Apple A14 Bionic vs Apple A15 Bionic vs Apple A16 Bionic

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.

Apple A15 Bionic

The Apple A15 Bionic is a System on a Chip (SoC) from Apple that is found in the iPhone 13 and iPad Mini (2021) models. It was announced late 2021 and offers 6 cores divided in 2 performance cores and four power efficiency cores. The CPU performance increases only slightly compared to the A14, but GPU (in the higher end models) offers higher gains.

The chip is manufactured in 5nm and integrates 15.8 billion transistors (compared to the 11.8 of the A14).

Apple A16 Bionic

The Apple A16 Bionic is a System on a Chip (SoC) from Apple that is found in the iPhone 14 Pro (2022) models. It offers 6 cores divided in two performance cores (codename Everest, up to 3.46 GHz) and four power-efficiency cores (codename Sawtooth, up to 2.02). According to Apple, the most improvements were made to the efficiency cores and the improved memory bandwidth (+50% thanks to LPDDR5). According to the die analysis from angstronomics, the e-core cluster still has the same 4 MB L2 cache, but the p-cores now offer 16 MB L2 cache. The SLC (System Level Cache) however seems to be reduced to 24 MB.

The Neural Engine still offers 16 cores and offers an increased performance of 17 TOPS (vs. 15.8 of the A15) for AI tasks. The integrated graphics engine still offers 5 cores and benefits mostly from the higher memory bandwidth. The new display engine supports adaptive refresh rates down to 1 Hz, the new always-on display, and improved anti-aliasing (for the dynamic island animations).

The CPU performance only shows small improvements to the last generation (Apple A15 Bionic). Still, the A16 is by far the fastest mobile CPU for smartphones and leaves e.g. the Snapdragon 8+ Gen 1 easily behind (in Geekbench 5.4 single- and multi-thread tests).

The chip is manufactured on the modern 4nm process at TSMC and integrates nearly 16 billion transistors (compared to the 15.8 billion of the A15 and 11.8 of the A14). Apple emphasized on efficiency and e.g. mentioned 20% power savings for the big performance cores and class-leading efficiency of the e-cores.
