"Computer systems are about to get a whole lot faster. For almost two decades PCIe has been the data interconnect standard knitting together CPU, storage, networking, IO and GPUs in PCs to HPC systems. In that timeframe it has delivered a doubling of bandwidth every three years on average. Today, virtually all computer systems are based on PCIe 3.0 delivering 8GT (gigatransfers per second) per lane resulting in 32GB/s bandwidth in a standard 16 lane connection (duplex).

This year, starting at the high end of the market, a transition will begin toward systems based on PCIe 4.0. The interconnect speed will double to 64GB/s in a 16 lane connection. The speed increase will provide an improvement across the range of HPC applications such as AI/ML, scientific simulation, big data analytics, high resolution visualization and rendering, and genomics analysis..."
