History
PredecessorApple A14

The Apple A15 Bionic is a 64-bit ARM-based system on a chip (SoC) designed by Apple Inc. It is used in the iPhone 13 and 13 Mini, iPhone 13 Pro and 13 Pro Max, iPad Mini (6th generation) and iPhone SE (3rd generation).[4]

Design[]

The Apple A15 Bionic features an Apple-designed 64-bit six-core CPU implementing ARMv8 with two high-performance cores called Avalanche and four energy-efficient cores called Blizzard. Apple claims the A15 in the iPhones is 50% faster than the competition. Apple claims the A15 in the iPad Mini 6 is 40% faster than the A12.[5] An in-depth breakdown by Anandtech revealed that "compared to the A14, the new A15 increases the peak single-core frequency of the two-performance core cluster by 8%, now reaching up to 3240MHz compared to the 2998MHz of the previous generation. When both performance cores are active, their operating frequency goes up by 10%, both now running at 3180MHz compared to the previous generation’s 2890MHz".[6][7]

The A15 contains 15 billion transistors and includes dedicated neural network hardware that Apple calls a new 16-core Neural Engine.[8] The Neural Engine can perform 15.8 trillion operations per second, faster than A14's 11 trillion operations per second (+ 43%).[8] The A15 also includes a new image processor (ISP) with improved computational photography capabilities.[9] Apple also boosted performance by doubling the system cache to 32MB.[10]

The A15 has video codec encoding support for HEVC and H.264. It has decoding support for HEVC, H.264, MPEG‑4 Part 2, and Motion JPEG.[11] Codecs VP8 and VP9 are also unofficially supported. The AV1 codec is not supported via hardware acceleration.[12]

A15 is manufactured by TSMC, reportedly on their second-generation 5 nm fabrication process, N5P.[13][14]

GPU[]

The A15 integrates an Apple-designed five-core GPU for the iPad mini 6, iPhone 13 Pro and Pro Max models, while one GPU core is disabled in the iPhone SE (3rd generation), iPhone 13, and 13 Mini, resulting in a four-core GPU for these models.[15] Apple claims the A15's five-core GPU is 50% faster than the competition. Apple claims the A15's four-core GPU is 30% faster than the competition.[5]
