"The M5 Max gets up to 40 GPU cores, a pair of media encoding/decoding engines, and a memory controller that provides up to 614 GB/s of memory bandwidth (note that everything in the GPU die seems to be doubled, implying that Apple is, in fact, sticking two M5 Pro GPUs together to make one M5 Max GPU)."
"These are, in fact, a new, third type of CPU core design, distinct from both the super cores and the M5's efficiency cores. They apparently use designs similar to the super cores but prioritize multi-threaded performance rather than fast single-core performance."
"At the bottom of the hierarchy, you still have "efficiency cores" that are tuned for low power usage. The M5 still uses six efficiency cores, and unlike the super cores, they haven't been rebranded since yesterday. These cores do help with multi-core performance, but they prioritize lower power usage and lower temperatures first."
Apple introduced significant architectural changes with the M5 Pro and M5 Max chips. The M5 Max features up to 40 GPU cores compared to M5 Pro's 20, dual media encoding engines versus one, and double the memory bandwidth at 614 GB/s. Apple rebranded performance cores as "super cores" across its M5 lineup. A new third CPU core type appears exclusively in M5 Pro and M5 Max, positioned between super cores and efficiency cores. These new performance cores prioritize multi-threaded performance rather than single-core speed, similar to AMD's approach with larger Zen cores. The M5 retains six efficiency cores designed for low power consumption in fanless devices.
