Puget Systems tests dual AMD Radeon AI PRO R9700 for local LLM inference

Puget Systems benchmarked two AMD Radeon AI PRO R9700 GPUs (32GB each, $1,880 per card) for local LLM inference, finding stock vLLM multi-GPU doesn't work on these cards. They used llama.cpp's ROCm backend for a 27B-parameter model requiring both cards.
