AMD · Vega 20 · 32 GB · Qwen3.8 27B · Q4_K_M: ~31 tok/s

AMD Radeon Instinct MI50 32GB

32 GB of HBM2 at a terabyte per second. The 32 GB version has become scarce and sells for several times the 16 GB card; passive, 300 W and retired from official ROCm support, so expect some driver archaeology, but a 32B model at Q4 runs.
