It seems that another real ‘cryptocurrency mining bubble’ is emerging. The news that there is a shortage of certain semi-finished products will not help, but it is now clear that a good part of the cards are going to miners of certain cryptocurrencies. Even the brand new RTX 3000 laptops are already being used because it is financially interesting enough.
Tom’s Hardware has figured out how profitable mining Ethereum is on a large number of video cards. We are not trying to convince hardware enthusiasts to jump on the mining wagon, it is especially interesting to see which hardware is the most efficient. For example, this could also be an indication of which video cards will be available again first – after all, graphics cards that are no longer profitable in the course of the year will no longer be bought up.
With the difficulty level As of the time of writing, you can mine 0.006538 ETH at 100 MH / s per day. You will have to deduct the costs of your hardware (not just the video card), the same applies to any electricity costs. Tom’s Hardware used either NBminer or PhoenixMiner, depending on which video card was tested. It should be emphasized that the efficiency increases with an increasing number of video cards: less energy is then consumed by the CPU, the working memory, an SSD and other parts that every miner needs. That is also a major reason why many miners put large amounts of cards in a single setup.
The GeForce RTX 3090 has by far the highest hashrate with 106.5 MH / s. However, the high purchase price is a downside, and there also appear to be cards that can accomplish the task more efficiently. Tom’s Hardware has allowed him to consume 279 watts with this hashrate.
The RTX 3080 is the next highest hashrate card in the list. With a consumption of 234 watts, it achieves a hashrate of 93.9 MH / s. This makes it slightly more efficient than the RTX 3090. The most efficient card is the RTX 3070, which can achieve a maximum of 61.3 MH / s at 123 watts.
Also interesting is that both the RX 5700 and the 5700 XT are still relatively attractive. They reach 51.3 MH / s and 51.8 MH / s, while consumption is 119 and 133 watts respectively. This makes them even more efficient than the RTX 3090. The actual performance will of course vary from card to card, and the settings can also have a major influence. All in all, these two Navi 10 products appear to be the most cost effective to mine, not only because of the efficiency perspective but also because they are relatively inexpensive.
The RX 590 and GTX 1060 have also been tested. It is good that the efficiency of mining hardware has increased considerably in recent years. You’ll be able to make a profit with it, but miners are more likely to get the newer cards than Polaris and Pascal video cards.
