The Apple A12X Bionic is a System on a Chip (SoC) from Apple that is found in the iPad Pro 11 and 12.5-inch from 2018. It offers 8 cores divided in four performance cores and four power efficiency cores (up from the 6 cores in the A12 of the iPhone XS). Compared to the previous A10X in the old iPad Pro models, Apple advertises up to 95% higher performance of the CPU cores.
The chip also includes a new GPU with 7 cores, the M12 Motion co-processor and a Neural Engine with 8 cores for up to 5 trillion operations per second.
With 10 billion transistors (A12 6.9 billion), the A12X Bionic is a big chip especially compared to the Snapdragon 835 (3 Billion) or a Skylake desktop quad-core Soc (1.75 Billion).
