How to read the numbers: memory fit is calculated from real model file sizes and model configs (see assumptions). Speeds (tokens/sec) are shown only where a public benchmark exists, with a source link. Blank means "no public measurement", not "slow".
Bandwidth ceiling = memory bandwidth ÷ bytes read per generated token. It is a theoretical upper bound, not a benchmark.

Mac specs, bandwidth, US prices: apple.com Buy pages and Tech Specs, retrieved 2026-10-16. Memory-upgrade prices for Mac mini / Mac Studio come from Apple's configurator as reported by Daring Fireball (verify before buying). Where no public upgrade price was found, price is shown as "not captured".
Model sizes: actual GGUF file sizes on Hugging Face (Unsloth / bartowski repos); KV cache: computed from each model's config.json.
