Popular crypto miner and YouTuber ProTON recently shared a detailed mining profitability breakdown for a wide range of graphics hardware. ProTON’s video comes as cryptocurrencies like Bitcoin touch record high values, but also at a time when GPU supplies are critically short, due to scaling issues on both the 8nm and 7nm processes.
According to ProTON, all Ampere cards are a solid investment towards Ethereum mining, if you’re able to get hold of them at or near retail cost. Even at higher electricity tariffs, the GeForce RTX 3060 Ti, for instance, will effectively pay for itself in 5 months, after which it’ll generate approximately $5 a day.
The GeForce RTX 3070 will take longer to break even but will generate more income per day if left to mine. Interestingly, the value drops significantly once you start looking at lower-end Turing cards. Budget parts like the GeForce GTX 1660 Super will take just as much time to recoup your expenditure as Ampere. However, you’ll only be able to mine $2.5 per day, assuming an exchange rate of 1 ETH per $1000.
This is both good and bad news. For miners, at least, Ampere offers a great way to make significant returns thanks to its power efficiency. For gamers, though, any surge in mining demand could put the precarious GeForce RTX 3000 series supply situation in an even worse position, making cards like the GeForce RTX 3080 a theoretical buy at best.
