Antminer S9 vs Bitaxe Supra
Side-by-side specs, profitability, and home mining comparison.
Quick verdict
For most buyers the Antminer S9 is the stronger pick — Roughly 10,000x more hashrate — there is no contest on raw mining power. The Antminer S9 runs 14.0 TH/s at 96.4 J/TH; the Bitaxe Supra runs 700.0 GH/s at 17.1 J/TH.

Profitability Comparison
Antminer S9
Bitaxe Supra
Based on BTC price of $64,947 and current network difficulty as of Jun 17, 2026. Actual results vary.
Verdict
The legendary Antminer S9 versus the modern Bitaxe Supra. Old-school industrial ASIC power versus new-wave open-source solo mining — could not be more different.
The S9 produces vastly more hashrate but is loud, power-hungry, and requires 240V. The Bitaxe Supra is silent, runs on USB power, and embodies the decentralized solo mining ethos. Choose the S9 for raw hashrate or the Supra for the home solo mining experience.
Spec Deltas
Here is every spec where the Antminer S9 and Bitaxe Supra actually differ, with the gap quantified:
- Antminer S9 1900% more hashrate (14.0 vs 0.7 TH/s)
- Bitaxe Supra 99% better power draw (1,350.0 vs 12.0 W)
- Bitaxe Supra 82% better efficacité (96.4 vs 17.1 J/TH)
- Bitaxe Supra 54% better noise (76.0 vs 35.0 dB)
- Bitaxe Supra 93% better weight (4.2 vs 0.3 kg)
- Antminer S9 11162% more heat output (4,606.2 vs 40.9 BTU/hr)
- Bitaxe Supra 355% more score de minage domestique (22.0 vs 100.0)
Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| Antminer S9 | Metric | Bitaxe Supra |
|---|---|---|
| — | Upfront cost (MSRP) | $89 |
| -$2.78 | Daily net profit | -$0.01 |
| -$1,016 | Net after 1 year | -$91 |
| -$2,031 | Net after 2 years | -$93 |
| -$3,047 | Net after 3 years | -$95 |
| — | 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.

Foire aux questions
Can a Bitaxe Supra compete with an S9 on hashrate?
No. The S9 produces roughly 13.5 TH/s versus the Supra's ~0.6 TH/s. They serve completely different purposes — the S9 is a mining machine, the Supra is a solo mining lottery ticket and decentralization tool.
Which is better for home use?
The Bitaxe Supra, by far. It is silent, draws under 15W, and sits on your desk. The S9 is a 75+ dB industrial machine that requires dedicated infrastructure.
Is there any advantage to the Bitaxe over the S9?
The Bitaxe is silent, portable, open-source, and uses minimal power. It decentralizes Bitcoin mining by enabling anyone to participate without industrial equipment.
