Cryptocurrency prices have been in freefall with Ethereum shedding nearly 40% over the past month, falling to under $2,500 for the first time since late July 2021. Falling crypto prices mean lower profits for miners, and therefore more GPUs for gamers. As expected, graphics card mining feasibility has been consistently depleting over the past couple of months. It now takes 30 months to break even if you buy a GeForce RTX 30 series graphics card for mining, and given the uncertainty over crypto prices, and the looming Ethereum 2.0 merger, there’s a good chance that miners buying new hardware at this point will never be able to recoup their investments.
Stats provided by well-known Russian miner “ProTON” show that even with a GeForce RTX 3080 Ti or a 3090, you’ll need close to three years (36-37 months) to recoup your initial hardware investments. Unexpectedly, the GeForce GTX 1660 Super and the 1660 Ti have the shortest turnover period of 28 months, followed by the RTX 3060 with 30 months.
The worst graphics card for cryptomining, however, is the AMD Radeon RX 6900 XT. Requiring more than 3 years or 38 months to break even, the top-end RDNA 2 GPU is a miner’s nightmare. The combination of a massive L3 cache and a slim bus width makes for a starved compute digestor. This also partly explains why the Radeon RX 6900 XT is one of the most widely available graphics cards despite costing well over a thousand dollars.
