Yes, but it is tight — InternLM 3 8B Instruct at Q5_K_M needs about 7.4 GB of the 8 GB usable on RTX 4060 Laptop (8 GB VRAM, 16 GB RAM), leaving only ~0.6 GB before the runtime starts swapping. Expect ~29.6 tok/s (estimated), with room for about 16,384 tokens of context.
Q5_K_M — it needs about 7.4 GB of the 8 GB available, downloads as roughly 6.2 GB, and runs at an estimated 29.6 tokens/sec with up to 16K of context.
Nothing binding — the model fits with headroom and generates at a usable speed on this hardware.
