Common questions
Answered from the verified figures on this page rather than general guidance.
Apple M4 Max (64GB) has more memory bandwidth — 546 GB/s against 273 GB/s. That usually helps high-refresh 1440p and 4K once VRAM is sufficient for your settings. Still verify with dated independent tests for the games you play.
Apple M4 Max (64GB) — 48GB usable against 18GB on Apple M4 Pro (24GB). Extra memory helps texture mods, video timelines, and 3D scenes before it helps esports frame rates.
Apple M4 Max (64GB). With 48GB usable against 18GB it additionally holds Qwen 3 32B, Llama 3.3 70B at Q4.
Apple M4 Max (64GB), at 546 GB/s against 273 GB/s — roughly 2.0× the memory bandwidth. Bandwidth is the practical ceiling on token throughput once a model fits, but it only matters if the model fits in the first place.
Apple M4 Max (64GB) can, at Q4 — a 70B model needs about 42GB including runtime overhead. Apple M4 Pro (24GB) does not have the memory. Expect little headroom for long context.
If one card holds a model the other cannot, that capacity difference usually outweighs a bandwidth advantage. A model that spills to system memory can be substantially slower, but the actual impact depends on the backend, transfer path, context, and workload.
