NVIDIA's next-gen AD102 GPU is currently being tested for the GeForce RTX 4090 graphics card, as reported by Kopite7kimi.

There has been speculation that NVIDIA might go for the GeForce RTX 50 series naming scheme instead of the expected GeForce RTX 40 series branding but it looks like Kopite7kimi has stated NVIDIA's decision to stick to the 40 series naming scheme. Other than that, one big milestone is that NVIDIA may already have started testing and evaluating its flagship Ada Lovelace GPU, the AD102, which will power a series of graphics cards such as the RTX 4090 and the RTX 4080.
