The lineup includes air-cooled, hydro-cooled, and immersion models, designed to reduce energy costs and increase fleet uptime for large-scale operators.
California-based company Auradine has announced the launch of its new generation of bitcoin mining machines, Teraflux, boasting energy efficiency levels reaching 9.8 J/TH.
Founded in 2022, Auradine stands out as the only U.S.-based company that designs and manufactures ASICs entirely within American territory. This feature is particularly relevant in the current geopolitical context, where tariff pressures from the Trump administration have heightened the focus on technological independence from Asian suppliers.
The ASIC market has long been dominated by Bitmain Technologies, the Chinese giant that controls over 80% of global market share with its Antminer line.
Three ASIC configurations
The new Teraflux family comes in three cooling variants, each optimized for specific operational environments:
- immersion models: these are the flagship units, delivering efficiency as low as 10.7 J/TH in standard mode and 9.8 J/TH in eco mode, with computing power reaching up to 360 TH/s;
- hydro-cooled systems: offering the best balance between efficiency and performance, they operate at 11 J/TH in standard mode and 9.8 J/TH in eco mode, with hash capacity up to 900 TH/s;
- air-cooled units: designed for traditional installations, these ASICs achieve 11 J/TH in standard mode and 10.3 J/TH in eco mode, with a maximum hashrate of 310 TH/s.
According to data from Hashrate Index, the new Teraflux models are competitively positioned against industry-leading devices. Bitmain’s Antminer S21 Hydro U3 and S23 Hydro typically operate around 9.5 J/TH, while the Antminer S23 and S23 Immersion are closer to 11 J/TH.
In terms of absolute computational power, the Teraflux lineup falls slightly below the top-tier models: the hydro-cooled version reaches 900 TH/s compared to the Antminer S21 Hydro U3’s 1,160 TH/s, but surpasses units like the Sealminer A3 Pro Hydro (660 TH/s) and the Antminer S23 Hydro (580 TH/s).
FluxVision: the management software
Alongside its hardware launch, Auradine has upgraded FluxVision, its centralized fleet management platform for ASICs. The system allows operators to control energy consumption, configurations, updates, and load reduction strategies.
A new mobile app, set to launch on the App Store and Google Play by the end of the month, will enable real-time monitoring and remote management of mining operations from portable devices. The cloud-based dashboard integrates advanced tools for distributed management of hashrate and power, automated scheduling, and pool configuration.
Investment and market outlook
Auradine closed a $153 million Series C round last April, led by StepStone Group with participation from Maverick Silicon, Premji Invest, Samsung Catalyst Fund, Qualcomm Ventures, Mayfield, MARA Holdings, and GSBackers. The company’s total funding now exceeds $300 million.
Rajiv Khemani, Auradine’s co-founder and CEO, stated:
“Our third-generation Teraflux Bitcoin miners deliver a significant leap in performance and efficiency. For too long, miners have had to choose between performance and reliability. We have now finally closed that gap, delivering top efficiency, seamless fleet control, and real customer support in one trusted platform.”
Last March, the company had unveiled the first hydro-cooled ASIC ever designed in the United States. Today, its machines power more than 40 major operators, including Marathon Digital Holdings.
The first samples of the new Teraflux generation are expected in Q2 2026, with volume shipments beginning in Q3 2026.
