AMD is betting on strategic partners to one-up Nvidia — with 50-year-old Ethernet being at the heart of an alliance looking to promote a wider, more balanced ecosystem

Broadcom’s next-generation PCIe switches will support AMD’s socket-to-socket Infinity Fabric technology (also known as xGMI) – the company’s standard for boosting data transfer speeds between CPUs in a system. 

The Infinity Fabric interconnect, which is normally used in EPYC servers, can handle package-to-package connectivity, and behave as PCIe Gen5 for cards, as well as CXL. Now, with Broadcom supporting the standard, the technology will make its way into its PCIe switches. But the real secret weapon here is Ethernet, according to Serve the Home.
