Apple A12X Bionic vs Apple A14 Bionic

Apple A12X Bionic

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).

Apple A14 Bionic

The Apple A14 Bionic is a System on a Chip (SoC) from Apple that is found in the iPhone 12 and iPad Air (2020) models. It was announced late 2020 and offers 6 cores divided in 2 performance cores (Firestorm) and four power efficiency cores (Icestorm). Apple states that the A14 offers a 40 percent higher CPU performance than the old A12 in the iPad Air 2019. That should translate to a modest gain of around 20% compared to the Apple A13. The A14 integrates a fast 4-core-GPU and a 16-core Neural Engine that is able to reach a maximum of 11 TOPS. The memory controller supports LPDDR4X and 4 or 6 GB are directly above the chip (package on package - PoP).

The chip is manufactured in 5nm and integrates 11.8 billion transistors.
