Can the NVIDIA GeForce RTX 4080 run DeepSeek-R1-Distill-Qwen-1.5B?

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

DeepSeek-R1-Distill-Qwen-1.5B on the NVIDIA GeForce RTX 4080

QuantFits?Max contextSpeedBeyond context
FP16 yes 147k 150.9-179.9 t/s ~8.2-9.8 (slow)
Q8 yes 175k 301.8-359.7 t/s ~16.4-19.6 (slow)
Q4 yes 187k 539-642.4 t/s ~29.3-34.9 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.

FAQ

Can the NVIDIA GeForce RTX 4080 run DeepSeek-R1-Distill-Qwen-1.5B?โ–ถ

Yes. At Q4 it generates ~539-642.4 tok/s and fits up to 187k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~29.3-34.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 187k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
