How much does graphics card mining ETH earn? American netizens tell you
As the price of Bitcoin continues to break new highs, the price of mainstream ASIC mining machines is also rising. Taking the Antminer S19 95T as an example, the futures price on the official website shows 19,200 yuan, but the lowest off-site transaction price has reached 25,000 yuan. For Bitcoin mining, which has been monopolized by large institutions and giants, Ethereum mining, the second largest cryptocurrency by market value in the world, is much more friendly.
Recently, Simon Byrne, a netizen who lives in Las Vegas, USA, directly assembled an Ethereum graphics card mining machine with multiple GeForce RTX 3080s. According to the current price/expected price and cost ratio of Ethereum, his family-level Ethereum graphics card Mining profits are not bad!
According to foreign media TweakTown, the Ethereum mining machine made by Simon Byrne consists of 78 NVIDIA GeForce RTX 3080 graphics cards. There are 13 rows of 6 cards in each row, each graphics card consumes about 300W of power, and Byrne's self-made mining machine consumes about 23.4KW of electricity. Of course, this does not include other power consumption (such as cooling and air conditioning also consume power).
As early as 2017, ASUS launched the B250 Mining Expert (B250 Mining Expert), and ASUS’s H370 in 2018 supports up to 20 graphics cards. However, there have been no relevant reports on the market for a mining machine that assembles 78 cards at a time like Simon Byrne. The GeForce RTX 3080 launched by Nvidia this year has been highly rated by high-end PC gamers. After the product was launched, it was sold out. Due to its excellent performance, many graphics cards were sold to crypto miners. According to a report by foreign media Bitcoin.com in November, Ethereum miners purchased Nvidia GPUs for as much as $175 million in the quarter.
Inka RTX 3080 was launched in September at a price of US$699, but due to hot sales and short supply, the current price has risen to US$1199 per piece (the domestic price is about more than 10,000 yuan). At today's prices, Byrne's installation would cost about $93,522.
According to TweakTown’s estimates, using the Ethash (Phoenix) algorithm, the computing power of a single GeForce RTX 3080 is about 83MH/S, which means that a graphics card can mine about 0.22236870 ETH per month. Therefore, 78 cards will mine 17.3 ETH per month! That works out to roughly $12,645 at the time of writing.
Excluding (estimated) electricity bills, Byrne can earn $10,200 a month from this homemade mining machine, or nearly $122,400 a year! The highest price of Ethereum when the market was at its best was $1,422. If the price of Ethereum goes higher in the coming year, the profit that this home-assembled mining machine can earn will be even higher! In addition, the residual value of first-level graphics cards like 3080 is very high. If they are no longer used for mining and resold, they can also achieve good performance in the secondary market. Therefore, some game enthusiasts sigh with emotion, no wonder so many graphics cards are bought by cryptocurrency miners!
