MediaTek Dimensity 9400 vs Apple A19

The MediaTek Dimensity 9400 is a state-of-the-art mobile processor for flagship smartphones from MediaTek; the Apple A19 is a very advanced mobile processor from Apple, exclusive to their premium mobile devices.

Both CPUs are manufactured using the 3 nm process. The Dimensity 9400 uses Cortex-X5, -X4, and -A725 cores, with 0 MB L2/L3 cache and 77 GB/s memory bandwidth. The A19 features a custom core architecture, 6 MB L2 cache, 0 MB L3 cache, and 68 GB/s memory bandwidth. In single-core operation, the Apple A19 shows significantly higher performance.

For multi-core applications, both processors are in a comparable performance range, with the Dimensity 9400 having slightly higher, but marginal, overall performance. The Dimensity 9400 features an ARM Immortalis-G925 MC12 graphics unit, while the A19 integrates an Apple A19 graphics unit (5 GPU cores).

Both offer very good gaming performance thanks to advanced integrated graphics units. The 3 nm processors are designed for high energy efficiency for mobile devices. Power consumption and TDP vary depending on the load; exact values are rarely publicly specified. These processors are not available separately in retail but are integral components of end devices.

The price-performance ratio is tied to the overall price of the smartphones; Apple products are typically in the premium segment. In summary, the MediaTek Dimensity 9400 offers strong multi-core performance and high memory bandwidth, suitable for demanding applications. The Apple A19 impresses with superior single-core performance and exceptional responsiveness for a seamless user experience.
