![]() This A7 is manufactured by Samsung on a high-κ metal gate (HKMG) 28 nm process and the chip includes over 1 billion transistors on a die 102 mm 2 in size. ![]() Apple A7 (APL0698) Īpple uses the APL0698 variant of the A7 chip, running at 1.3 GHz, in the iPhone 5S, iPad Mini 2, and iPad Mini 3. In order to reduce power consumption, this functionality has been moved to the new M7 motion coprocessor which appears to be a separate ARM-based microcontroller from NXP Semiconductors. In a change from the Apple A6, the A7 SoC no longer services the accelerometer, gyroscope and compass. It has been speculated that the security of the data in the Secure Enclave is enforced by ARM's TrustZone/ SecurCore technology. The A7 also includes an area called the "Secure Enclave" that stores and protects the data from the Touch ID fingerprint sensor on the iPhone 5S and iPad mini 3. The A7 includes a new image processor, a feature originally introduced in the A5, used for functionality related to the camera such as image stabilizing, color correction, and light balance. The A7 has a per-core L1 cache of 64 KB for data and 64 KB for instructions, a L2 cache of 1 MB shared by both CPU cores, and a 4 MB 元 cache that services the entire SoC. The A7 also integrates a graphics processing unit (GPU) which AnandTech believes to be a PowerVR G6430 in a four cluster configuration. It has 31 general purpose registers that are each 64-bits wide and 32 floating-point/ NEON registers that are each 128-bits wide. The 64-bit A64 instruction set in the ARMv8-A architecture doubles the number of registers of the A7 compared to the ARMv7 architecture used in A6. The A7 features an Apple-designed 64-bit 1.3 –1.4 GHz ARMv8-A dual-core CPU, called Cyclone. The latest software update for systems using this chip was iOS 12.5.7, released on January 23, 2023, as they were discontinued with the release of iOS 13 and iPadOS 13 in 2019. On March 21, 2017, the iPad mini 2 was discontinued, ending production of A7 chips. It is the first 64-bit SoC to ship in a consumer smartphone or tablet computer. Apple states that it is up to twice as fast and has up to twice the graphics power compared to its predecessor, the Apple A6. It first appeared in the iPhone 5S, which was announced on September 10, 2013, and the iPad Air and iPad Mini 2, which were both announced on October 22, 2013. The Apple A7 is a 64-bit system on a chip (SoC) designed by Apple Inc.
