AMD is allegedly preparing a next generation GPU code named Navi 23 that's internally referred to as the 'NVIDIA Killer' and it's due to come out next year. We've heard whispers about this Navi 23 GPU in the techsphere as early as back in August of this year, but we've only gotten confirmation that it actually exists about a week ago when it crept up in a Linux code dump.

Thanks to a recent Linux driver we know that Navi 23 is only one of three different GPUs that AMD is building on TSMC's 7nm+ process node and the RDNA2 gaming graphics microarchitecture, the others being Navi 21 and Navi 22.
