Frequently asked questions

Can the RTX 3080 Ti run Mistral Nemo 12B Instruct?
The model needs about 9.4 GB and fits in the 11.6 GB available, with 2.2 GB to spare.
Which quantization should I use on the RTX 3080 Ti?
Q5_K_M is the highest-precision quantization that fits entirely in VRAM at 8K context. ~10.7 GB / 11.6 GB.
What is the largest context on the RTX 3080 Ti?
At Q4_K_M, about 21K tokens fit entirely in VRAM with an f16 KV cache. A q8_0 KV cache roughly doubles that.
How fast is Mistral Nemo 12B Instruct (RTX 3080 Ti)?
We estimate 72–102 tok/s (estimate, confidence low). Based on: memory bandwidth (912 GB/s) and model size.
