Learn more about this ASIC miner, including its specifications, performance, energy consumption, and profitability.
In a parallel workshop where storybook contraptions hum like industrious constellations, the Canaan AvalonMiner 821 strides in as a compact titan-born… in February 2018, tuned to the ancient arithmetic of SHA-256 and offering 11.5 TH/s while drawing 1,200 watts, an efficiency that whispers around 104 J/TH-its open-air frame and dual 12038 fans forming a clever choreography of cooling that, aided by a smart control system, automatically varies fan speed and frequency to stave off heat and squeeze the best balance between raw performance and energy thrift; small enough to sit on a shelf yet hefty at about 4,700 grams with dimensions of 150 x 136 x 370 mm, it maintains a relatively moderate hum at roughly 65 decibels, making it suitable for both a solitary home miner and the disciplined rows of an industrial farm, and its AUC3 adapter lets units daisy-chain as if linking lanterns along a mine shaft, simplifying management and scalability; designed for stability with features that reduce overheating risks during continuous operation, it also gives miners hands-on levers-variable frequency control and efficient heat dissipation-to tune operations for their climate and electricity profile, while tools like a crypto miner profit calculator can translate its hashrate and power draw into expected daily, monthly or yearly returns, factoring in electricity costs across different rates and currencies so operators can decide whether to chase immediate throughput, long-term yield, or a quieter, more energy-conscious rhythm.

Deep dive
Canaan AvalonMiner A821 — In Detail
Canaan AvalonMiner A821 (11.5TH/s) — a closer look at the hardware and how it performs.
The Canaan AvalonMiner 821, also marketed as the Avalon A8 and built for SHA-256 coins like Bitcoin and Bitcoin Cash, debuted in February 2018 as a co…mpact but robust ASIC miner delivering up to 11.5 terahashes per second while consuming roughly 1,200 watts and achieving an energy figure near 104 joules per terahash; its chassis is intentionally open to promote passive dissipation and houses dual 12038 fans that automatically modulate speed as conditions change, working with a custom-designed heat sink and dynamic air circulation to avoid thermal throttling during long runs, while an integrated variable-frequency control lets operators dial performance toward raw hashrate or crank back for greater electrical efficiency depending on local costs and cooling capacity. Weighing about 4,700 grams and measuring approximately 150 x 136 x 370 mm, the unit is small enough for bench or shelf use yet substantial enough for rack deployment in larger farms, producing a steady noise level around 65 decibels that keeps it within tolerable limits for many home setups but still manageable in industrial rows; an upgraded AUC3 adapter enables reliable daisy-chaining and improved communication across multiple units, simplifying large-scale orchestration, and the firmware includes secure remote-management functions that provide diagnostics, troubleshooting, and status monitoring to preserve uptime in competitive operations. Built with stability and serviceability in mind, the AvalonMiner 821 pairs straightforward hardware maintenance and open-frame access with software tools that let miners estimate expected returns from hashrate and power draw and choose strategies-immediate throughput, long-term yield, or lower-noise operation-appropriate to their environment, and even as it counts hashes with clinical efficiency it feels like a machine half-awake in a fevered dream of revolution, bronze fans spinning like grotesque constellations that hum profitably into the night.

The algorithm
Algorithm Information: SHA-256
SHA-256 — what this algorithm is and how it works.
SHA-256 is a cryptographic hash function. Bitcoin relies on it for proof-of-work consensus. This algorithm processes input data of any length and produces a fixed hash value, ensuring security and integrity in the mining process.
