Power cost per month: the highest power figure of the device, 730 hours of continuous operation, 30 cents per kWh. For your own rate use the mining calculator; the formula is explained in calculating mining power costs.

What the columns mean

Hashrate in TH/s is how many attempts a device makes per second, watts set the power bill, and J/TH relates the two. What separates the devices is mainly the number of chips and their generation. One BM1370 sits in the Bitaxe Gamma 601 and the Nerdaxe Gamma, four in the NerdQaxe ++, six in the Bitaxe Gamma Hex 1300, eight in the NerdOctaxe and in the NerdOctaxe Hydro. The Nerdaxe Gaia models use the newer BM1373 and reach around 10 to 11 J/TH, the Bitaxe Supra Hex 702 with six older BM1368 around 21. The Avalon Nano 3S hashes with Canaan chips (around 21 to 23 J/TH). How the two multi-chip Nerd models compare in detail is covered in NerdQaxe ++ vs. NerdOctaxe.

Power and heat

The monthly column assumes 30 cents per kWh; enter your own price in the mining calculator. What works with solar power and how much heat the devices give off is answered in the questions below.

Firmware: AxeOS, NerdOS and one exception

Bitaxe devices run AxeOS; Nerdaxe, NerdQaxe and NerdOctaxe run NerdOS, an open offshoot of AxeOS. In both you set pool, frequency and voltage yourself, in the browser and without a manufacturer account. The exception is the Avalon Nano 3S with the closed firmware from Canaan. You install AxeOS and NerdOS updates via the dashboard or with our web flasher.

Tuning and cooling

Raising frequency and voltage calls for cooling headroom. For the NerdQaxe ++ and NerdOctaxe there is the larger AXP90 Copper Pro, and the Performance Case gives the NerdQaxe more airflow. The AXP60 Copper Pro copper cooler fits the Bitaxe Gamma and Nerdaxe Gaia but not the Nerdaxe Gamma; for the Bitaxe and Nerdaxe Gamma there is the ICE Tower Low Profile Kit. The settings afterwards are explained in AxeOS tuning.

Buy or rent

A Bitaxe Gamma 601 or a Nerdaxe Gamma is a good first device; every device is listed under buy a Bitcoin miner. If you lack the space or cheap power, a Virtual Miner delivers rented hashrate on pool.opensourceminers.de for your address.

Frequently asked questions

How much heat does a miner give off?
Almost all of the power it draws. A Bitaxe Gamma at 15 to 18 watts barely warms anything, a NerdOctaxe at around 200 watts noticeably helps heat a small room. The NerdOctaxe Hydro releases around 220 watts into the room through its radiators; our guide on heating with the Hydro shows what that does in winter.
Which devices suit solar power?
Small ones, because they run at full speed on little surplus: the Bitaxe Gamma, Nerdaxe Gamma and Nerdaxe Gaia need less than 30 watts, a NerdQaxe ++ around 80. Our guide on Home Assistant explains how to tie a miner to your surplus.
Which device fits which room?
Single-chip devices sit on a desk without bothering anyone. From four chips upwards you hear the fan: the NerdQaxe ++ still works in living space with good ventilation, the spec sheet of the Avalon Nano 3S gives 29 to 36 dB, and the NerdOctaxe belongs in a study or hobby room.
What does a miner cost per month in electricity?
Watts times 730 hours times your electricity price. At 30 cents per kWh that is just under €4 for a Bitaxe Gamma 601 at up to 18 watts, about €17.50 for a NerdQaxe ++ at 80 watts and just under €44 for a NerdOctaxe at 200 watts. The power column does this for every device, and the mining calculator takes your own rate.
How much hashrate do I get per watt?
The efficiency column shows it in J/TH: the lower the figure, the more hashrate per watt. The most economical device in our range is the Nerdaxe Gaia with the newer BM1373 (around 10 J/TH). Devices with four or eight BM1370 need somewhat more energy per terahash than the single-chip models (around 17 against 12 to 13 J/TH), but deliver far more hashrate.
Buy a device or rent hashrate?
A device is yours but needs power and space. A rental runs for a fixed term on pool.opensourceminers.de for your Bitcoin address, with no power or noise at your place; the smallest matches a Bitaxe Gamma at 1.3 TH/s. Cheap power of your own speaks for the device, no space or expensive power for the rental.
