How you come to that conclusion?? Navi is super-good, its midrange 200mm2 gpu will beat geforce 2070 a 445mm2 gpu. But Navi is on 7nm while geforce is on 12nm. When Nvidia launches their gpus on 7nm I expect navi to still be superior on mm2/performance but a bit lower on effiency/performance. We shall see
It's AMD, sucked for a long time and would not recommend anyone to buy them. Only in consoles because they are cheap, at the end of the day they need to spend money to develop something new.
Beating 2070, nope.
