The Apple A12X Bionic is a 64-bit system on a chip (SoC) designed by Apple Inc. It first appeared in the 11-inch iPad Pro and the third-generation 12.9-inch iPad Pro, which were both announced on October 30, 2018.[3] The A12X is a variant of the A12 and Apple claims that it has 35 percent faster single-core CPU performance and 90 percent faster multi-core CPU performance than its predecessor, the A10X.[3]


The A12X features an Apple-designed 64-bit ARMv8-A octa-core CPU, with four high-performance cores called Vortex and four energy-efficient cores called Tempest.[3][1] The Vortex cores are a 7-wide decode out-of-order superscalar design, while the Tempest cores are a 3-wide decode out-of-order superscalar design. Like the Mistral cores, the Tempest cores are based on Apple's Swift cores from the Apple A6.[5] It is Apple’s first SoC with an octa core CPU.[1]

The A12X integrates an Apple-designed septa core graphics processing unit (GPU) with twice the graphics performance of the A10X.[3] Embedded in the A12X is the M12 motion coprocessor.[6] The A12X includes dedicated neural network hardware that Apple calls a "Next-generation Neural Engine".[3] This neural network hardware, which is the same as found in the A12,[1] can perform up to 5 trillion operations per second.[3]

The A12X is manufactured by TSMC using a 7 nm FinFET process, and it contains 10 billion transistors[1][3] vs. the 6.9 billion on the A12.[7] The A12X is paired with 4 GB or 6 GB of LPDDR4X memory in the third-generation 12.9" iPad Pro and the 11" iPad Pro.[8][4]
