Bitdeer unveils new 1 PH/s mining rig

Nasdaq-listed Bitcoin (BTC) mining company Bitdeer has unveiled its new Sealminer A4 Ultra Hydro mining rig on X. The machine features a hashrate of one petahash per second (PH/s) per unit. In high-performance mode, the rig exceeds 1 PH/s with a power efficiency of 10 joules per terahash (J/TH). According to a video released by the company, the number of miners needed to achieve a 1 PH/s hashrate has decreased from 1,000 in 2015, 71 in 2017, and 10 in 2021 to just a single unit today. A petahash per second is a unit of mining speed that represents the scale of hash calculations a miner performs per second.
