Apple A12Z Bionic vs Apple A18

The Apple A12Z Bionic was released in 2020 and was primarily aimed at professional users in the tablet segment.

This processor is based on the A12 architecture and is manufactured using the proven 7 nm process. It features eight computing cores and an 8 MB level 2 cache, but lacks a level 3 cache. The maximum memory bandwidth is 68 GB/s. In synthetic benchmarks, the Apple A12Z Bionic shows consistent multi-core performance, but falls behind more modern solutions in single-core performance.

The integrated Apple A12Z graphics unit allows for reliable rendering in graphical applications. Since heat development remains moderate, fanless operation in slim housings is possible. The price-performance ratio is particularly interesting for price-conscious buyers looking for a stable solution for established applications.

The Apple A18 uses the Donan architecture and is manufactured in a highly efficient 3 nm process.

It is designed for modern mobile end devices where high efficiency is a priority. With a 20 MB level 2 cache and a 24 MB level 3 cache, it offers significantly optimized data processing. The memory bandwidth is specified at 60 GB/s. In direct comparison, the Apple A18 delivers significantly higher single-core and multi-core performance, with the lead clearly exceeding the ten percent mark.

For gaming, the Apple A18 (5 GPU cores) graphics unit is better suited due to its more modern structure. The low power consumption extends battery life and noticeably reduces the thermal load on the system. This processor is the right choice for users who need a future-proof and powerful solution.
