continuous draw depending on PSU efficiency conditions.

Jaké chlazení používá?

Liquid to chip hydro cooling. The A4 Ultra Hydro requires external facility hydro infrastructure: coolant distribution unit (CDU), dry cooler or chiller, heat exchanger, pumps, and plumbing connecting miner cold plates to facility cooling loops. Unlike the Bitmain L11 HU6 with integrated all in one cooling, deployment of the A4 Ultra Hydro requires existing hydro capacity or facility CapEx to build it. Hydro cooling enables sustained operation across Bitdeer's 20 to 55 degrees Celsius ambient range without throttling.

50 dB from internal cooling components per MillionMiner specification. Liquid to chip hydro cooling drops noise to approximately 75 percent less perceived loudness than the 75 dB industrial air cooled SHA-256 standard. Staff can work around deployed hardware without hearing protection. Suitable for shared data center environments and multi tenant facilities where air cooled deployment creates tenant acoustic complaints.

Jak se A4 Ultra Hydro porovnává s Bitmain S23 Hydro?

Bitmain S23 Hydro at 580 TH/s, approximately 5,510W, and 9.5 J/TH. Bitdeer A4 Ultra Hydro at 886 TH/s, 8,372.7W, and 9.45 J/TH. The A4 Ultra Hydro delivers approximately 53 percent more hashrate per unit at essentially identical efficiency per terahash. Both miners sit at the efficiency frontier of current generation Bitcoin hydro hardware. Operators choosing between them weigh hashrate density per rack slot (A4 Ultra Hydro favors), Bitmain ecosystem maturity (S23 Hydro favors), and supply availability.

Jaké je rozmezí teplot?

Oficiální specifikace série A4 od Bitdeer pokrývá okolní provozní rozsah teplot od 20 do 55 stupňů Celsia pro hydro modely. Minimální hodnota 20 stupňů odráží potřebu chlazení hydro systémem, aby teplota chladicí kapaliny zůstala nad rosnými body kondenzace. Maximálních 55 stupňů Celsia je vyšší než u běžných ASICů SHA-256, protože hydro chlazení zvládá maximální tepelné zatížení čipu nezávisle na okolním vzduchu. Stránka produktu MillionMiner uvádí rozmezí od 5 do 45 stupňů Celsia, což se zdá být v rozporu s oficiální specifikací Bitdeer; před plánováním nasazení v chladném či horkém klimatu je třeba se s MillionMiner potvrdit.
