The Apple A18 and Apple A18 Pro are a pair of 64-bit ARM-based system on a chip (SoC) designed by Apple Inc., part of the Apple silicon series. They are used in the iPhone 16 and iPhone 16 Pro lineups, and built on a second generation 3 nm process by TSMC. Announced on September 9th, 2024, they are the successors to the Apple A17 Pro processor.[3]

Design
editThe Apple A18 and A18 Pro feature an Apple-designed 64-bit ARMv9.2-A six-core CPU with two high-performance cores and four energy-efficient cores.
Apple claims the new A18 chip is up to 30% faster in single-core CPU performance compared to iPhone 15 with the A16 Bionic chip. All chips in the A18 series have 8 GB of RAM.[4]
The A18 integrates a new Apple-designed five-core GPU, now adding hardware accelerated ray tracing and mesh shading support to the non-Pro lineup. The A18 Pro has a six core GPU, with 2x faster hardware ray tracing. The new 16-core Neural Engine is capable of 35 trillion operations per second, with 2x faster machine learning thanks to 17% more memory bandwidth.
The A18 has a legacy USB 2.0 controller capable of only 480 Mbit/s through the USB-C port. The A18 Pro has a USB 3.2 Gen 2 controller capable of 10 Gb/s.
