Navi 12, 14, 21, and Lite variants of AMD's latest GPU range revealed in Linux driver code; RX 5800 could take on the GeForce RTX 2080

Data explorer Tum Apisak has unearthed some interesting references to Navi GPUs in Linux driver code. The code features Navi 10, Navi 12, Navi 14, Navi 21, Navi 10 Lite (possibly two revisions: A0 and B0), Navi 12 Lite, and Navi 21 Lite. Unsurprisingly, the discovery has led to considerable speculation as to what AMD has got planned for Navi’s future.

Most seem to have settled with the opinion that both Navi 10 and Navi 12 are aimed at the midrange/mainstream market, whereas Navi 14 could target the entry-level sector while Navi 21 takes on the high-end enthusiast base. The letters “P” and “M” are mentioned in the code along with the Navi GPUs, which seem likely to stand for “Performance” and “Mobile”, respectively.

Fortunately, a Reddit user called Voodoo2-SLI has compiled a table that features the already known data about the Navi 10-based Radeon RX 5700 series and what specifications the other three Navi GPUs could bring with them (see image at the bottom). Navi 14 GPUs could find their way into the Radeon RX 5500 series to challenge the GeForce GTX 1650 while the Navi 12-based Radeon RX 5600 cards might face Nvidia’s GeForce GTX 1660.

With the Radeon RX 5700 series set to take on the GeForce RTX 2060 and RTX 2070 it could be left to an RX 5800 series with Navi 21 GPUs to give Nvidia’s GeForce RTX 2080 and RTX 2080 Ti some proper competition. As for the “Lite” variants, it appears Redditors can’t agree on what this could signify, with laptop versions, APUs, and console processors all being suggested as possible explanations.
