AMD is rumored to be working on 16-core Zen4 laptop processors. AMD Raphael is the company's next-generation desktop silicon, which includes cores built on the Zen4 microarchitecture. Although there has been no official confirmation of the number of cores in the desktop version, it appears that we are now learning how many cores exist in the mobile version.

Known as Raphael-H, it will coexist alongside the future lineup of Phoenix APUs, which will be released after the Rembrandt APU lineup from the 6000 series. As many as 16 cores are available in this mobile variation of the upcoming desktop Raphael CPUs, which are based on the Zen 4 architecture. 

The timing for these processors is the most perplexing aspect of the situation. The Rembrandt APUs (6000 series) are the first to be introduced, followed by the Raphael-H and Phoenix mobile CPUs.  We do not yet know the specifics of the processors, such as their final core configurations, we do know that they will both include RDNA2 graphics and will support DDR5 memory technology. The series would compete against Intel Raptor Lake Mobile, which is not projected to be released until the end of 2022 or early 2023, which would put it a year after Alder Lake Mobile in the market.
