Apple A12X Bionic vs Apple A9X

The Apple A12X Bionic was introduced as a powerful processor for professional users. Manufactured using the 7 nm process, it is based on the A12 architecture.

With eight cores and a memory bandwidth of 68 GB/s, it offers a high computing capacity. In synthetic benchmarks, it significantly outperforms the comparison chip in both single-core and multi-core performance. The difference is well above the ten percent mark, which means a significantly higher speed.

The integrated Apple A12X graphics unit enables smooth rendering in demanding games. Thanks to efficient manufacturing, heat generation is low in relation to performance. This chip is recommended for users who need high performance for graphics-intensive tasks and value long-term use. The Apple A9X marked the entry into the professional tablet class and was aimed at users who wanted to work productively.

It is manufactured using the 16 nm process and uses the A9 architecture with two cores. The memory bandwidth is 51 GB/s, supplemented by a 4 MB L3 cache. Compared to the more modern model, the computing performance drops significantly in both single-core and multi-core applications. In gaming scenarios, the Apple A9X graphics unit reaches its load limits much faster.

Energy efficiency is lower due to the older feature size, which affects thermal dynamics. This processor is mainly found in devices for simple tasks like web browsing, as it reaches its capacity limits with complex software.
