PCIe 4.0 graphics cards
prices on 212 modelsPCIe v4.0
— the latest version of the PCIe interface (as of early 2021) among widely used ones (newer standards are only being introduced into production). It surpasses the previous version in bandwidth by 2 times, providing about 2 GB/s per lane; accordingly, 16 lanes (PCIe 16x), typically used for video cards, deliver just under 32 GB/s.The use of PCIe 4.0 (as of the same 2021) is mainly characteristic of quite advanced video cards, including top-tier ones (although exceptions exist). However, it should be noted that for such an adapter to function properly, the connection slot on the motherboard must also support PCIe version 4.0 or higher.
