Can the RTX 5070 Mobile run Ornith-1.5-9B?
Just. Ornith-1.5-9B at Q4_K_M needs about 7.8 GB of the RTX 5070 Mobile's 8 GB, running at an estimated 37 tok/s. Keep context short and close other GPU apps.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 6 GB | 7.8 GB | Tight | ~37 tok/s |
| Q5_K_M | 7 GB | 8.8 GB | Too big | - |
| Q8_0 | 10 GB | 11.8 GB | Too big | - |
| FP16 | 19 GB | 20.8 GB | Too big | - |
Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the RTX 5070 Mobile's 384 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the GeForce RTX 5070 Mobile run Ornith-1.5-9B?
Just. Ornith-1.5-9B at Q4_K_M needs about 7.8 GB of the RTX 5070 Mobile's 8 GB, running at an estimated 37 tok/s. Keep context short and close other GPU apps.
How much VRAM does Ornith-1.5-9B need?
About 6 GB of weights at Q4_K_M, 10 GB at Q8_0 and 19 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Ornith-1.5-9B on the RTX 5070 Mobile?
Roughly 37 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the RTX 5070 Mobile's 384 GB/s memory bandwidth.
