The Apple A19 (codenamed Tilos) is a smartphone chip from Apple that was launched in 2025. It integrates 6 CPU cores divided into two performance cores with up to 4.26 GHz and 8 MB L2 cache and four efficiency cores with up to 2.6 GHz and 4 MB L2 cache. Together, the CPU cores can access the 12 MB system level cache (SLC). L2 and SLC cache size is the main difference to the more expensive Apple A19 Pro.
The integrated GPU offers 5 cores with up to 1620 MHz (via @faridofanani96).
The AI engine is called Neural Engine still offers 16 cores, but according to Apple with improved memory bandwidth. Furthermore, the engine can work together with the new AI units in the GPU.
The integrated LPDDR5X memory controller in the iPhones supports 8 GB LPDDR5X-8533 with up to 68.26 GB/s memory bandwidth.
The CPU performance is only slightly lower than the A19 Pro (due to the smaller caches) and therefore still faster than last year's A18 Pro.
The chip is manufactured in the modern N3P process at TSMC.
