A user on r/LocalLLaMA conducted extensive benchmarks on the Qwen3.8 27B model, evaluating 21 different models across 9 quantization levels that fit within 16GB of VRAM. The analysis focused on Kullback-Leibler divergence (KLD) and perplexity to determine optimal quantization strategies. The findings suggest that q5_1/q5_1 quantization generally outperforms q8_0/q4_0 or q4_0/q8_0, and that using the highest possible model quantization at q4_0/q4_0 is often superior to lower quantizations at f16/f16.
