Bitmain Retains Only a ‘Minuscule Lead’ Over Competitor Microbt Amid Ongoing Power Tussle, Says Report

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.

The derivatives exchange Bitmex’s Research department published a side-by-side comparison of the Antminer S19 Pro vs the Whatsminer M30S+. Both of which perform at an average of over 100 TH/s depending on the machine.

In terms of hashrate, a measure of computational power for extracting bitcoin, Whatsminer achieved an average 103.8 terahash per second (TH/s) and Antminer 110.7 TH/s. The figures are 3.8% and 0.6% above the reported levels for both machines, respectively.

Bitmain’s miner was also found to be 10.5°C cooler compared with Microbt’s, largely because of Antminer’s “lower power consumption or superior cooling”. Antminer is even stronger in start-up time, Bitmex said.

Based on an average of five attempts, the Antminer reached its target hashrate in around four minutes, while the Whatsminer took an average of about 27 minutes to boot up.

“Our data…shows that the Bitmain miner has slightly stronger performance than the Whatsminer. However, the Whatsminer appears to have superior stability,” said the exchange.

“In evaluating the relative strength of the companies and their order…
