This architecture, while offering a significant improvement over older standards, eventually faced limitations in terms of scalability and speed. PCI 32 bits had a transport speed of 33 MHz, working at 132 MBps, while the 64-bit version, also at 33 MHz, could achieve 264 MBps. Even a faster PCI variant, running at 66 MHz, provided a throughput rate of 133 MBps in a 32-bit configuration. These speeds, while adequate for many early peripherals like sound cards or network interfaces, became a bottleneck for high-performance devices.

To address these speed limitations, the PCI Express slot was introduced.

* PCIe x4: Offering four times the bandwidth of a PCIe x1 slot, this configuration is suitable for a broader range of expansion cards, including some solid-state drives and high-speed network adaptersPCI Express (PCIe or PCI-e).

* PCIe x8: With eight lanes, the PCIe x8 slot provides even greater bandwidth, often found in professional-grade sound cards or network interface cardsPCIe Gen 4 vs. Gen 3 Slots, Speeds.

* PCIe x16: This is the longest and highest bandwidth PCIe slot availableGuide to Types of Expansion Slots and Add-In Cards. The PCI x16 slots are generally intended for use with Graphics Cards, which require substantial data transfer rates for rendering complex visuals.

It's important to note that PCIe cards can always operate in PCIe slots with the same or more lanes than the card.Peripheral Component Interconnect (PCI) For example, an x8 card can operate in a slot with x8, x16, or x32 lanes, though it will be limited by the number of lanes the card itself possesses. This backward compatibility ensures flexibility when upgrading or configuring systems.
