There’s a whole bunch of new information for AMD’s upcoming Navi based Radeon RX series that would feature the Navi 12 and Navi 14 GPUs by 3Dcenter. It looks like AMD would have a complete lineup versus the RTX SUPER series and the mainstream GTX cards with their own budget and high end options.

So we know about the existence of both AMD Navi 12 and Navi 14 GPUs. They have appeared on GPU databases from time to time and we also got to see some specifications and performance of the mainstream Navi 14 based variants. But we still don’t know how AMD is going to position these new GPUs and that is where 3DCenter’s forum member, Berniyh, comes in. The user dug deep into the latest Linux driver for AMD’s graphics cards and found IDs for both, the Navi 14 & Navi 12 GPU.
