The most recent Linux display driver contains multiple lines of code that makes reference to AMD's Navi 10, Navi 12, Navi 14 and Navi 21 GPU variants. The Navi 10 silicon allegedly powers the Radeon RX 5700 XT and RX 5700, but the other Navi variants remain a mystery.

It's unclear at this point where the Navi 12, Navi 14 and Navi 21 will find their places in AMD's graphics cards. However, it's speculated that AMD could use the Navi 21 silicon in the Radeon RX 5800 graphics cards while saving the Navi 12 and Navi 14 dies for the Radeon RX 5600 and RX 5500 lineups, respectively. The Linux driver code specifically mentions the "P" and "M" suffixes for each Navi variant. The "P" suffix could stand for performance or power while the "M" suffix most likely refers to mobile.

The Navi 10, Navi 12 and Navi 21 silicons seemingly come in normal and Lite presentations. Although we're not completely sure, it's possible that the Lite variants could come with disabled Compute Units (CUs) and optimized for laptops. With a combination of the "P", "M" and Lite designations, we have as much as eight different Navi variants now. The code also reveals that only the Navi 10 Lite P silicon is on the B0 stepping while the remaining seven silicons are still on the A0 stepping.
