Unified Memory, Explained: Why Mini PCs Can Run 70B Models a Big GPU Can't

https://vettedconsumer.com/content/images/2026/07/minipc-card.png
Mini PCs with unified memory (e.g., AMD Strix Halo) can host large 70B LLMs due to 128GB shared memory, but generate text slowly (4-6 tok/s) due to low bandwidth (256GB/s), unlike GPUs (e.g., RTX 5090) with high bandwidth (1,792GB/s) but limited 32GB VRAM. Their strength is capacity, not speed, excelling when models exceed GPU VRAM limits despite slower inference.
