Which miner is right for you?
Choose by what matters most to you:
You want
Get started affordably
Economical and quiet – the ideal first miner.
Bitaxe Gamma | 1.3 TH/s €139.00 Buy →You want
Read stats on the device
Large 1.9" display for hashrate & temperature.
Nerdaxe Gamma | 1.3 TH/s €159.00 Buy →You want
More hashrate at home
About 4× the power, still living-room friendly.
NerdQaxe ++ | 4.8 TH/s €349.00 Buy →You want
Best solo-mining odds
Up to 12 TH/s – maximum performance per device.
NerdOctaxe | 12 TH/s €699.00 Buy →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).
- Nerdaxe Gamma – like the Bitaxe Gamma, but with a large 1.9" display for hashrate & temperature.
- 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.
