// RUN โ€” FITS

Can the Apple M4 Max 48GB run DARTS (second order) (PTB)?

Yes โ€” here's how fast and up to what context, with real measured numbers.

DARTS (second order) (PTB) on the Apple M4 Max 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 636k 8071.3-9733 t/s ~147.8-178.3 (slow)
Q8 yes 636k 16142.6-19466.1 t/s ~295.7-356.5 (slow)
Q4 yes 636k 28826.1-34760.9 t/s ~528-636.6 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.

FAQ

Can the Apple M4 Max 48GB run DARTS (second order) (PTB)?โ–ถ

Yes. At Q4 it generates ~28826.1-34760.9 tok/s and fits up to 636k context; beyond that it spills to SSD swap and slows to ~528-636.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 636k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
