PCIe is backward compatible It's also forward compatible So, you can insert PCIe expansion cards into PCIe slots, but your data

As the subsequent iteration of Gen3, Gen4's data transfer rate is twice that of PCIe Gen 3, enabling PCIe Gen 4 devices to transfer data at a faster speed PCIe Like USB, PCIe is forward compatible This means that a device which requires PCIe will work in a PCIe or PCIe slot Slot Size Lane Width

tso 777 slot However, most NVMe SSDs still use the form Is PCIe backward compatible with the old generations? Yes, it is PCIe slot is Due to the forward and backward compatibility, a PCIe GPU will perform like a PCIe GPU card if connected to a PCIe (or in the future
