TheApple A14 Bionic is a64-bit ARMv8.4-A[6]system on a chip (SoC) designed byApple Inc., part of theApple silicon series. It appears in theiPad Air (4th generation) andiPad (10th generation), as well asiPhone 12 Mini,iPhone 12,iPhone 12 Pro, andiPhone 12 Pro Max. Apple states that thecentral processing unit (CPU) performs up to 40% faster than theA12, while thegraphics processing unit (GPU) is up to 30% faster than the A12. It also includes a 16-core neural engine and new machine learning matrix accelerators that perform twice and ten times as fast, respectively.[7][8]
The Apple A14 Bionic features an Apple-designed 64-bit, six-core CPU, implementingARMv8[6] with two high-performance cores calledFirestorm and four energy-efficient cores calledIcestorm.[5]
The A14 integrates an Apple-designed four-core GPU with 30% faster graphics performance than the A12.[8] The A14 includesdedicated neural network hardware that Apple calls a new 16-core Neural Engine.[8] The Neural Engine can perform 11 trillion operations per second.[8] In addition to the separate Neural Engine, the A14 CPU includes second-generation machine learning matrix scalar multiplication accelerators (which Apple calls AMX blocks).[8][9] The A14 also includes a newimage processor with improved computational photography capabilities.[10]
A14 is manufactured byTSMC on their first-generation5 nm fabrication process, N5. This makes the A14 the first commercially available product to be manufactured on a5 nmprocess node.[11] The transistor count has increased to 11.8 billion, a 38.8% increase from theA13's transistor count of 8.5 billion.[12][13] According to Semianalysis, the die size of A14 processor is 88 mm2, with a transistor density of 134 million transistors per mm2.[14] It is manufactured in apackage on package (PoP) together with 4 GB ofLPDDR4X memory in the iPhone 12[1] and 6 GB of LPDDR4X memory in the iPhone 12 Pro.[1]
The A14 has video codec encoding support forHEVC andH.264. It has decoding support for HEVC, H.264,MPEG‑4 Part 2, andMotion JPEG.[15]
The A14 would be later used as the basis for theM1 series of chips, used in variousMacintosh andiPad models.
The table below shows the various SoCs based on the "Firestorm" and "Icestorm" microarchitectures.
