Apple A17 uses new 3nm architecture

The Apple A17 Pro is built on a 3nm process node, which is a step ahead of the A16 Bionic’s 4nm architecture. This smaller architecture allows for more transistors on the chip, leading to potentially higher performance. Specifically, the A17 Pro boasts 19 billion transistors compared to the A16’s 16 billion.

Benefits of the 3nm process include:

  • Power Savings: Up to 30% reduced power consumption compared to 5nm chips.
  • Performance Boost: Up to 15% increased performance for the same power consumption.

This means users of the iPhone 15 Pro and iPhone 15 Pro Max can expect longer battery life and less thermal throttling with the A17 Bionic.

The A17 Pro chip is exclusive to the iPhone 15 Pro and iPhone 15 Pro Max. In contrast, the A16 Bionic, which was first seen in the iPhone 14 Pro series, is now also powering the standard iPhone 15 and iPhone 15 Plus. This means that to experience the top-tier performance of the A17 Pro, one would need to opt for the Pro versions of the iPhone 15.

CPU Performance

  • The A17 Pro boasts a 6-core CPU configuration, an enhancement from the A16 Bionic.
  • It uses a 2 + 4 split between performance and efficiency cores.
  • The A17 Pro can reach up to 3.70 GHz, a leap from the A16 Bionic’s 3.42 GHz.
  • The new chip benefits from TSMC’s 3nm fabrication process, ensuring better performance and energy efficiency.

GPU Performance

  • The A17 Pro has an edge with 6 GPU cores, compared to the A16’s five.
  • Apple claims the A17 Pro’s GPU is 20% faster.
  • The A17 Pro introduces hardware-accelerated ray tracing, a significant upgrade from the A16’s software-based approach.
  • The Neural Engine in the A17 Pro aids in MetalFX Upscaling, enhancing graphics while conserving energy.

Memory Bandwidth

  • The A17 Pro offers more memory bandwidth than the A16 Bionic, promising enhanced graphics performance.

  • Both chips utilize LPDDR5 RAM technology.
  • It’s speculated that the A17 Pro might have an increased RAM capacity, potentially up to 8 GB.

Hardware-Accelerated Ray Tracing

  • The A17 Pro supports hardware-accelerated ray tracing, a first for Apple chips.
  • This feature was tested but not finalized for the A16 Bionic due to concerns about overheating and energy efficiency.


  • The A17 Pro houses 19 billion transistors, a jump from the A16 Bionic’s 16 billion, resulting in 10% faster performance.

Improved ISP (Image Signal Processor)

  • The A17 Pro introduces the new Photonic Engine and Smart HDR 5, ensuring better photo and video quality.
  • It also supports Mesh shading, 4K Dolby Vision HDR, Apple ProRes, Cinematic Mode, and more.


  • Both chips utilize Qualcomm’s 5G modem, but the A17 Pro upgrades to the Snapdragon X70.
  • The A17 Pro supports faster Wi-Fi 6E and a USB Controller for quicker data transfers.

Neural Engine

  • The A17 Pro’s Neural Engine is twice as fast as the A16 Bionic’s, capable of performing 35 trillion operations per second.

Dedicated Engines

  • The A17 Pro introduces three dedicated engines, including the AV1 decoder for enhanced video streaming quality.

New support for USB 3

  • The A17 Pro introduces support for USB 3, coinciding with the iPhone 15 series’ adoption of the USB-C port. This allows for transfer speeds of up to 10GB/s, which is a massive improvement, being 20 times faster than USB 2. This ensures quicker data transfers between the iPhone 15 Pro and other devices.


The iPhone 15 and iPhone 15 Pro both have beautiful 6.1-inch OLED screens that show bright colors, sharp images, and really dark blacks. This makes everything you watch look amazing.
