Apple M3 Pro
Apple M3 Pro has 18 GB of unified memory at 154 GB/s — about 12.56 GiB usable after driver and compositor overhead. 1854 of 2118 indexed models fit at 8K context with q4_0 KV. Note only 14 GB of its 18 GB is allocatable to the GPU.

Speed is modeled, not measured: decode is memory-bandwidth bound, so tokens per second is bytes read per token against achievable bandwidth. Mixture-of-experts models carry a wider band because only the routed experts are read each step, and few have been measured publicly.
Measured on this card
| Workload◍ | Median | Middle 50% | Runs |
|---|---|---|---|
| Prompt processing | 339.31 tok/s | 305.24–343.17 | 7 |
| Text generation | 17.53 tok/s | 16.95–30.51 | 7 |
Aggregated from community-submitted runs, so the spread is wide by nature — it covers different models, resolutions, step counts and settings, not one controlled configuration. Read the middle 50% rather than the median alone. These figures are reproduced with attribution from llama.cpp-discussion-4167.
Questions people ask
- What AI models can a Apple M3 Pro run?
- 1854 of 2118 indexed open-weight models fit a Apple M3 Pro at 8,192 context with q4_0 KV cache, the largest being GLM-4-32B-0414-Korean-Culture at I1-IQ3_XS. That covers text, vision-language, image, video and speech models.
- How much usable memory does a Apple M3 Pro actually have?
- Its nameplate is 18 GB, but about 12.56 GiB is available to a model once driver and compositor overhead is accounted for, and only 14 GB of the pool can be allocated to the GPU at all.
- Is a Apple M3 Pro fast for local AI?
- Its memory bandwidth is 154 GB/s, and that figure — not teraflops — is what governs token generation speed. Capacity decides what you can run; bandwidth decides how fast it runs.
