Which Bitaxe Should You Buy? Supra vs Gamma Picker

Answer three quick questions and we will point you to the right Bitaxe — the open-source solo Bitcoin miner D-Central hand-builds in Canada. New to it? Start with the Build Your First Bitaxe guide.

Which Bitaxe is right for you? The honest comparison

Short answer: if you do not want to choose, the Bitaxe Starter Build ships ready to run — board, case, matched PSU and heatsink in one hand-built kit. If you would rather pick a board yourself, most first-time buyers are happiest with the Gamma: it is the best balance of hashrate and efficiency from a single chip. Want the lowest cost and the quietest desk? The Supra. Chasing the most hashrate from one device? The dual-chip GT. Running several chips for serious aggregate hashrate? The Hex (or a NerdQaxe+). Every figure below is checked against our own hardware notes, not marketing copy.

Model	Chip	Hashrate	Power	Efficiency	From (CAD)	Best for
Bitaxe Supra	BM1368 (5nm, S21-class)	~0.7 TH/s (625–775 GH/s)	~12 W	~16–18 J/TH	$184.99	Lowest cost, quietest, coolest desk setup
Bitaxe Gamma	BM1370 (5nm, S21 Pro-class)	~1.0–1.2 TH/s	~18–21 W	~15 J/TH (tuned)	$224.99	Most hashrate from one chip + tuning headroom
Bitaxe GT	dual BM1370 (5nm)	~2.15 TH/s	~43 W	~20 J/TH	$269.99	Maximum hashrate in one compact device
Bitaxe Hex	six ASIC chips	Highest aggregate in the family	Higher	Varies by board	$389.99	Serious aggregate hashrate / heat reuse

Prices in CAD, before tax and shipping, as of June 2026 — see each product page for the current price. Hashrate and efficiency are typical stock values; the Gamma reaches ~15 J/TH only when tuned. The dual-chip GT and the six-chip Hex are not single-chip boards — they trade desk space and power for more total hashrate. Prefer to build from parts? See our DIY Kits.

Which Bitaxe? Frequently asked questions

Which Bitaxe should a beginner buy?

If you want the simplest path, the Bitaxe Starter Build is the decision-free option: a Bitaxe plus case, matched PSU and heatsink, assembled and tested before it ships from Laval. If you would rather buy just the board and add your own accessories, the Supra is the lowest-cost, coolest-running single-board Bitaxe to learn on.

What is the difference between the Bitaxe Supra and the Bitaxe Gamma?

The Supra runs the BM1368 (Antminer S21-class, 5nm) at roughly 0.7 TH/s while drawing only about 12 W — cool, quiet and the cheapest way in. The Gamma steps up to the BM1370 (S21 Pro-class, 5nm) for about 1.0–1.2 TH/s and a best-case ~15 J/TH when tuned, at the cost of more power (~18–21 W) and a bit more heat. Full breakdown: Gamma vs Supra.

Which Bitaxe has the highest hashrate?

For the most hashrate from one compact device, the dual-BM1370 Bitaxe GT pushes about 2.15 TH/s. For the most total hashrate in the family, the six-chip Bitaxe Hex goes further still — it just uses more power and space.

Is a Bitaxe profitable?

Treat a single Bitaxe as a solo-mining lottery ticket, not a daily income source. It costs only a few dollars a month in electricity to run, and it gives you a real, if long, shot at the full block reward on your own terms. If steady profit is the goal, a desk-sized solo miner is the wrong tool — the appeal is sovereignty and the lottery, not yield.
