Common questions
Answered from the verified figures on this page rather than general guidance.
GeForce RTX 5090 has more memory bandwidth — 1792 GB/s against 546 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 32GB on GeForce RTX 5090. Extra memory helps texture mods, video timelines, and 3D scenes before it helps esports frame rates.
Apple M4 Max (64GB). With 48GB usable against 32GB it additionally holds Llama 3.3 70B at Q4.
GeForce RTX 5090, at 1792 GB/s against 546 GB/s — roughly 3.3× 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. GeForce RTX 5090 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.
