AMD Navi 31 GPUs based on the RDNA 3 graphics architecture are allegedly going to offer PCIe Gen 5.0 x16 support for the high-end Radeon RX 7000 series.

The latest information regarding the high-end Radeon RX 7000 graphics card lineup comes from Kepler_L2 who has been digging RDNA 3 GPU information through various drivers and patches. Now, the same leaker is reporting that AMD's Navi 31 GPU, the flagship for the Navi 3X lineup, is going to feature support for PCIe Gen 5.0 x16 lanes. I wouldn't be surprised to see AMD first to the PCIe Gen 5.0 standard considering they were the first to both PCIe Gen 4.0 (RX 5000 series) and PCIe Gen 3.0 (HD 7000 series).
