How these grades work

Grades are computed from the ratio of AMD Radeon RX 6800 XT's effective VRAM (16GB) to each model's required VRAM at its highest-quality quantization that still fits. S: comfortable headroom (1.5×+). A: smooth (1.2×+). B: tight but works (1.0×+). C: partial offload (0.8×+). D: heavy offload (0.5×+). F: cannot run.

Tokens-per-second figures are based on real community benchmarks (llama.cpp discussions, MLX, vLLM) scaled to model size. Real-world numbers vary with batch size, context length, and driver version.
