Can the NVIDIA GeForce RTX 5070 run Janus 1.3B?

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

Janus 1.3B on the NVIDIA GeForce RTX 5070

QuantFits?Max contextSpeedBeyond context
FP16 yes 106k 188.7-224.9 t/s ~11.2-13.4 (slow)
Q8 yes 126k 377.4-449.7 t/s ~22.5-26.8 (slow)
Q4 yes 134k 673.8-803.1 t/s ~40.1-47.8 (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 5070 run Janus 1.3B?โ–ถ

Yes. At Q4 it generates ~673.8-803.1 tok/s and fits up to 134k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~40.1-47.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 134k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
