Can I run Gemma 2 27B on 8GB RAM Laptop (CPU/iGPU only)?
No. Gemma 2 27B needs ~18.7 GB even at Q4_K_M, but 8GB RAM Laptop (CPU/iGPU only) only has ~5 GB usable.
Needs ~18.7 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 13.7 GB: Gemma 2 27B needs roughly 18.7 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 Gemma 2 27B is the Nvidia GeForce RTX 4090 (24GB) at 24 GB. See Gemma 2 27B on Nvidia GeForce RTX 4090 (24GB).

FAQ
Can 8GB RAM Laptop (CPU/iGPU only) run Gemma 2 27B?
No. Gemma 2 27B needs ~18.7 GB even at Q4_K_M, but 8GB RAM Laptop (CPU/iGPU only) only has ~5 GB usable.
How much memory does Gemma 2 27B need?
8GB RAM Laptop (CPU/iGPU only) does not have enough memory. At Q4_K_M the weights are ~16.65 GB; with KV cache and runtime overhead, budget ~18.7 GB at a 4k context.
What is the best tool to run Gemma 2 27B 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.
