What's actually new on the iPhone 18 Pro?
A 2nm chip
The A20 Pro is Apple's first 2-nanometer chip, with a six-core CPU, a seven-core GPU, and a redesigned vapor chamber. You won't notice it in a quick speed test. You'll notice it after 20 minutes of gaming or a long video recording, when a hot phone slows down and a cooler one doesn't. Apple says the iPhone Duo's sustained performance is up to 35% better than the iPhone 17 Pro.
The first variable-aperture iPhone camera
This is the headline change. Every earlier iPhone had a fixed-aperture main lens. The iPhone 18 Pro's main camera can adjust from ƒ/1.48 to ƒ/4.0, opening wide in low light and closing down for sharper depth of field in bright conditions. The Pro controls now include manual aperture alongside shutter speed and white balance.
Smaller but useful extras
- A smaller Dynamic Island that can show up to three Live Activities
- Cinematic effects you can apply after you've shot the video, at up to 60 fps
- Siri AI, rolling out in beta with iOS 27
What hasn't changed?
Plenty. Both phones have the same 6.3" ProMotion display size, a 48MP main camera, and Face ID. If you're happy with your 17 Pro's screen, camera, and battery, you're not missing a lot in everyday use.
The price question
The iPhone 18 Pro starts at $1,199 in the US, $100 more than the iPhone 17 Pro's $1,099. The Pro Max starts at $1,299. Memory chip costs have risen sharply across the industry, and Apple has raised prices on Macs and iPads this year too. Irish euro prices differ, so check Apple's Irish website for what you'd pay here.
A $100 jump is smaller than some analysts feared, but it still adds up, especially for higher-storage models. This is why many people are weighing up whether to buy new at all.
