AMD is still cooking its next-gen RDNA 3 architecture and flagship Navi 31 GPU, where we should see the flagship Navi 31-based Radeon 7000 series graphics card, which will have next-gen PCIe 5.0 x16 support.

I think it’s a foregone conclusion even before a leaker “Kepler_L2” giving the Chuck Norris thumbs up to PCIe 5.0 x16 support on Navi 31. AMD will be launching its next-gen Zen 4 architecture for the CPU side of its business later this year, with new X670-based motherboards rocking DDR5 + PCIe 5.0 support.

Intel had DDR5 first on its new Z690-based motherboards ready for its new 12th Gen Core “Alder Lake” CPUs, and now AMD will not only catch up with DDR5 but also introduced PCIe 5.0. Yes … Intel also has PCIe 5.0 connectivity on its flagship Z690-based motherboards, but they have no PCIe 5.0-ready GPU. AMD will have a PCIe 5.0-ready GPU (Navi 31) and a PCIe 5.0-ready chipset, right in time for the holidays.

The news of Navi 31 packing PCIe 5.0 support from leaker “Kepler_L2” is from his work looking through drivers and patches for the upcoming RDNA 3-based GPU architecture.

AMD launched the first PCIe 4.0-based GPU with its RDNA-based Radeon RX 5000 series, and the first PCIe 3.0-based Radeon HD 7000 series GPUs … and now into the warm, huge bandwidth arms of PCIe 5.0 x16 which offers a huge 128GB / sec (up from 64GB / sec on PCIe 4.0 x16 and 32GB / sec on PCIe 3.0 x16).
