Apple A15 Bionic vs Apple A6
Apple A15 Bionic
► remove from comparison
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 A6
► remove from comparisonThe Apple A6 is a dual-core SoC found in the iPhone 5 with ARM compatible CPU cores. The A6 was developed by Apple and supports the extended ARMv7s instruction set. The clock rate of the CPU is between 800 to 1200 MHz depending on the CPU load. The integrated GPU is a PowerVR SGX543MP3 at 266 MHz.
