How the models differ

All our miners run the open AxeOS firmware and are based on the efficient BM1370 ASIC – they differ mainly in the number of chips and therefore in hashrate, power draw and price.

  • Bitaxe Gamma 601 – the affordable, economical entry into solo mining (~1.3 TH/s, ~15 W).
  • NerdQaxe ++ – the balanced middle ground with much more hashrate (~4.8 TH/s) at moderate power.
  • NerdOctaxe – maximum hashrate per device (up to 12 TH/s) and the best chance at solo mining.

Hashrate, power draw & efficiency explained

Hashrate (TH/s) is how many computations the miner performs – more hashrate means a higher chance of finding a block. Power draw (watts) drives your electricity bill, and efficiency (J/TH) tells you how much energy is needed per terahash. Because all models share the same BM1370 ASIC, their efficiency is nearly identical – so the real trade-off is simply hashrate versus power draw and price.

Do not forget cooling

Cooler ASICs run more stably, last longer and leave headroom for tuning. For a Bitaxe or Nerdaxe Gamma, a cooling upgrade or the AXP60 Copperzilla copper cooler helps a lot; for the NerdQaxe there is a Performance Case for better airflow. Details in AxeOS tuning.

Keep an eye on running costs

Before running a miner 24/7, do the math: see calculate electricity costs and, for an honest view of returns, mining profitability.

Frequently asked questions

Which Bitaxe or NerdQaxe should I buy?
For an affordable start, choose the Bitaxe Gamma 601 (~1.3 TH/s). Want clearly more hashrate while staying living-room friendly? The NerdQaxe ++ (~4.8 TH/s). For the best solo-mining odds per device, the NerdOctaxe (up to 12 TH/s).
Do more ASICs mean better efficiency?
No. All models use the same BM1370 ASIC at a similar efficiency (~16 J/TH). More chips give you more hashrate at proportionally higher power draw – not a lower cost per terahash.
How much electricity does each miner use?
Roughly: Bitaxe/Nerdaxe Gamma ~15 W (≈ 3–4 €/month), NerdQaxe ++ ~80 W (≈ 17 €/month), NerdOctaxe ~200 W (≈ 44 €/month) at 30 ct/kWh in 24/7 operation.
Which miner is quietest for the living room?
A single Bitaxe or Nerdaxe Gamma is whisper-quiet. The NerdQaxe ++ stays living-room friendly with light cooling; the NerdOctaxe is audible and better suited to a study or hobby room.
Can I expand later?
Yes. Thanks to open AxeOS firmware and identical pool setup, you can start small and add more devices anytime.
