ASIC miner manufacturers
Who builds the miners and how the brands differ
Breakdowns of mining hardware makers: history, chips, series, cooling, firmware, spare parts, repair and an honest comparison between them.
The section grows brand by brand. Every breakdown follows the same outline: company profile, year by year history, product lines, a full model catalog linked to the profitability calculator, supported algorithms and coins, technologies, cooling types, firmware, spare parts, repair, efficiency by series and a comparison with rivals.
Figures come from our catalog and from official specifications, and anything disputed is marked as disputed.
If you are starting from scratch, read the general guide first: how ASIC miners work, how to choose one, connect it and keep it running.
