Model Z15 from Bitmain mining equihash algorithm using a most hashrate of 840 kH/s for an influence use of 2780W. The Antminer Z15 (420Kh) incorporates a hash fee of 420 KH/S While using the Equihash algorithm. Notice that hashrates are only similar concerning miners that use the same algorithm. https://sethvuhtf.activoblog.com/47961557/how-to-set-up-a-z15-antminer
