David Kumar, AMD's Chief Financial Officer, recently confirmed that Team Red's "Big Navi" RDNA2 parts will arrive on PC before the launch of the ninth-gen Sony PlayStation 5 and Microsoft Xbox Series X consoles. According to Kumar, Big Navi will be a "halo" product, indicating price and performance levels well above the current US$399 AMD Navi RX 5700 XT.
Leaks indicate that Big Navi is a 64 CU part not dissimilar to the GPU found in the Xbox Series X. Considering what we know about Navi performance scaling, this would imply performance levels a good 10-15 percent above the NVIDIA GeForce RTX 2080 Ti.
This would make "Big Navi" the first AMD graphics card to deliver a true 4K/60 FPS gaming experience on PC. While it will almost certainly be faster and cheaper than NVIDIA's reigning US$1400 graphics king, the impending launch of NVIDIA's Ampere architecture and the GeForce RTX 3080 Ti and GeForce RTX 3080, will likely block AMD from claiming the performance crown.
NVIDIA's enterprise Ampere reveal showcased a truly massive card. Even if consumer designs are significantly cut down, the GeForce RTX 3080 Ti will almost certainly deliver a major performance upgrade relative to the GeForce RTX 2080 Ti, not to mention enhanced Tensor core and ray-tracing performance.
Nevertheless, users looking to build an all-AMD machine should be able to pair Ryzen 4000 desktop processors with Big Navi to take on the PlayStation 5 and Xbox Series X before 2020 ends.
