// RUN — FITS
Can the Apple M4 Max 48GB run CLIP (ViT L/14@336px)?
Yes — here's how fast and up to what context, with real measured numbers.
CLIP (ViT L/14@336px) on the Apple M4 Max 48GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 625k | 501.7-605 t/s | ~9.2-11.1 (slow) |
| Q8 | yes | 631k | 1003.5-1210.1 t/s | ~18.4-22.2 (slow) |
| Q4 | yes | 633k | 1791.9-2160.8 t/s | ~32.8-39.6 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
