MicroBT has introduced the Whatsminer M79S, a hydro-cooled Bitcoin mining machine with a hashrate of 1.35 petahashes per second (PH/s). This launch positions MicroBT among the elite petahash club, directly competing with industry leader Bitmain. The M79S was revealed at the Bitcoin MENA 2025 event in Abu Dhabi, showcasing superior hashrate capabilities compared to Bitmain's S23 Hydro 3U, although it falls short in efficiency. The M79S is slated for industrial deployment in 2026, coinciding with Bitcoin's network hashrate approaching 1 zettahash per second (ZH/s). This development underscores the rapid advancements in crypto mining technology as companies strive to enhance performance and efficiency in the sector.
