M5 Pro and M5 Max are surprisingly big departures from older Apple Silicon
Apple is using more chiplets and three types of CPU cores to make the M5 family.

TL;DR
- The M5 Pro and M5 Max chips utilize a new Fusion Architecture, joining two chiplets into a single processor.
- A third type of CPU core, a "performance core," is introduced, distinct from "super cores" and "efficiency cores."
- The M5 Pro includes up to 20 GPU cores, while the M5 Max features up to 40 GPU cores.
- The M5 Pro offers up to 307 GB/s of memory bandwidth, while the M5 Max provides up to 614 GB/s.
- Apple's "super cores" are a rebranding of previous "performance cores," while the new "performance cores" prioritize multi-threaded performance.
- The M5 generation relies on architectural improvements and memory bandwidth increases for its expected performance boost over previous generations.
