Eth's video card recommendation.
1, primary graphics card: 588, 1660s. A card's 588 is definitely a mine magic card. Those with better physique can overclock to 32, and the heat dissipation is good. The only disadvantage is that the power consumption is high, and the soft display is about 70w. Actually, it has to go up to 130w. At present, the currency price and difficulty are the fastest, although the new card is around 2400 and it is out of stock.
You can't go wrong by choosing 1660s for the entrance of the N card, with 29 magnesium grains and 3 Samsung grains1. The price is slightly higher than 588, and the computing power is slightly lower than 588, but fortunately the power consumption advantage is around 2500.
2.eth ore raising: 5600xt/5700xt 3060ti. 5600 and 5700 are well controlled in computing power and power consumption. The computing power of 43 and 56 is mainly affected by the current high premium, which basically increases the price by about 1200, resulting in a long return period, but as far as the current market is concerned, the price may become the norm.
The higher-priced 6800xt 3080 and 3090 are not recommended, because the cost of single computing power is too high, and unless there is a ready-made card, it will occupy more power graphic interfaces.
The difference between mining in Ethereum and mining in Bitcoin lies in:
1. Mining algorithm, equipment and computing power scale: Ethereum adopts Ethash encryption algorithm. In the process of mining, it is necessary to read the memory and store the DAG file. Different encryption algorithms lead to great differences between Bitcoin and Ethereum in mining equipment and computing power scale.
2. Proportion of mechanical and electrical fees of mining machine: ASIC mining machine has high computing power and large power consumption. For example, the latest Ant S 19Pro mining machine has a rated power consumption of 3250W and needs to consume 78 kWh of electricity every day.
According to the current currency price and the electricity price of 0.23 yuan in wet season, the electricity fee accounts for 30.68%. Other older generation bitcoin ASIC mining machines, such as ant T 17 series, generally account for more than 50% of electricity bills.
3. Mine machine custody: Earning the price difference is the main profit model of the mine. The more electricity you sell, the more money you earn in the mine. Bitcoin ASIC mining machine has high power consumption and relatively simple maintenance, so it is very popular in mines. When hosting, there are many mines to choose from.
The graphics card mining machine in Ethereum not only consumes less electricity, but also has a large volume. Compared with the bitcoin ASIC mining machine, the floor area ratio of ordinary graphics card machine reaches 1:3, which means that the space of three ASIC mining machines can only accommodate one graphics card mining machine.
