The Antminer S19 Pro is the most profitable ASIC miner for Bitcoin and the SHA-256 algorithm for now. It is manufactured by Bitmain, a leading mining hardware manufacturing company, which makes it a top choice among Bitcoin mining firms and individuals.
You do not expect many devices to beat this equipment’s efficiency offer of 29.7 J/TH. The device is built using the next-gen 5nm chip, a second-generation chip dedicated to SHA-256 mining.
Compared to other devices in this list, it certainly is the most economical and efficient mining device in the market currently. It also beats the other S19 Series product, the S19 although it is heavier.
Weight: 15,500 g
Noise Level: 75db
Temperature: 5 – 45 °C
Maximum Hash rate: 110 Th
Power consumption: 3250 W (±5%)

This device manages a power efficiency of 31J/TH (joules per Tera hash), hence one of the few top Bitcoin ASIC miners that can reach that efficiency rating. It measures about 16.875” length by 5.75” width by 8.8125” height. Testing reveals that the power efficiency, power consumption, and hash rates do not fluctuate by huge margins when the device is in use. The algorithm is SHA-256 – Bitcoin mining and over 10 other cryptos.
The device is more efficient than the Whatsminer M30S+. It is manufactured by the Shenzhen-based MicroBT and is also sold with a 6 months warranty, 135 days payback period, and features plastic material. It connects to the computer through LAN.
Weight: 10,500 g
Noise Level: 75db
Temperature: -5 – 35 °C
Maximum Hash rate: 112TH/s±5%
Power consumption: 3472 watts+/- 10%

The ASIC mining device is manufactured by Canaan, a renowned Bitcoin mining hardware company that has high power consumption. You can mine Bitcoin and other SHA-256 algorithm coins with this miner, at a power efficiency of 38J/TH.
The Avalonminer 1246 is made with an integrated design that ensures reliability. The power supply is 285V, 16A, 50Hz to 60Hz AC. With a dimension of 331 mm X 195 mm X 292mm, it does not have a problem fitting, even in a cabinet.
Weight: 12,800 g
Noise Level: 75db
Temperature: -5 – 35 °C
Maximum Hash rate: 90Th/s
Power consumption: 3420W

Although this device has registered low profitability, it can effectively mine SHA-256 algorithms at an efficiency of 0.054j/Gh. We can therefore apply it in the ASIC mining of Bitcoin, Bitcoin Cash, Bitcoin BSV, Peercoin, eMark, Unbreakable, Joulecoin, Curecoin, and Acoin. It measures 230 x 350 x 490mm.
It features two fans to assist in cooling, although the noise level does not favor application in residential areas.
Weight: 10,500 g
Noise Level: 75db
Temperature: -5 – 35 °C
Maximum Hash rate: 68TH/s +/- 5
Power consumption: 3312 watts +/- 10%

AvalonMiner 1166 Pro is used to mine Bitcoin, Bitcoin Cash, Bitcoin SV, and other SHA-256 cryptocurrencies. Released in August 2020, it manages a considerably high hash rate and power consumption compared to most of the devices on this list.
It is a popular Bitcoin ASIC mining device given that it is manufactured by Canaan, which is a leader in mining hardware and one of China’s National high-tech enterprises.
The device is 16 nm in size and manages an efficiency of 0.042 j/Gh, which means it is still a profitable Bitcoin ASIC mining hardware to date. It also features four fans used for cooling purposes. Depending on the electricity costs at your location, expect this device to give off $2.77 per day, and $83.10 per month, and $1,011.05 per year.
