An alleged AMD Phoenix 2 hybrid APU has been spotted in the MilkyWay@Home database, featuring 2+4 CPU configuration. While the APU was note named, the "A70F80" CPUID apparently is a part of the Phoenix 2 lineup. According to the database entry, the APU in question has two standard Zen 4 and four power-optimized (low-power) Zen 4 cores, making such chip a sort a big.LITTLE-like hybrid configuration. It appears to support multithreading on all six cores.

While the entry does not confirm this is indeed the Phoenix 2 APU, it does matches some previous rumors. Such upcoming APU, as detailed by Tomshardware, is rumored to feature two Zen 4 cores with 2 MB of L2 and 4 MB of L3 cache, and four Zen 4c cores with 4 MB of L2 cache and 4 MB of L3 cache, which is a rather surprising configuration. It should also come with RDNA 3-based iGPU with up to 512 stream processors, and have DDR5/LPDDR5X memory support.Of course, as this is just an early database entry, you should take it with a rather big grain of salt. The entry suggest that the alleged Phoenix 2 APU has been in the MilkyWay@Home database since early March, indicating that the chip is under testing by someone in AMD or some partner, but we are still far away from the launch as the rumored date for Phoenix 2 APUs is set for the second half of 2023.
