Can I run Qwen2.5 32B Instruct on Radeon RX 7800 XT?
Heavily degraded
Heavily degraded fully on your Radeon RX 7800 XT at IQ2_S, 8K context, about 27–37 tok/s. Weights 9.67 GB plus 2.00 GB of KV cache — 12.1 GB of 14.7 GB usable. Up to 16K context still fits.

Assumptions
- Estimate from memory bandwidth, not a benchmark. Decode speed uses 55–75% of peak bandwidth.
- KV cache is FP16. Engine overhead assumes llama.cpp (0.3 GB + 1% of the weights). Ollama is closer to 0.9 GB + 3%, LM Studio closer to 1 GB + 3%.
- IQ2_S size is the real GGUF file size from Hugging Face.
- 0.5 GB is reserved because this GPU also drives a display, then 5% of the rest is left free.
- Speed is quoted at 8K context, not at the maximum context that still fits.
- This quant is IQ1 or IQ2. It can load, but quality is heavily degraded, so it is left off best-fit lists.
