A recent Linux driver update suggests that AMD will be adding a few new GPUs (on top of the recently announced Radeon RX 5500 and Radeon RX 5500M) to the Radeon RX family soon. The driver alludes to three new Navi 14 devices, which are presumed to be the Radeon RX 5500 XT, Radeon RX 5300, and Radeon RX 5300M. Their respective game clocks are 1717 MHz, 1448 MHz, and 1181 MHz.
We already know that the Radeon RX 5700, RX 5700 XT and RX 5700 XT 50th Anniversary Edition employ the Navi 10 XL, Navi 10 XT and Navi 10 XTX dies, respectively. Additionally, the listing also mentions the 1,625, 1,755 and 1,830 values, which effectively match the game clock speeds for the trio of Navi 10-powered graphics cards.
