PCIe Gen 4/5/6
Overview
PCIe Gen 4 was introduced in 2017 and doubled the bandwidth of the previous Gen 3 standard, providing up to 16 GT/s (giga transfers per second) of data transfer rate. PCIe Gen 5, released in 2019, further increased the bandwidth to 32 GT/s, while the upcoming PCIe Gen 6 released in 2021, will push the limits to 64 GT/s. These advancements enable faster data transmission for high-performance computing, storage, and networking applications.
