AMD RDNA 3 architecture GPU will be equipped with DCN 3.2
Coelacanth-Dream recently discovered that AMD’s Linux software engineers are adding new devices in the latest Linux patch, including Navi 31, Navi 32, and Navi 33 based on the RDNA 3 architecture, as well as new APUs. AMD is clearly in the pre-release cycle for the next GPU architecture, and new GPU support will be gradually deployed in the Linux kernel, graphics drivers, and libraries.
The IDs of Navi 31, Navi 32, and Navi 33 are GFX1100, GFX1102, and GFX1101 respectively, and GFX1103 should be a new generation of APU codenamed Phoenix Point. Among them, Navi 31, Navi 32, and Navi 33 will be upgraded from the existing DCN 3.0 to DCN 3.2.1, and the Phoenix Point APU will be DCN 3.1.4. New data shows that the RDNA 3 architecture integrated graphics used by the APU will not have Infinity Cache, which means that Infinity Cache is likely to be limited to the RDNA 3 architecture GPU used by discrete graphics cards.
Coelacanth-Dream noted that DCN 3.2.1 and DCN 3.1.4 still support a maximum of four displays. This means that no matter whether it is a discrete graphics card or integrated graphics, the GPU based on the RDNA 3 architecture will not support more than four monitors. RDNA 3 architecture GPU in the Linux system, there is no difference between DCN 3.2.1 and DCN 3.1.4.
There have been rumors that Intel intends to significantly increase the number of EUs configured for Meteor Lake next year, up to 192. This makes it necessary for AMD to find a way to increase the number of CUs in the APU to improve performance as much as possible to compete with Intel’s new generation of chips. As for the Navi 3x series GPU based on the RDNA 3 architecture, it is expected to be released within this year, and the competitor is NVIDIA’s GPU based on the Ada Lovelace architecture.
