Some AMD Ryzen 5 7600X 6-core/12-thread processors could be made with dual-CCD "Raphael" packages, reveals a de-lidding feat by der8auer. This is functionally the same processor as a single-CCD package, all 6 CPU cores are located on just one of the two CCDs; while the other CCD is completely disabled. This wouldn't be the first time that AMD carved out low core-count SKUs using dual-CCD MCMs, we've seen instances of such dual-CCD Ryzen 5 and Ryzen 7 processors from past generations, such as the Ryzen 3000 "Matisse" and Ryzen 5000 "Vermeer." Normally, the Ryzen 5 and Ryzen 7 SKUs are based on a single-CCD package, with the substrate physically lacking a second CCD. The IHS is small and sturdy enough to not need the second CCD as a structural support. This leads us to speculate that the 7600X is being harvested out of dual-CCD packages that have been produced surplus to demand.
 
It makes sense not to waste any surplus CPUs due to the cost of manufacturing.
