Can the NVIDIA GeForce RTX 5080 run Pythia-410m?
Yes — here's how fast and up to what context, with real measured numbers.
Pythia-410m on the NVIDIA GeForce RTX 5080
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 189k | 854.6-1018.5 t/s | ~35.6-42.4 (slow) |
| Q8 | yes | 195k | 1709.3-2037.1 t/s | ~71.2-84.9 (slow) |
| Q4 | yes | 198k | 3052.3-3637.6 t/s | ~127.2-151.6 (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 5080 run Pythia-410m?▶
Yes. At Q4 it generates ~3052.3-3637.6 tok/s and fits up to 198k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~127.2-151.6 tok/s.
How much context fits?▶
At Q4, up to about 198k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
