| Specification | Transfer Rate | Bandwidth per Lane (x1) | Bandwidth per Slot (x16) | | :--- | :--- | :--- | :--- | | | 8.0 GT/s | ~985 MB/s | ~15.75 GB/s | | PCIe 4.0 | 16.0 GT/s | ~1,970 MB/s | ~31.5 GB/s |

In the days of PCIe 1.0 and 2.0, the standard used . This meant for every 8 bits of data, 2 bits of overhead were added to ensure clock recovery. This resulted in a 20% efficiency penalty. pci express 4.0 specification pdf

For engineers, the spec is a rigorous guide on managing channel loss and equalization. For consumers, it was the spark that ignited the high-speed storage era. As we look toward PCIe 5.0 and 6.0, PCIe 4.0 remains the current "sweet spot" of stability and performance—a mature standard that has successfully delivered the theoretical bandwidth of the PDF into the reality of the hardware. | Specification | Transfer Rate | Bandwidth per
