AMD Infinity Fabric
AMD Infinity Fabric is a publicly named coherent interconnect used to assemble chiplet CPUs.
Overview
Infinity Fabric is AMD’s coherent on-package and multi-die interconnect, linking CPU core-complex dies to a central I/O die and, in multi-socket systems, across packages. Official EPYC architecture documents describe CCD–IOD GMI links and xGMI.
This listing records the chiplet fabric rather than individual Zen or EPYC product generations. Arm Chiplet System Architecture, already listed, is an industry standard rather than AMD’s production fabric. NVIDIA NVLink is a GPU-scale interconnect, not this CPU/GPU chiplet fabric. Link rates and socket mappings should be confirmed on AMD’s current architecture documentation.
Technical capabilities
Distinct from Arm CSA, UCIe IP, NVLink and Intel EMIB
