It's not really "rumored" to be so much as it is actually. The I/O dies are built at GlobalFoundries. The Epyc's larger I/O die is on GF's 14nm, and the consumer Ryzen I/O dies are GF's 12nm. https://www.anandtech.com/show/14525/amd-zen-2-microarchitecture-analysis-ryzen-3000-and-epyc-rome https://www.anandtech.com/show/14525/amd-zen-2-microarchitec...
