RTX performance 3-4x
....a July 2020 update confirming that we're still to expect a huge 3-4x performance upgrade in ray tracing performance with the Ampere GPU architecture over the current-gen Turing GPU architecture.
If this is true, the next-gen Ampere-based GeForce RTX 3000 series cards will indeed makes "Turing look like Kepler trying to run DX12".

other sources have claimed that AMD’s Navi 2x graphics cards might get delayed to early 2021, at least the board partner models. If that turns out to be true, only reference cards will be available later this year which means there will likely be a shortage of units.
The source claims that the first validation sample for Big Navi was just recently sent to Shanghai for driver development. It appears that AMD’s US engineers have yet to visit the China-based manufacturing test labs to assess the final GPU performance. This means all previous leaks regarding Big Navi’s performance are bogus.
