Apple A19 vs Apple A19 Pro
Apple A19
► remove from comparison
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.
Apple A19 Pro

The Apple A19 Pro (codenamed Thera) 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 16 MB L2 cache and four efficiency cores with up to 2.6 GHz and 6 MB L2 cache. Together, the CPU cores can access the 32 MB system level cache (SLC). L2 and SLC cache size is the main difference to the cheaper Apple A19.
The integrated GPU can offer 5 cores (iPhone Air) or all 6 cores (iPhone 17 Pro) depending on the model and clocks with up to 1620 MHz (via @faridofanani96).
The integrated AI unit called Neural Engine still offers 16 cores, but with improved memory bandwidth according to Apple. Furthermore, the engine can work together with the new AI units in the GPU.
The integrated LPDDR5X memory controller in the iPhones supports 12 GB LPDDR5X-9600 (resp. 8533 in the Air) with up to 75.8 GB/s memory bandwidth.
The CPU performance is improved compared to the Apple A18 Pro by approx. 15% (single core) or 20% (multi-core) and thanks to the new vapor-chamber cooling in the iPhones, sustained performance in particular has been improved.
The chip is manufactured in the modern N3P process at TSMC.
