At Computex AMD showed off their Navi graphics card for the first time, which was the Radeon RX 5700. Some internet users have done some digging and found out that AMD has certified as many as 5 different Navi graphics cards in Korea. This definitely points to their being more than just one card in the Radeon RX 5000 series.
While this does not necessarily confirm that there will be 5 cards in the Radeon RX 5000 series, it is more than likely that we will see at least more than just the Radeon RX 5700. AMD has always released at least two cards based on the same GPU at one time, and from everything we’ve heard there will be at least two Radeon RX 5000 series cards.
AMD already demoed the Radeon RX 5700 at Computex, which they showed it going head to head against NVIDIA’s GeForce RTX 2070 and beating it.
