The $599 MacBook Neo is a thermal engineering disaster waiting to happen
My first thought when Apple announced the MacBook Neo today was "okay, but why not just get an older Air?" If you're thinking that too, you might be right. If you can find one.
The Neo starts at $599 with an A18 Pro processor, 8GB of memory, and 256GB storage, and ends at $699 with the same specs plus TouchID and 512GB of storage. It has two USB-C (not Thunderbolt) ports, a pretty basic-looking screen, a mechanical trackpad instead of haptic, and various other cost-saving measures. It's the cheapest new MacBook you can get now.
The new M5 MacBook Air starts at $1,099 with 16GB of memory and 512GB of much faster storage, a bigger and brighter screen, and proper Thunderbolt 4 ports. That's a $500 premium for what looks like a much better machine on paper.
But here's the problem: Apple's A18 Pro is a phone chip. It's designed for a 5-watt thermal envelope, not the sustained 15-20 watts you need for real work. I've seen this movie before.
Aris leaned back, coughing over a glass of cheap bourbon. 'I spent six years trying to solve thermal throttling on the 10nm node only for marketing to call it a feature,' he growled. 'This is just a fancy heater.'
- A18 Pro SoC: 3nm process, 6-core CPU, 5-core GPU, Neural Engine
- Memory: 8GB LPDDR5, unified with the SoC
- Storage: 256GB/512GB NVMe SSD
- Ports: 2x USB-C (USB 3.2 Gen 2, no Thunderbolt)
- Display: 13.6-inch, 2560x1664, 300 nits
- Thermal Design: Passive cooling only
The marketing lie here is that an A18 Pro can deliver sustained performance in a fanless chassis. Physics says otherwise. That chip was designed for burst workloads in a phone where the battery can throttle the CPU to preserve runtime. In a laptop, there's no battery to save - just a passive heatsink that will hit thermal saturation in minutes.
Compare this to the M5 MacBook Air's 3nm process with active cooling and 16GB of unified memory. The M5 can sustain 30+ watts indefinitely. The A18 Pro will be lucky to maintain 10 watts before throttling hard.
This isn't just about raw performance. It's about reliability. A chip running at 90°C instead of 60°C has significantly reduced lifespan. Apple's warranty won't cover thermal degradation after year two.

For Western markets, this matters. In Silicon Valley server farms or London's fintech hubs, sustained performance isn't optional - it's survival. The Neo might handle email and web browsing, but try running Docker containers or training a small ML model and watch it melt.
The $500 difference buys you proper thermal architecture, double the memory, faster storage, and ports that can drive external displays at 60Hz. That's not a premium - it's insurance.
Final Verdict: Wait. The Neo is a trap for budget-conscious buyers who don't understand thermal physics. Buy a used M1 Air instead, or save for the M5. Your future self will thank you when the Neo is in a landfill and the M5 is still going strong.
