Bitmain, MicroBT, Canaan, Bitdeer – how the manufacturers differ

The chips of all four manufacturers compute the same algorithm. The differences lie in the product range and in what is built around the chip.

Bitmain (Antminer)

• Range: the widest. Air, hydro and immersion in several generations, plus units for other algorithms: the L series for Scrypt, the Z series for Equihash, the D series for X11.
• Hydro: Bitmain states the permitted inlet temperature, up to 40 or 50 °C depending on the model.
• Diagnosis: faults appear as text messages in the kernel log.
• Ecosystem: Antminers are the most widespread. The supply of spare parts, repair guides and firmware alternatives is correspondingly large.

MicroBT (Whatsminer)

• Range: SHA-256 in air, hydro and immersion. Each model is sold in many hashrate bins.
• Hydro: MicroBT states the outlet temperature, up to 70 °C for the M63S+ and up to 80 °C for the M64. For heating systems with a high flow temperature this is an advantage.
• Diagnosis: numbered error codes that you can look up directly.
• Control: three power modes from the factory (Low, Normal, High) and a power limit in watts.

Canaan (Avalon)

• Range: alongside units for commercial operation, a separate line for the home, Avalon Mini 3 and Avalon Q. They run on a household socket and are designed for low noise.
• Hydro: the A1566HA series.

Bitdeer (Sealminer)

• Range: the youngest supplier, with the A2 and A3 series in air and hydro; the A4 series has been announced.
• Hashrate per unit: for the hydro units of the A3 series, Bitdeer states 500 and 660 TH/s, with a deviation of up to ±10%. In our shop they are listed with 550 and 666 TH/s. That is the class of the newest Antminers.
• Ecosystem: the series is young. There are fewer field reports from continuous operation than for Antminers and Whatsminers.

What is the same for all

The warranty is given by the manufacturer, and you submit the claim to them. Duration and conditions differ and are stated in the offer.

How to choose

1. Efficiency and price per terahash first. The manufacturer's name does not change the calculation.
2. Hydro with heat reuse: check which temperature your heat consumer needs and compare it with the manufacturer's figure.
3. Existing fleet: if you already run units from one manufacturer, staying with that manufacturer saves you spare parts, tools and training.
4. Repairing it yourself: the more widespread a unit is, the easier it is to find parts and guides.
