Can the RTX 3080 Ti run Unlimited-OCR?
Yes. Unlimited-OCR fits the RTX 3080 Ti's 12 GB at Q4_K_M (about 3.8 GB needed), running at an estimated 261 tok/s. There's room for up to FP16 if you want higher quality.

Unlimited-OCR (3.3B) on 12 GB
| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 2 GB | 3.8 GB | Fits easily | ~261 tok/s |
| Q5_K_M | 2 GB | 3.8 GB | Fits easily | ~261 tok/s |
| Q8_0 | 4 GB | 5.8 GB | Fits easily | ~131 tok/s |
| FP16 | 7 GB | 8.8 GB | Fits | ~75 tok/s |
Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the RTX 3080 Ti's 912 GB/s bandwidth (XiongjieDai/GPU-Benchmarks-on-LLM-Inference). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the NVIDIA RTX 3080 Ti run Unlimited-OCR?
Yes. Unlimited-OCR fits the RTX 3080 Ti's 12 GB at Q4_K_M (about 3.8 GB needed), running at an estimated 261 tok/s. There's room for up to FP16 if you want higher quality.
How much VRAM does Unlimited-OCR need?
About 2 GB of weights at Q4_K_M, 4 GB at Q8_0 and 7 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Unlimited-OCR on the RTX 3080 Ti?
Roughly 261 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the RTX 3080 Ti's 912 GB/s memory bandwidth.
