A20 Pro moves flagship smartphone chips into the 2nm era

Apple's A20 Pro is now the first 2nm smartphone processor reaching consumers through the iPhone 18 Pro generation. The chip combines a six-core CPU, seven-core GPU and dual 16-core neural engines, with Apple claiming significant improvements in CPU speed, graphics performance and memory bandwidth. Manufacturing improvements alone do not guarantee better real-world performance, but lower-power operation is particularly valuable on phones because thermal constraints quickly limit sustained workloads.

Apple has paired A20 Pro with larger vapour chambers to keep gaming and AI workloads running at high speeds for longer. The chip also powers the upcoming iPhone Duo, which must drive two displays and more complex multitasking. MediaTek is preparing its own 2nm flagship announcement for September 15, meaning Apple's technical lead will immediately face competition.

Smartphone silicon is entering a phase where efficiency, AI acceleration and neural graphics techniques matter as much as traditional benchmark performance.
