Infinity Fabric (IF) is a system of transmissions and controls that underpin most of AMD recent microarchitectures for both CPU (i.e., Zen) and graphics (e.g., Vega), and any other additional accelerators they might add in the future. The interconnections were first announced and detailed in April 2017 by Mark Papermaster, AMD's SVP and CTO.
The Infinity Fabric consists of two separate communication interconnections: Infinity Scalable Data Fabric (SDF) and the Infinity Scalable Control Fabric (SCF). The SDF is the primary means by which data flows around the system between end point (e.g. NUMA nodes, PHYs) whereas the SCF handles the transmission of the many miscellaneous system control signals. With those two interconnections, AMD can efficiently scale up many of the basic computing blocks.
