AMD · Vega 20 · 16 GB · Qwen3.8 27B · Q4_K_M: does not fit

AMD Radeon Instinct MI50 16GB

The eBay bargain: 16 GB of HBM2 at a terabyte per second for less than any 16 GB GeForce. Passive, 300 W and retired from official ROCm support, so expect some driver archaeology, but a 14B model at Q6 runs quickly.
