For AI / LLM Use
Limited VRAM restricts you to 7B quantized models. 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?
- 7B Q6_K, 14B Q3_K (tight)
- 7B Q4_K_M only
Estimated Performance
Generation: ~17 tokens/sec
Prefill: ~159 tokens/sec
Recommended Quantisations
- Q4_K_M for 7B models
- Q3_K for larger experiments
Pros & Cons
Pros
- Only 132W TDP: power efficient
- RDNA2 architecture: supported by current ROCm stacks
- Consumer card: easy to install, display output
Cons
- Only 8GB usable VRAM: limited to small models
- Low memory bandwidth: slower token generation
- ROCm and CUDA-first framework compatibility should be checked before purchase
