A few days ago, a rumor circulated that AMD was prepping EPYC 4004-series processors based on the Zen 4 architecture in the AM5 form factor. Today, an enthusiast from ChipHell forums said that he had spotted these CPUs on eBay. Since the information comes from an unofficial source, throw a pinch of salt over the information.
Since AMD's EPYC 4004-series processors come in AM5 packaging, we believe they will replicate core count specifications from their desktop brethren, so do not expect them to have more than 16 cores or feature an EPYC I/O die. After all, packaging caters to particular CCDs and IODs in terms of physical dimensions, power supply, and I/O capabilities.
