On October 28, 2020, AMD introduced the long-awaited new-generation RDNA 2 video cards called: Radeon RX 6800, RX 6800 XT, RX 6900 XT. This time, AMD did not deviate from the established tradition of 2020 and the presentation of new products once again surprised and delighted miners and computer enthusiasts. And first of all, this concerns the release of video cards not only competing with the best solutions from Nvidia, but offering even greater performance in games and at a lower price (RX 6900 XT). Probably no one expected such a breakthrough from AMD. The last graphics card from AMD to impose a worthy competition in the top segment was the Radeon R9 290X, which was at or better than the GTX 780 Ti in performance. And this, for a second, was as much as 7 years ago in 2013. All subsequent AMD solutions in the top segment (Fury, Vega, Radeon 7) could only compete with Nvidia's average performance video cards (GTX 1070, RTX 2070). If the gaming performance of the new generation of video cards was shown at the presentation by AMD itself, then we need to figure out the performance in mining ourselves until the video cards go on sale on November 18. Until this happens, let's try to predict the hashrate of the RX 6800 and RX 6900 video cards in mining popular cryptocurrencies based on the official technical data available after the presentation.
