Bitcoin Miners

This is not an endorsement of any listed company. These figures are based on estimates made by the company involved. A good deal of research on your chosen company should be done, with the realization that even then there is no sure thing.



The percentages above the miner columns represent a constant rise in difficulty. Below this is the percent of bitcoin gained, minus initial cost. This assumes mining 24 hours per day for a year. Tax and shipping not included. Remember, depending on how far the manufacturer has to ship could change your ROI dramatically.

Bitcoin Mining Legacy Tables


This table is organized by GH/BTC. This is posted for people used to the legacy table. The profitability shown on the main page is a better representation of the true data, especially when used in conjunction with the individual pages for mining equipment manufacturers.


On ASICsAt the moment there is some worry about ASICs being so naturally centralized. When hashing was done on a CPU anyone who had a computer could be involved with mining. After GPU’s became the portal through which bitcoin entered the world and the price of bitcoin started rising centralization began to creep in. Still, though, anyone can go to the store, or order a graphics card online.

FPGA’s are rare in comparison. Graphics cards are common in every modern computer. The FPGA is primarily used by the technology and development community. Though not much less expensive than a GPU per megahash, the FPGA uses much less electricity and stays cooler. This becomes more important as energy costs cut deeper into the diminishing returns.

Though not usually used by consumers, FPGAs are quite valuable for an ever growing number of applications. This makes them resalable, and available. Quite the opposite of what we get with ASICs. ASIC stands for Application Specific Integrated Circuit. When an ASIC is needed it must be designed for that job, and that job only.

At some point the difficulty will go so high that even the most powerful miners being designed will give a negligible return. Though it is not unthinkable that there could be a use for a bunch of old SHA-256 ASICs, nobody has come up with anything better than ‘doorstop’ yet.

The last and largest problem with ASICs coming to bitcoin is that they are made specifically for a task. This means that they don’t naturally exist in the wild like all the former hashing equipment. You can imagine that the process of creating a new ASIC chip takes a great deal of capitol and know how.
