RTX 3060 Tests: GPU Memory Availability Alters LLM Inference Engine Execution
Abhishekcur · x · 2026-08-11
While running benchmarks on an RTX 3060 using sglang with the qwen3-4b model, developer Abhishek discovered that GPU memory availability directly influences how the inference engine executes the model.
By tweaking launch parameters like --mem-fraction-static 0.75, he observed that the underlying execution logic changes based on the remaining GPU memory. This highlights that memory allocation strategies are highly critical when optimizing local LLM inference.
