PRO W7800 strengths and weaknesses
Strengths
- Runs 35B MoE models: Qwen3.6 35B A3B at 61.0 tok/s in 22 GB
- Room for long context: Qwen3.8 27B at Q4 uses 17.9 GB, leaving 14.1 GB free
Weaknesses
- 70B models don't fit: Llama 3.3 70B Instruct needs 51.3 GB at Q4 vs 32 GB here
- Slow prompt reading: A 4K-token prompt on Qwen3.8 27B waits 11.4 s for the first token
- ROCm, not CUDA: No FP8 weights; MXFP4 only through llama.cpp, not vLLM
Output speed depends on memory bandwidth (576 GB/s). Grey rows need more than 32 GB.
