The A12X and A12Z are manufactured by TSMC using a 7 nm FinFET process, and it contains 10 billion transistors vs. This neural network hardware, which is the same as found in the A12, can perform up to 5 trillion operations per second. The A12X and A12Z include dedicated neural network hardware that Apple calls a "next-generation Neural Engine". The A12Z additionally features tuned performance controllers and a better thermal architecture compared to the A12X, which potentially allows for higher clock speeds. Embedded in the A12X and A12Z is the M12 motion coprocessor. The A12Z has an 8-core GPU, one more core than the A12X, enabling better performance in 4K video editing, rendering, and augmented reality. The A12X integrates an Apple-designed 7-core graphics processing unit (GPU), with twice the graphics performance of the A10X. It is Apple's first SoC with an octa core CPU. The Tempest cores are based on Apple's Swift cores from the Apple A6, and are similar in performance to ARM Cortex-A73 CPU cores. 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. The A12X and A12Z feature an Apple-designed 64-bit ARMv8.3-A octa-core CPU, with four high-performance cores called Vortex and four energy-efficient cores called Tempest. 2 Products that include the Apple A12X and A12Z Bionic.
