Frequently asked questions

Can the RTX 4070 Ti run DeepSeek R1 Distill Llama 8B?
The model needs about 6.7 GB and fits in the 11.6 GB available, with 5 GB to spare.
Which quantization should I use on the RTX 4070 Ti?
Q8_0 is the highest-precision quantization that fits entirely in VRAM at 8K context. ~10.2 GB / 11.6 GB.
What is the largest context on the RTX 4070 Ti?
At Q4_K_M, about 45K tokens fit entirely in VRAM with an f16 KV cache. A q8_0 KV cache roughly doubles that.
How fast is DeepSeek R1 Distill Llama 8B (RTX 4070 Ti)?
We estimate 63–86 tok/s (estimate, confidence low). Based on: memory bandwidth (504 GB/s) and model size.
