One of the pillars on which NVIDIA's dominance in the accelerator world rests is NVLink, a high-speed interconnect that allows chips to communicate directly not only within a single node, but also beyond its borders. AMD is trying to respond to this by promoting the XGMI/Infinity Fabric, and in its preliminary review of the Instinct MI300, issues of red server topology were raised. Even then, at the time of the announcement of MI300, Broadcom announced support for this interconnect in future generations of its PCIe switches, and now the ServeTheHome resource has shared new details. XGMI will truly become switched, making it easier to scale systems based on AMD Instinct accelerators. The interconnect was officially named AFL (Accelerated Fabric Link).
