pcie x 16 slot It'll surely be a bottleneck if you're using a PCIe or card in a PCIe slot Simply because the slot doesn't have enough

The x16 slot provides the fastest bandwidth available on a motherboard, and your GPU needs these slots in order to operate at its full potential

pciex16 slot configuration Supports most 1, 2, and 3 slot graphic cards Designed for most fullmid ATX tower with at least 7 available PCI slots High quality material increases

In other words, using PCIe 4 means that the graphics card can benefit from a 39% wider bandwidth compared to PCIe 3 Benchmark results in 3DMark
