Intel Z690 Motherboard and Chipset Overview – Tom’s Hardware

Outside of the new socket, one of the most significant differences in the new Z690 chipset is native PCIe 5.0 support, which doubles the available bandwidth to 64 GBps. While we’re a ways away from PCIe 5.0 hardware, and even further from when that type of throughput is needed, the bandwidth is here. AMD was first to market with PCIe 4.0; now it’s Intel’s turn to lead the bleeding edge with PCIe 5.0. With all of this available bandwidth, you can run more devices (M.2 slots, for example) off the CPU-connected PCIe lanes and not lose performance from your graphics card. There are also faster lanes on the chipset, allowing devices to use fewer lanes to achieve their full performance, increasing board makers’ flexibility with where to attach items.
