I just wonder if this isn't prototype A16 SoCs that are meant for future iPhone and iPad Pro usage? Remember they were discussing future IPad Pros returning to A SoC?I don't see how launching an M2 chip in the 13" MBP makes any sense. Months after launching new flagship 14 and 16" machines? Why wouldn't they put it in those?
A15 has two high-performance cores and four energy-efficient cores, along with GPU is five core. Wouldn't be a stretch to add 2 cores to the CPU and double the GPU cores to be utilized.
