Model Z15 from Bitmain mining equihash algorithm by using a optimum hashrate of 840 kH/s for an influence consumption of 2780W. The Antminer Z15 (420Kh) contains a hash rate of 420 KH/S Using the Equihash algorithm. Notice that hashrates are only similar amongst miners that use the identical algorithm. https://antminerz15secondhand98641.getblogs.net/71769825/antminer-z15-specifications-explained
