For AI / LLM Use
Entry-level for local AI. Handles 7B-8B models well. Slower generation, usable but not snappy. Verify ROCm support for the exact framework and operating system you plan to use.
What Models Can It Run?
- 14B Q4_K_M, 7B full precision
- 7B Q6_K, 14B Q3_K (tight)
- 7B Q4_K_M only
Estimated Performance
Generation: ~29 tokens/sec
Prefill: ~236 tokens/sec
Recommended Quantisations
- Q4_K_M for 14B (tight fit)
- Q6_K or Q8 for 7B models
Pros & Cons
Pros
- RDNA2 architecture: supported by current ROCm stacks
- Consumer card: easy to install, display output
Cons
- 12GB usable VRAM: may need quantization for 30B+ models
- Moderate memory bandwidth: not the fastest for inference
- ROCm and CUDA-first framework compatibility should be checked before purchase
