Frequently asked questions

Can the RTX 4080 SUPER run Mistral 7B Instruct v0.3?
The model needs about 5.9 GB and fits in the 15.5 GB available, with 9.6 GB to spare.
Which quantization should I use on the RTX 4080 SUPER?
Q8_0 is the highest-precision quantization that fits entirely in VRAM at 8K context. ~9.2 GB / 15.5 GB.
What is the largest context on the RTX 4080 SUPER?
At Q4_K_M, about 32K tokens fit entirely in VRAM with an f16 KV cache. A q8_0 KV cache roughly doubles that.
How fast is Mistral 7B Instruct v0.3 (RTX 4080 SUPER)?
We estimate 95–135 tok/s (estimate, confidence low). Based on: memory bandwidth (736 GB/s) and model size.
