Friendly internet stranger’s input:

- you don’t get GPU acceleration just by using unified memory. Llama.cpp still only uses the CPU on Apple Silicon chips.

- the difference in tokens/sec is likely attributable to memory bandwidth. Mac Studios with the base Max chip have 400 GB/s memory bandwidth compared to around 50 GB/s for the Ryzen 5000 series CPUs
