Chipset The iPhone 17 uses the Apple
A19 SoC. It incorporates the new Apple-designed
N1 networking chip, part of a trend by Apple to reduce reliance on
Broadcom and third-party chip suppliers. The
N1 supports
Wi-Fi 7,
Bluetooth 6.0, and
Thread. The iPhone 17 does not use Apple's new
C1X modem found in the iPhone Air, opting instead for
Qualcomm's
Snapdragon X80. Apple said it intends to continue adoption of its own chips going forward, but that was not the focus for this year. The iPhone 17 also removes the 128 GB storage option available on its predecessor, the
iPhone 16, making the base model iPhone the first to come only with 256 GB and 512 GB of storage, with prices starting at $799.
Display The iPhone 17 includes a larger OLED display and dynamic 120 Hz ProMotion refresh rate, marking its debut on a non-Pro iPhone model.
Security Starting with all iPhone 17 models and
iPhone Air, devices based on the
A19 and
A19 Pro include Memory Integrity Enforcement (MIE). MIE is an always-on, hardware-and-OS, memory-safety defense that uses Apple's secure memory allocators, Enhanced Memory Tagging Extension (EMTE) in synchronous mode, and Tag Confidentiality Enforcement policies. By default, MIE hardens key attack surfaces, including the
kernel and over 70 userland processes, while preserving performance. Apple states that MIE targets mercenary spyware by making end-to-end
exploit chains significantly more expensive and difficult to develop and maintain. == Reception ==
