M5: unified memory vs VRAM tables

Bandwidth ~153.6 GB/s · memory options [16, 24, 32] GB · year 2025.

Unified memory is shared with macOS and apps. Treat discrete VRAM “fits” as overstated unless you reserve headroom. Prefer VRAM fit with a higher overhead, and compare against discrete GPUs only as a contrast—not a 1:1 map.
