The Apple A12X Bionic is a 64-bit system on a chip (SoC) designed by Apple Inc.


The Apple A12X first appeared in the 3rd-generation iPad Pro, announced on October 30, 2018. The chip is an 8-core variant of the A12 with 4 high-performance cores and 4 high-efficiency cores. Apple states that the A12X has 35 percent faster single-core CPU performance and 90 percent faster overall CPU performance than its predecessor, the Apple A10X.[1]

The design of the A12X is also used in the newer Apple A12Z.[2] According to an analysis of the processor floorplan by technology patents firm TechInsights, the A12Z is the same as the A12X chip, but with an extra GPU core enabled.[3][4] AnandTech theorized that the A12Z is a re-binned variant of the A12X, which is a common practice in semiconductor manufacturing, allowing finished units of the same design to be set to higher specifications as the quality and quantity of manufacturing yields improve over time.[5]
