Nerdaxe Gaia | 2,6 TH/s

The Nerdaxe Gaia is the generation change in the Nerdaxe format. The board carries a single BM1373 ASIC with around 2.6 TH/s at roughly 25 W, so about 10 J/TH – around a third less energy per terahash than the BM1370 generation at roughly 15 J/TH. Everything around it stays familiar: ESP32-S3, AxeOS, 2.4 GHz Wi-Fi, USB-C and the 1.9-inch TFT showing the operating values. The Gaia is a pre-order; the first batch ships from 15 September.

Two things shape everyday use. A 40 mm PWM fan keeps the ASIC in check, and you define its curve in AxeOS. And power draw stays manageable: roughly 25 W add up to about 18 kWh a month – twice the hash rate of a Nerdaxe Gamma for barely more power.

That is exactly the point of solo mining: every hash is a ticket in the same draw the large farms take part in. If your Gaia finds the matching block, the full reward of currently 3.125 BTC plus transaction fees lands on your own address, undivided and with no provider in between. Along the way, your device checks transactions and strengthens the network. How small the chance is, is explained in our solo mining guide.

• Twice the hash rate in the same format: around 2.6 instead of 1.3 TH/s, without a second chip, without a larger power setup and without a rack in the basement.
• Roughly 10 J/TH: power draw only rises from about 15 to 25 W while compute doubles.
• One chip instead of many: fewer components, fewer points of failure and a device that can run around the clock.
• Just as open: AxeOS with your own pool, your own address and free choice of frequency and voltage. No account, no cloud service, no vendor lock-in.

There are two ways to more hash rate: more chips or a better chip. The Gaia takes the second route. That keeps the device small and lets a single 40 mm fan do the job. The price of that design is the ceiling: around 2.6 TH/s is the end of the line, and anyone who wants more changes device class.

For home mining that is the better arithmetic: one device, one power supply, one socket and one number on the display.

The Gaia is a new generation and sold as a pre-order: the first batch ships from 15 September. You secure a unit from it but have to wait. If you want to start right away, the Nerdaxe Gamma is the alternative in the identical form factor: same display, same operation, half the hash rate.

The new ASIC changes nothing about the procedure: a socket, 2.4 GHz Wi-Fi and a browser are enough. The steps in detail are in the Nerdaxe setup guide.

For everyone already running an open-source miner who wants more hash rate without changing device class. The Gaia stays a desktop device with one chip, one fan and one power supply. It also works as a second unit next to a Bitaxe, because firmware and operation are identical.

It is less of a fit in two cases. First, if you want to mine immediately – delivery starts on 15 September. Second, if you are after maximum hash rate: the NerdQaxe++ reaches around 4.8 TH/s but draws roughly 80 W, about three times as much.

Power supply, mount and quick start guide are included; beyond that you only need a socket, your 2.4 GHz Wi-Fi and a Bitcoin address. No PC required, because AxeOS runs on the device.

For the location the same rules apply as for any air-cooled miner: stand it free, do not blow the exhaust against a wall, and keep an eye on the temperature during the first few days. 25 W of waste heat is little, but it still has to go somewhere.

A Gaia on its own is a complete setup. It gets interesting when you make it quieter or put it behind your own infrastructure.

• Cooling for quieter fans and more surface area if you want to raise the clock.
• LiquidBox V5 if your own Bitcoin node should stand next to the miner.
• Power supplies, mounts and small parts for continuous operation.

2.6 TH/s, roughly 25 W, about 10 J/TH and a single BM1373: the Gaia is the upgrade for everyone who wants to stay in the open format and still put more hash rate on the desk. Pre-ordering means being part of the first batch.
