Intel Xe GPUs to use the new CXL interconnect for seamless scaling?

At its Interconnect Day, Intel presented CxL, a new interconnect for scaling CPUs over PCI Express 5.0 and beyond. While it's aimed at the datacenter market, WCCF Tech believes CXL may be part of a "coherent multi-GPU" future for Intel's upcoming Xe lineup. The site speculates CXL could solve a lot of the issues that plagued multi-GPU computing in the past, and that it would make it possible to seamlessly scale GPUs. Check out their article for all the details and speculation.

Intel discussed its brand new processor-to-processor interconnect, called the Compute Express Link (CXL), in detail at the ‘Interconnect Day 2019’ event yesterday. Whereas we have talked in depth about data centre interconnects before, this particular one works to connect devices across the physical PCIe port. The reason why I mention physical and not just PCIe is because while Intel CXL is designed to work over the physical PCIe port to ensure universal compatibility – it will not utilize the PCIe protocol but instead act as an alternative protocol to the same; one that is far more future proof and scalable than its archaic (soon-to-be) predecessor.
