Benchmarking of Qwen3.6-27B shows that higher weight quantization (Q8) performs better than Q6 or Q5, even when comparing against models with unquantized KV caches. The KLD analysis indicates a widening performance gap between Q6 and Q5 quantization levels.
HOW THIS AFFECTS YOU
●
builderYou should prioritize higher weight quantization over unquantized KV if you need to maximize context within VRAM limits.
