Apple A12 Bionic vs Apple A15 Bionic (4-GPU)

Last updated:
The Apple A12 Bionic, introduced in 2018, was a leading processor for smartphones and tablets like the iPhone XS.

The Apple A15 Bionic (4-GPU), introduced in 2021, is a newer generation for models like the iPhone 13 series, designed for higher performance requirements.

The A12 Bionic is manufactured using a 7 nm process (Hexa-Core, 8 MB L2 cache). The A15 Bionic (4-GPU) uses a more advanced 5 nm process (Hexa-Core, 16 MB L2 and 32 MB L3 cache). Both offer a maximum memory bandwidth of 34 GB/s. The A15 Bionic (4-GPU) significantly outperforms the A12 Bionic in single-core and multi-core performance, leading to noticeably faster applications and more efficient multitasking.

For gaming, the A15 Bionic (4-GPU) is clearly superior. Its integrated graphics unit (Apple A15 with 4 GPU Cores) offers significantly higher performance than the Apple A12 graphics, enabling smoother frame rates and higher detail. The 5 nm A15 Bionic (4-GPU) is more energy-efficient than the 7 nm A12 Bionic.

This often results in longer battery life with the same or higher power density. A12 Bionic devices are cheaper on the used market today and offer good value for money for everyday tasks. A15 Bionic (4-GPU) devices are more expensive but offer higher performance and more modern features. A12 Bionic: cost-effective for standard tasks.

A15 Bionic (4-GPU): higher CPU/GPU performance, improved energy efficiency, ideal for demanding applications and gaming. For maximum speed, the A15 Bionic (4-GPU) is the better choice.
