Apple A12X Bionic vs Apple A15 Bionic (5-GPU)

The Apple A12X Bionic, introduced in 2018, was designed for iPad Pro models. The Apple A15 Bionic (5-GPU), released in 2021, is found in current iPhone and iPad Mini generations.

The Apple A12X Bionic (A12 architecture) is manufactured using the 7 nm process, featuring an 8-core CPU (four performance, four efficiency cores) and a 7-core GPU (Apple A12X), as well as 8 MB of L2 cache. The Apple A15 Bionic (5-GPU) (A15 architecture) utilizes the more advanced 5 nm process and offers a 6-core CPU (two performance, four efficiency cores), a 5-core GPU (Apple A15 (5 GPU Cores)), 16 MB of L2, and 32 MB of L3 cache.

In single-core and multi-core performance, the Apple A15 Bionic (5-GPU) significantly surpasses the Apple A12X Bionic. The newer chip shows superior performance due to its more advanced architecture and higher clock speeds; differences exceed 10 percent. For gaming, the Apple A15 Bionic (5-GPU) offers significantly better performance.

This is due to its newer, more efficient GPU architecture and the large 32 MB L3 cache, which is an advantage over the older 7-core GPU of the Apple A12X Bionic. Thanks to its 5 nm manufacturing process, the Apple A15 Bionic (5-GPU) is considerably more energy-efficient than the Apple A12X Bionic, which is produced using the 7 nm process.

This results in better performance per watt. The price-performance evaluation of both processors is tied to the respective integrated devices. The Apple A12X Bionic continues to offer solid performance in older devices. The Apple A15 Bionic (5-GPU) represents current top performance in newer devices.

In summary, the Apple A12X Bionic is recommended for basic tasks and cost-efficiency. The Apple A15 Bionic (5-GPU) is the choice for demanding applications, intensive gaming, and users seeking future-proof technology with superior performance and energy efficiency.
