draginol · x · 2026-10-19

@draginol shared detailed results of running a 27B model locally on a gaming laptop. The mobile NVIDIA RTX 5080 lacks enough VRAM to fit the full model, and performance suffers as a result. Detailed benchmark data is linked in the post — a concrete example of VRAM being the main bottleneck for on-device LLM deployment.
