Frequently asked questions

Can the RTX 6000 Ada run Gemma 2 27B IT?
The model needs about 19.6 GB and fits in the 46.6 GB available, with 27 GB to spare.
Which quantization should I use on the RTX 6000 Ada?
Q8_0 is the highest-precision quantization that fits entirely in VRAM at 8K context. ~31.6 GB / 46.6 GB.
What is the largest context on the RTX 6000 Ada?
At Q4_K_M, about 8K tokens fit entirely in VRAM with an f16 KV cache. A q8_0 KV cache roughly doubles that.
How fast is Gemma 2 27B IT (RTX 6000 Ada)?
We estimate 37–51 tok/s (estimate, confidence low). Based on: memory bandwidth (960 GB/s) and model size.
