$80 PS5-chip mining boards repurposed for AI inference; dev claims $22K monthly revenue

A Chinese developer is claiming to run an AI inference service on "AMD BC-250" mining boards — built around PlayStation 5-derived APUs and selling for about $80 each — generating roughly $22,000 in monthly revenue. The claim spread as an example of a low-cost alternative at a time when startups reportedly face waitlists of up to eight months for NVIDIA's H100.
