PCIe Gen 4 aims to find adoption in  datacentre and ADAS equipment using GPUs, CPUs, NVMe, SSDs, NICs storage controllers, automotive cameras and Infotainment.

Applications such as artificial intelligence and machine learning, as well as traditional enterprise workloads utilizing networking, storage and offload processors, all benefit from the increased bandwidth of PCIe Gen 4 systems.

The family comprises switches from 96 lanes to 24 lanes, providing:

• High port density with up to 48 ports and 48 NTBs
• Flexible port bifurcation, from x2 to x16 lanes per port
• Switch partition capabilities with up to 24 switch partitions
• Advanced error reporting
• Error containment for surprise-plug and unplug to prevent system crashes
• Advanced diagnostics and debug features to identify, diagnose and fix problems
