Intel Core i5-8400 vs Apple A18 Pro

The Intel Core i5-8400 was introduced for the desktop market and targets users looking for a solid base for office work.

It is based on the Coffee Lake S architecture and is manufactured using the 14-nanometer process. With six cores and six threads, it provides a stable foundation. The Level 3 cache is 9 megabytes, while no Level 2 cache is present. In benchmarks such as Geekbench 6 and Cinebench 2024, it shows reliable single-core and multi-core performance.

Thanks to PCIe 3.0, it can be combined with dedicated graphics cards, which increases gaming performance compared to the integrated Intel UHD Graphics 630. The TDP of 65 watts requires active cooling. It is primarily present on the second-hand market as a cost-effective option for simple desktop systems.

The Apple A18 Pro is designed for mobile devices and uses the Donan architecture. It is manufactured in a 3-nanometer process, which enables high transistor density.

With six cores as well as 20 megabytes of Level 2 cache and 24 megabytes of Level 3 cache, it delivers high computing power with minimal energy consumption. In benchmarks, it significantly outperforms the Intel Core i5-8400 in single-core and multi-core performance. The integrated graphics unit Apple A18 Pro (6 GPU Cores) enables demanding visual displays but is tied to the mobile ecosystem.

Due to the high energy efficiency, heat generation remains low, which favors fanless operation. It is found in high-priced devices and offers market-leading performance per watt. For users who need maximum mobility and efficiency, this processor represents the superior solution.
