Frequently asked questions

Can the RX 9070 XT run Llama 2 7B?
The requested context (8,192 tokens) is longer than the model supports; 4,096 tokens were used. The model needs about 6.6 GB and fits in the 15.5 GB available, with 8.9 GB to spare.
Which quantization should I use on the RX 9070 XT?
Q8_0 is the highest-precision quantization that fits entirely in VRAM at 8K context. ~9.8 GB / 15.5 GB.
What is the largest context on the RX 9070 XT?
At Q4_0, about 4K tokens fit entirely in VRAM with an f16 KV cache. A q8_0 KV cache roughly doubles that.
How fast is Llama 2 7B (RX 9070 XT)?
We estimate 67–110 tok/s (estimate, confidence medium). Based on: same hardware, same model, same quantization, 18 benchmark(s), adjusted for context length.
