A next-generation AMD graphics architecture based on the GFX1250 IP under the CDNA series has been spotted online.
GFX1250 with CDNA Graphics Architecture Added to the Kernel Codebase: What Exactly are AMD's New Plans?
It should be no surprise to see newer architecture being deployed on the RDNA 4 GPU successors. Most reports suggest that AMD will likely utilize UDNA (Unified DNA), where it will combine the RDNA and CDNA architectures in order to combat NVIDIA's CUDA ecosystem. While this has been confirmed by various reports, the latest leak shows something different.
As spotted by @Kepler_L2, the new device ID added to the Kernel-level codebase is "GFX1250" with "CDNA" mentioned as the architecture for the device. If you are familiar with the device IDs of AMD GPUs, you must be aware of the respective IDs of RDNA 3, RDNA 3.5, and RDNA 4 architectures. For instance, the GFX1100 belongs to RDNA 3, and RDNA 3.5 is usually identified with GFX1150 and above, while RDNA 4 starts with GFX1200.
The newer "GFX1250" seems to be some kind of expansion of the RDNA 4, just like we had the GFX1150 as an expansion from RDNA 3 to RDNA 3.5. Moreover, the last time we checked, the "UDNA" architecture was denoted by "GFX13" (or GFX1300), so it looks like this IP will be used to power either the MI400 series before the company transitions to the GFX13/14 IP, which will be the start of the UDNA generation.
But again, the device ID mentions "CDNA", which is unlikely for RDNA 4 successors. So, is it talking about RDNA 4.5 or UDNA? It's unclear, and we can only speculate it's the RDNA 4 successor, but we can't guarantee that it's the next-gen UDNA architecture.
As far as integrated graphics are concerned, AMD has shown no plans to offer an RDNA 4 architecture on the CPUs/APUs, and the RDNA 3.5 will be carried over to Medusa Point as well. Hence, the GFX1250 won't likely make it to the CPUs/APUs.
