Summary

User reports Qwen3-Coder-Next Q4 at 40 t/s on 5 ex-mining BC-250 boards with about 71GB of VRAM exposed. Setup uses an ASRock 12-unit case with one board as the main and the rest headless, all over the boards' onboard 1Gb Ethernet. The 40 t/s figure is at 30k context and dips to around 30 t/s at 100k context. User notes the setup is wildly inefficient with power but cost less than $800, and plans to add 2 more boards to test Qwen3.8 Flash-Next.
