PCIe Gen 6 is... Abnormal | The Future is PCIe (Part 3), ft. Wendell of Level1 Techs

Wendell argues that PCIe has evolved from a simple expansion bus into the primary fabric for modern computing, subsuming networking and storage. As enterprise hardware shifts toward on-chip photonics and high-speed optical interconnects, these technologies are poised to eventually trickle down to consumer devices, offering lower latency and higher efficiency.
Key insight: PCIe Gen 6 is already being deployed in enterprise environments primarily to connect networking hardware directly to GPUs, a shift that is considered highly abnormal but necessary to handle 800 gigabit and 1.6 terabit data speeds.
