TBH, I have an M2 pro (personal) and an M4 Pro (work) and I have never been able to tell the different in day to day use. That said, the only really intensive workload I have is photography/videography batch post-processing and I haven't tested that on my work machine. I'm disappointed Apple hasn't published any benchmarks comparing M5 to various M4 (or M3) variants.
They've only updated the base M5. Expect the Pro and Max updates to come early next year.
