HARDWARE PROFILE CONTEXT

How to read the hardware profiles

Intro

Local AI hardware guidance starts with memory. System RAM, GPU VRAM, and Mac unified memory are different constraints. This directory gives conservative planning profiles rather than tested benchmark claims.

Hardware groups

Group	Profiles
RAM tiers	8GB laptop, 16GB laptop, 32GB laptop, 64GB workstation
Mac unified memory	8GB, 16GB, 32GB Apple Silicon profiles
Windows GPU	NVIDIA 8GB, 12GB, 16GB, 24GB profiles
Low-power machines	mini PC and integrated graphics profiles

Evidence caveat

Hardware profiles are planning records unless marked tested. They should link to the RAM/VRAM calculator and the main 8GB/16GB/32GB articles.
