The document, which was published by Chip and Cheese, contains a compatibility table for Socket AM5, which is set to be AMD’s platform to support Zen 4 Ryzen. The table seems to contain an “On-Chip Graphics” section, listing three different kinds of AM5 processors, all equipped with “Hybrid GFX Support”. Unsurprisingly, the table doesn’t say exactly what kind of graphics cores will provide the GFX support, but it stands to reason that the Zen 4 CPUs may just be made to accommodate GPU cores based on the current RDNA2 graphics architecture. Such a possibility isn’t entirely far-fetched either; prior to this, another leaked roadmap reportedly showed AMD’s plans for its “Raphael” CPUs.
For the record, Raphael is the codename for AMD’s mainstream CPUs that are expected to launch as its Ryzen 7000 series next year. That same rumour, by the way, also hinted that we could see AMD come out another Zen 3-based Ryzen APU, but ones that boast more powerful Navi-based GPU cores. Instead of Vega. In any case, this is all still unconfirmed, so take this news with a pinch of salt.
