AMD Phoenix 2 CPU With Zen 4 and Zen 4c Hybrid Config Breaks Cover
Well apparently, there will also be a "Phoenix 2", and rather than being a straight successor to the original as the name would imply, it seems to be a "fork" of the design focused on lower-power applications. It has far fewer cores and a much smaller GPU, but the biggest change compared to the original recipe is the implementation of a hybrid architecture almost-but-not-completely like Intel's design.
Phoenix 2 is supposed to include just two full-fat Zen 4 CPU cores, while another four Zen 4C cores serve as low-power processors for background tasks. The RDNA 3 GPU has been cut back from six WGPs (12 CU) to just two (4 CU), and the TDP apparently drops from "35W+" to a maximum of 28W.
This more-or-less confirms the existence of Phoenix 2, but there's still a lot we don't know about its capabilities and why it exists. Presumably, it should be a significantly smaller chip than its bigger sibling, and the single-threaded performance could be extremely similar. As for multi-core, we don't know yet what changes have been made to Zen 4 to create Zen 4C, and we also don't know what kind of clocks the "C" cores will hit.
