User plans $100 benchmark for Qwen3.8-27B quantizations and KV cache

A user on r/LocalLLaMA is planning a $100 benchmarking project to evaluate different quantization levels and KV cache settings for the Qwen3.8-27B model. The goal is to understand the practical trade-offs in terms of token efficiency and task performance for coding and agentic workloads, rather than just raw speed. The user intends to test various quantizations (Q6, Q5, Q4) and KV cache precisions (8-bit vs. 16-bit) on cloud GPUs, with results aimed at users with 24GB, 36GB, and 48GB of VRAM. Benchmarks will focus on coding tasks using tools like Terminal-Bench2.1 and DeepSWE, measuring not only pass rates but also token usage and context length utilization. AI

IMPACT Provides practical insights into optimizing local LLM performance for specific hardware and tasks.

RANK_REASON User-led research project evaluating model performance trade-offs. [lever_c_demoted from research: ic=1 ai=1.0]

    Planning to spend ~$100 benchmarking differnet Qwen3.8-27B quants and kv cache and looking for input before I start

    <!-- SC_OFF --><div class="md"><p>TL;DR: I'm planning to spend around $100 on cloud GPUs to benchmark Qwen3.8-27B with a focus on questions that actually matter when running it locally: different quant levels/providers, 8-bit vs 16-bit KV cache, GGUF vs EXL3, context length trade…
