LTX-2.5 Brings Local Video Generation to 16GB GPUs: Mac Unified Memory vs. RTX Speed

LTX-2.5's distilled Q4_K_M model fits 15.7GB VRAM, enabling 16GB consumer GPUs to run local video generation; Macs leverage unified memory but run far slower than RTX cards; benchmarks compare LTX-2.5, H3, and Wan 2.2 across hardware, with deployment guides for ComfyUI, LTX Desktop, and MLX low-RAM mode.
