Avalon Mini 3 vs Avalon Q
Avalon Mini 3 is an entry-level Bitcoin miner that delivers 37.5 TH/s at low power consumption (about 800 W), making it a convenient choice for home miners or small-scale operations where efficiency, noise, and low upfront cost matter. Its modest size and power draw make setup simple and flexible.
Avalon Q significantly boosts output — with 90 TH/s and stronger energy efficiency (~18.6 J/TH), it suits miners who want more hashing power without jumping to industrial-scale rigs. While it demands more electricity and produces greater heat, its higher throughput makes it better for miners seeking faster returns or larger-scale mining from a compact machine.
If you’re starting out or value low power usage and simplicity, go with Avalon Mini 3. If you need more hash output and are ready to manage higher power/heat, Avalon Q is a better fit.
| Field | Avalon Mini 3 | Avalon Q |
|---|---|---|
| Hashrate | 37.5 TH/s (Avalon Miner – Canaan Official Shop) | 90 TH/s (Avalon Miner – Canaan Official Shop) |
| Power Consumption | ~ 800 W (Avalon Miner – Canaan Official Shop) | ~ 1674 W (Avalon Miner – Canaan Official Shop) |
| Energy Efficiency | ~ 21.3 J/TH (BT-MINERS) | ~ 18.6 J/TH (Mining Now) |
| Cooling / Setup | Air-cooled, standard home-power voltage (110–240V) (Avalon Miner – Canaan Official Shop) | Air-cooled, standard home-power voltage (110–240V) (BT-MINERS) |
| Noise & Size / Suitability | Compact and more modest — easier for home or small-scale mining; lower heat & noise | Higher output — needs more power, more ventilation, better for serious small-to-medium miners |
| Best For / Use Case | Entry-level miners, home rigs, small-scale mining, budget-conscious users | Users needing more hashing power while still keeping manageable infrastructure — small to mid-size farms or serious home miners |
| Pros | Low power consumption, compact size, easy setup, lower upfront cost | Higher hashrate, better efficiency per TH, significantly more mining output per unit |
| Cons / Trade-offs | Lower total output — may take longer to earn; less hash per second | Higher power consumption and heat output; requires better ventilation and may have higher noise |
