Bitcoin mining hardware maker Bitmain still has a “minuscule lead” over competitor Microbt despite the former’s ongoing power struggle and supply chain issues, according to Bitmex.
Researchers at the derivatives exchange tested flagship products from the two companies, Bitmain’s Antminer S19 Pro and Microbt’s Whatsminer M30S+.
Over a three-day period, the team measured various performance metrics such as energy efficiency, hashrate, temperature, sound, and “even the airflow speed from the main outlet.”
It concluded that the Antminer machine, though priced higher, is more energy-efficient, achieving 29.7 joules per terahash (J/TH), compared with the Whatsminer’s 34.4 J/TH.
Microbt has released a new Whatsminer M30S++ with reported efficiency of 31.0 J/TH, but even that is “still inferior to Bitmain,” said Bitmex, in a report published August 17.
