Can I run Granite 4.1 8B on 8GB RAM Laptop (CPU/iGPU only)?
No. Granite 4.1 8B needs ~6.8 GB even at Q4_K_M, but 8GB RAM Laptop (CPU/iGPU only) only has ~5 GB usable.
Needs ~6.8 GB even at Q4_K_M, but only ~5 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 1.8 GB: Granite 4.1 8B needs roughly 6.8 GB at Q4_K_M and 8GB RAM Laptop (CPU/iGPU only) leaves only about 5 GB usable for a model. The lightest tracked hardware that runs Granite 4.1 8B is the Nvidia GeForce RTX 3060 (12GB) at 12 GB. See Granite 4.1 8B on Nvidia GeForce RTX 3060 (12GB).

FAQ
Can 8GB RAM Laptop (CPU/iGPU only) run Granite 4.1 8B?
No. Granite 4.1 8B needs ~6.8 GB even at Q4_K_M, but 8GB RAM Laptop (CPU/iGPU only) only has ~5 GB usable.
How much memory does Granite 4.1 8B need?
8GB RAM Laptop (CPU/iGPU only) does not have enough memory. At Q4_K_M the weights are ~5.3 GB; with KV cache and runtime overhead, budget ~6.8 GB at a 4k context.
What is the best tool to run Granite 4.1 8B on Windows?
LM Studio for a simple setup; Ollama (CUDA) for the most speed. AMD GPUs run via Vulkan/ROCm at roughly half CUDA throughput. NVIDIA is the smooth path on Windows.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
