[r/LocalLLaMA] Gwen3.5-27b 8 bit vs 16 bit, 10 runs

Summary

A benchmark study on Qwen3.5-27b compared the performance of 8-bit (fp8) and 16-bit (bf16) model weights and KV cache configurations using the Aider benchmark. Across 10 runs, the study found no statistically significant variance in performance between these different quantization methods. This suggests that 8-bit quantization may not significantly impact the model's performance on this benchmark, offering potential benefits for local deployment without major degradation.
