This product exceeded 1 PH/s in high-performance mode, with a power efficiency of 10 J/TH. According to a video released by the company, the number of miners required to achieve 1 PH/s was 1,000 in 2015, 71 in 2017, and 10 in 2021, but has now been reduced to just one. PH/s is a unit of mining speed representing petahashes per second, indicating the scale of hash computations performed by a miner per second.
