Ethereum, a popular cryptocurrency for miners, uses the Dagger-Hashimoto mining algorithm or simply ETHash, for which a special file must be loaded into the memory of the video card - DAG file. He, in turn, tends to increase in size after a certain period of time, called epochs. As of July 22, 2020, there is an epoch 350 on the Ethereum network, and the DAG file size for this epoch is 3.73Gb. In 2015, when the Ethereum cryptocurrency had just appeared, at the zero epoch the DAG file was exactly 1Gb, so in 2015 video cards with 2Gb video memory could mine this cryptocurrency, but already in 2016 miners with such video cards began to receive the message "Creating one big buffer for the DAG" symbolizing the lack of video memory for creating and storing a DAG file in the video memory of video cards with 2Gb. In 2018, the same fate befell the owners of video cards with 3Gb video memory, and in 2020, as you might have guessed, 4Gb video cards AMD RX470, RX480, RX560, RX570, RX580 and Nvidia GTX1050Ti, GTX 1650, GTX 1650 Super will finally leave Ethereum mining.
