The MacBook Air 13" M4 is a 24 GB laptop with more memory than speed: it runs 27–31B models at 5 tok/s. Among 24 GB machines, only the M5 Pro, M4 Pro and M5 write faster. macOS keeps about 3.5 GB, leaving 20.5 GB for models. Prompt reading is its weak spot: a 4K-token prompt waits 21 s before the first word on Gemma 4 26B A4B IT. At its $1,399 MSRP it gives 9.4 tok/s per $1,000, 7th of the 8 machines compared here. M4 generation, released 2025; the newer M5 writes 28% faster with 1.9× the compute.

Renting costs as much as buying after ≈3,000 hours (≈2.1 years at 4 h a day).
Each dot is a machine or GPU; hover or tap it for its numbers, click to open it. Machines without a price for the chosen basis are left out. Machines without a published power figure are left out of Per watt and costed without power. How we calculate cost per token
Other memory sizes of the same machine first, then machines and GPUs people weigh against it, each with the one reason it is worth a look. Speeds on Qwen3.5 9B.
Output speed depends on memory bandwidth (120 GB/s). Grey rows need more than the 20.5 GB available.
