Can the RTX 5070 Ti Mobile run OTel-2.0-LLM-31B-IT-QLoRA?
No. OTel-2.0-LLM-31B-IT-QLoRA needs about 19.8 GB at Q4_K_M (weights plus 1.8 GB runtime overhead), and the RTX 5070 Ti Mobile has 12 GB, so it won't fit without offloading layers to system RAM, which is far slower.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 18 GB | 19.8 GB | Too big | - |
| Q5_K_M | 22 GB | 23.8 GB | Too big | - |
| Q8_0 | 33 GB | 34.8 GB | Too big | - |
| FP16 | 63 GB | 64.8 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 Ti Mobile's 672 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 Ti Mobile run OTel-2.0-LLM-31B-IT-QLoRA?
No. OTel-2.0-LLM-31B-IT-QLoRA needs about 19.8 GB at Q4_K_M (weights plus 1.8 GB runtime overhead), and the RTX 5070 Ti Mobile has 12 GB, so it won't fit without offloading layers to system RAM, which is far slower.
How much VRAM does OTel-2.0-LLM-31B-IT-QLoRA need?
About 18 GB of weights at Q4_K_M, 33 GB at Q8_0 and 63 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is OTel-2.0-LLM-31B-IT-QLoRA on the RTX 5070 Ti Mobile?
It doesn't fit in the RTX 5070 Ti Mobile's memory, so speed depends on how many layers you offload to system RAM - typically single-digit tokens per second or lower.
