We’re just a few days away from the launch of the new AMD RX 5700 XT and Radeon RX 5700 graphics cards on Sunday, and we can’t wait to talk about how the new Navi RDNA GPUs perform. But we’re not allowed yet. What we can say, however, is that the Navi 10 silicon inside them is being joined by upcoming Navi 14 chips. Well, according to AMD’s own Linux submissions anyways. Yesterday kernel patches for the as-yet unannounced Navi 14 GPU were posted, presumably in order to get into the new Linux 5.3 kernel update cycle instead of having to wait for the 5.4 version. AMD has already provided Navi 10 support for the Linux 5.3 kernel that’s getting merged in Autumn of this year, enabling the RX 5700-series cards, but you will still be able to use the new Navi-powered Radeon GPUs on Linux distributions that are compatible with the Radeon Software for Linux software. Which end of the graphics card stack the Navi 14 GPUs will sit is still up for debate. Traditionally we’ve seen AMD launch with the high-end parts first, leaving the lower-spec cards to backfill its graphics card families. And that would indicate the 5500- and 5600-series GPUs mentioned in the latest Sapphire card registration could be the target for these new patches.
