On July 2, 2019, Nvidia announced an updated line of its RTX video cards with the SUPER prefix: RTX2060 Super, RTX2070 Super, RTX2080 Super. The slightly improved performance on the same 12nm process technology does not give rise to drastically new advantages over last year’s RTX cards. The main advantage of the new line is the starting price, which, together with the increased performance, will give miners a shorter payback period when using this equipment in cryptocurrency mining. The novelty will be on sale only in a week on July 9, 2019, so the real tests in the mining of Super RTX video cards from Nvidia are not yet available. In this connection, we will compare the technical characteristics of different models of RTX video cards and try to mathematically try to predict the hashrate of new products on popular mining algorithms.

* Hashrate video cards with Super index is calculated and may not coincide with the real performance in mining.
It is worth noting that the 2070 Super and 2080 Super power consumption remained at the same level as the regular, less powerful versions of the RTX. From this we can conclude that in the mining, the energy efficiency of new products will be 10-15% better. The 2060 Super power consumption has increased by 10W from 165 to 175W, which is likely due to an increase in memory from 6Gb to 8Gb and a more advanced GPU supporting 256-bit data bus for memory.
