Linux graphics driver driver exposure: AMD Vega 20 graphics card supports PCI-E 4.0



The PCI organization officially released PCI-E 4.0 in October last year, in which the transmission rate doubled to 16GT/s, and can provide up to 64GB/s bandwidth in X16 mode, and now it is driven by Linux. The first graphics card that supports the PCI-E 4.0 interface has appeared on the AMD Vega 20.


For this new Vega 20 graphics card, the specific model is the Radeon Pro Vega 20, with 16GB or 32GB of HBM2 memory, 4096 cores at the same time, the process will be upgraded to 7nm, and the highest performance is 35%. At the same time, this will be the world’s first graphics card to support PCI-E 4.0.


AMD’s upcoming next-generation server platform, the 7 nm Zen 2 EPYC (codenamed Rome), will also support PCI-E 4.0, and Samsung, in the SSD space, will also plan to support its next-generation flagship SSD to support the latest PCI-E 4.0 interface.
