Bottom line

Mixtral 8x7B (MoE) (~47B) is lighter than Qwen2.5 72B (~72B), so it runs on more modest hardware, while Qwen2.5 72B trades a larger footprint for more capacity. At 4-bit, Mixtral 8x7B (MoE) needs about 28GB versus ~44GB, a meaningful gap when choosing a GPU. Qwen2.5 72B advertises the longer context window (128K vs 32K), which helps with long documents. Mixtral 8x7B (MoE)'s Apache-2.0 license is the more permissive of the two for commercial use. Minimum viable hardware differs: Mixtral 8x7B (MoE) starts on a NVIDIA RTX A6000, Qwen2.5 72B on a Apple Mac mini (M4 Pro). Figures are approximate working-set estimates, not benchmarks — verify the exact release before committing hardware.
