The Apple A17 Pro is a 64-bit ARM-based system on a chip (SoC) designed by Apple Inc. and manufactured by TSMC.[5] It is used in the iPhone 15 Pro and iPhone 15 Pro Max models only[2][6] and is the first widely available SoC to be built on a 3nm process.[7][8]


The Apple A17 Pro features an Apple-designed 64-bit six-core CPU with two high-performance cores running at 3.78 GHz, and four energy-efficient cores running at 2.11 GHz.[2] Apple claims the new high-performance cores are 10% faster due to its improved branch prediction, and wider decode & execution engines, and the new energy-efficient cores are faster and 3x more efficient than the competition.[6] The amount of RAM has increased from 6 GB to 8 GB.[9]

The A17 Pro integrates a new Apple-designed six-core GPU, which Apple claims is 20% faster and their biggest redesign in the history of Apple GPUs, with added hardware accelerated ray tracing and mesh shading support. The 16-core Neural Engine is now capable of 35 trillion operations per second. The A17 Pro also added support for AV1 decoding and USB 3.2 Gen 2 (est. up to 10 Gbit/s / 1.25 GBps).[10] The A17 Pro contains 19 billion transistors, a 19% increase from the A16's transistor count of 16 billion, and is fabricated by TSMC on their 3 nm N3B process.[6]
