M4 Pro 64GB vs NVIDIA RTX 5090 Laptop 24GB for local LLMs
33 reports on the M4 Pro 64GB and 6 on the NVIDIA RTX 5090 Laptop 24GB
Which is faster for local LLMs?
On Qwen3.8 27B at 4-bit, the M4 Pro 64GB has 12.9 generation tokens/s (4 runs); prompt processing 126.2 tokens/s (4 runs); the NVIDIA RTX 5090 Laptop 24GB has 33.5 generation tokens/s (2 runs). Those are community reports whose engines and settings differ, so the gap is a rough sign, not a controlled measure of the two cards. Memory bandwidth, which caps how fast a card can write, is 3.3x higher on the NVIDIA RTX 5090 Laptop 24GB (273 GB/s on the M4 Pro 64GB, 896 on the NVIDIA RTX 5090 Laptop 24GB).

Measured on both
Generation and prompt processing speeds from plain runs (one device, one request, no speculative decoding, the whole model in the device's memory) of the same model size at the same bit class. Each side shows the engines and reported context behind its median. Context can mean a configured window or prompt depth, so these are community comparisons with differing settings. How to read these

Estimated by the calculator
The quant the calculator recommends for each card and its estimated speed at a 32,768-token context with 32 GB of system RAM, from memory bandwidth and the model's shape. Where a model was also measured above, the measurement wins.
