Local AI notes

Current-gen Studio Ultra. Buy by RAM tier first (96GB+), not just chip name. New/refurb Amazon + used eBay both apply.

Mac vs discrete GPU

Unified memory helps large models load without a separate VRAM ceiling. NVIDIA usually wins tokens/sec and CUDA tooling. See Mac vs GPU for local AI.
