The Apple A7 is a

iPad Air and iPad Mini 2, which were both announced on October 22, 2013. 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.[10] It is the first 64-bit SoC to ship in a consumer smartphone or tablet computer.[11] On March 21, 2017, the iPad mini 2 was discontinued, ending production of A7 chips. 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.

Design

The A7 features an Apple-designed

NEON registers that are each 128-bits wide.[7]

The A7 also integrates a graphics processing unit (GPU) which AnandTech believes to be a PowerVR G6430 in a four cluster configuration.[9]

The A7 has a per-core

MB shared by both CPU cores,[6] and a 4 MB L3 cache that services the entire SoC.[5]

The A7 includes a new

M7 motion coprocessor[16][17] which appears to be a separate ARM-based microcontroller from NXP Semiconductors.[18]

Apple A7 (APL0698)

Apple uses the APL0698 variant of the A7 chip, running at 1.3 GHz,

LPDDR3 DRAM with a 64-bit wide memory interface onto the package.[6][23]

Apple A7 (APL5698)

Apple uses the APL5698 variant of the A7 chip, running at 1.4 GHz,

iPad Air. Its die is identical in size and layout to that of the first A7 and is manufactured by Samsung.[24] However, unlike the first version of the A7, the A7 used in the iPad Air is not on a PoP, having no stacked RAM. Instead it uses a chip-on-board mounting, immediately adjacent DRAM, and is covered by a metallic heat spreader, similar to the Apple A5X and A6X.[24][25]

Patent litigation

The A7's

University of Wisconsin. On July 24, 2017, Apple was ordered to pay WARF $506 million for patent infringement. Apple filed an appellate brief on October 26, 2017, with the U.S. Court of Appeals for the Federal Circuit, that argued that Apple did not infringe on the patent owned by the Wisconsin Alumni Research Foundation.[28] On September 28, 2018, the ruling was overturned on appeal and the award thrown out by the U.S. Federal Circuit Court of Appeals.[29] The patent expired in December 2016.[30]
