Can I run Swift Qwen3.8 27B on Radeon RX 7600?
Partial offload
Partial offload on your Radeon RX 7600: Q4_K_M at 4K context, 24 of 64 layers on the GPU and 10.4 GB in system RAM. Expect about 3.7–5.0 tok/s.

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%.
- Q4_K_M 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 4K context, not at the maximum context that still fits.
- About 24 of 64 layers stay on the GPU. 10.4 GB is read from system RAM.
