Key points: PCIe offers the fastest data transfer rates, with each generation doubling the bandwidth of the previous one; PCIe x16 slots are typically used for graphics cards, while smaller slots accommodate other peripherals.

Unlike M.2, expresscard, mPCIe and USB-C Thunderbolt ports/slots, USB-C SS port (USB3 Gen2) does not carry PCIe signals so cannot be used for an eGPU.

PCIe x1: The smallest PCIe slot, which supports one lane of data transfer. It is often used for low-bandwidth peripherals, such as sound cards or Wi-Fi adapters.
