AMD Radeon RX 570

No editorial image yet — generic vendor mark shown. Credentials in spec table below.

Cut-down RX 580 with 4 GB VRAM. Below the practical AI floor; 1-3B Q4 with offload at best. ROCm was never supported on Polaris in any production build; Vulkan via llama.cpp is the only path. Included for the 'I have one in my closet' audience — the answer is almost always 'try CPU offload first or upgrade.'
