Profitability Comparison
Avalon A1346
Avalon A1566
Based on BTC price of $78,236 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Two generations of Canaan's Avalon miners. The A1346 served the previous era while the A1566 brings current-gen performance.
The A1566 is a meaningful upgrade in both hashrate and efficiency. The A1346 only makes sense at very low purchase prices or for operators already invested in the Avalon ecosystem.
Spec Deltas
Stripped to the numbers, this is how far apart the Avalon A1346 and Avalon A1566 sit on each measurable spec:
- Avalon A1566 68% more hashrate (110 vs 185 TH/s)
- Avalon A1346 4% better power draw (3,300 vs 3,420 W)
- Avalon A1566 38% better efficacité (30.0 vs 18.5 J/TH)
- Avalon A1346 17% better weight (12.3 vs 14.9 kg)
- Avalon A1566 4% more heat output (11,260 vs 11,669 BTU/hr)
Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| Avalon A1346 | Metric | Avalon A1566 |
|---|---|---|
| $2,800 | Upfront cost (MSRP) | $5,500 |
| -$3.96 | Daily net profit | -$1.55 |
| -$4,245 | Net after 1 year | -$6,065 |
| -$5,691 | Net after 2 years | -$6,630 |
| -$7,136 | Net after 3 years | -$7,194 |
| Does not pay back at current rates (negative daily profit) | Payback period | Does not pay back at current rates (negative daily profit) |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
