Bottom line

Llama 3.1 8B (~8B) is lighter than Gemma 2 9B (~9B), so it runs on more modest hardware, while Gemma 2 9B trades a larger footprint for more capacity. At 4-bit, Llama 3.1 8B needs about 6GB versus ~7GB, a meaningful gap when choosing a GPU. Llama 3.1 8B advertises the longer context window (128K vs 8K), which helps with long documents. Both can start on a NVIDIA GeForce RTX 3060 12GB-class machine. Figures are approximate working-set estimates, not benchmarks — verify the exact release before committing hardware.
