Sigh. IPC matter when you are comparing within the same architecture, as that means the comparative performance vs other cores of the same architecture ends up (somewhat simplified) as IPC * frequency. It is utterly irrelevant when comparing across architectures as the instruction sets are different. IPC matter when comparing Ryzen to Intel, and between A15 and A16, but it doesn't matter at all when comparing A15 to anything x86-based.
