According to AMD's own performance numbers, the Radeon RX Vega 56 can hit up to 90 FPS while the Radeon RX 580 is enough for 60 FPS at 4K resolution, all thanks to the latest Radeon Software 17.9.3 driver. AMD went further saying that both the RX 560 and RX 570 are enough to get 63 FPS and 95 FPS at a more reasonable 1080p resolution.
The earlier report that came from Computerbase.de, showed that AMD RX Vega series graphics card managed to beat Nvidia's GTX 1080/1080 Ti graphics cards on almost all resolutions, offering much better overall performance.
The new benchmark slides were posted over at AMD's Radeon blog and as we wrote earlier, AMD will hopefully include some of those optimizations in future games as well.
