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. 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.
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. 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. It is Apple’s first SoC with an octa core CPU.
The A12X integrates an Apple-designed septa core graphics processing unit (GPU) with twice the graphics performance of the A10X. Embedded in the A12X is the M12 motion coprocessor. The A12X includes dedicated neural network hardware that Apple calls a "Next-generation Neural Engine". This neural network hardware, which is the same as found in the A12, can perform up to 5 trillion operations per second.
The A12X is manufactured by TSMC using a 7 nm FinFET process, and it contains 10 billion transistors vs. the 6.9 billion on the A12. 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.
