iPhone 18 Pro review: 2nm A20 Pro chip and better thermals

Ars Technica reviewed the iPhone 18 Pro, highlighting the new 2nm A20 Pro chip with a 6-core CPU and 7-core GPU, a larger vapor chamber for up to 40 percent better sustained performance than the iPhone 17 Pro, and a smaller Dynamic Island enabled by moving the IR camera under the OLED panel.

• A20 Pro on a 2nm node: 6-core CPU, 7-core GPU and dual 16-core Neural Engine
• Up to 40 percent better sustained performance than iPhone 17 Pro thanks to a larger vapor chamber
• IR camera moved under the OLED panel, shrinking the Dynamic Island to show up to three live activities
• New variable aperture and additional camera controls
