Apple's $599 MacBook Neo runs an A18 Pro chip, the same silicon found in the iPhone 16 Pro, not a dedicated Mac chip. The M5 MacBook Air costs $1,099 and that $500 gap buys you real differences: the M5 starts with 16GB unified memory versus the Neo's 8GB, runs Thunderbolt ports instead of standard USB-C, supports Wi-Fi 7 versus Wi-Fi 6E, and ships with a slightly larger 13.6-inch display at higher brightness.
The port situation is the sharpest hidden trade-off. The Neo's USB-C ports are slower for data transfer and cannot drive external displays with the same flexibility as Thunderbolt. Battery life, build quality, camera hardware, and speaker systems also favor the Air. The Neo is not a bad machine, it is a constrained one, and this video maps exactly where Apple drew each line.
The argument worth reading in full is the chip framing: using A18 Pro instead of M-series silicon is a deliberate architectural choice that affects not just benchmarks but the entire software and accessory ecosystem going forward. If you are deciding between these two, the $500 question is really about whether 8GB, slower ports, and an iPhone chip are acceptable for your workload, or whether they will cost you more in workarounds than the price difference itself.
