Bottom line

Qwen2.5 1.5B (~1.5B) is lighter than Granite 3 2B (~2B), so it runs on more modest hardware, while Granite 3 2B trades a larger footprint for more capacity. At 4-bit, Qwen2.5 1.5B needs about 1GB versus ~1.6GB, a meaningful gap when choosing a GPU. Granite 3 2B advertises the longer context window (128K vs 32K), which helps with long documents. Both ship under permissive licenses, easing commercial use. 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.
