Can the NVIDIA GeForce RTX 4080 run Pythia-1.4b?

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

Pythia-1.4b on the NVIDIA GeForce RTX 4080

QuantFits?Max contextSpeedBeyond context
FP16 yes 159k 191.9-228.7 t/s ~10.4-12.4 (slow)
Q8 yes 180k 383.8-457.4 t/s ~20.9-24.9 (slow)
Q4 yes 190k 685.3-816.7 t/s ~37.2-44.4 (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 Pythia-1.4b?โ–ถ

Yes. At Q4 it generates ~685.3-816.7 tok/s and fits up to 190k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~37.2-44.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 190k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
