Apple A18 Pro vs Apple A19 vs Apple A6x
Apple A18 Pro
► remove from comparison
The Apple A18 Pro is a powerful smartphone processor and formal successor to the A17 Pro. This new member of the Apple A processor series debuted in September 2024 alongside the iPhone 16 Pro and iPhone 16 Pro Max; it features 2 performance cores and 4 efficient cores along with a 35 TOPS NPU and the 6-core A18 Pro GPU.
The chip is said to be in large part based on the v9.2A ARM microarchitecture for near-Apple M4 IPC. 5G, Wi-Fi 7, Bluetooth 5.3, various satellite navigation systems and NFC are all supported here.
The more affordable A18 SoC has the same 2 P-cores and 4 E-cores running at slightly lower clock speeds along with a significantly slower graphics adapter. The Pro version of the chip also boasts USB 3.x support whereas devices powered by the A18 are limited to USB 2.0 speeds.
Performance
Its multi-thread benchmark scores leave the Dimensity 9300 as well as the Apple A17 Pro and the Apple A18 pretty far behind with at least a 10% advantage. Overall, Apple M1-like performance is to be expected in short-term workloads.
In the meantime, its single-thread performance comes dangerously close to the M3 and M4 chips despite their higher clocks speeds and slightly more advanced architectures. (The A18 Pro's performance cores can run at just slightly over 4.0 GHz, as far as we know.)
Performance drops are inevitable when under longer-term stress since there is no active cooling solution of any kind here.
Graphics
Like any modern graphics adapter, the 6-core A18 Pro GPU is RT-enabled. It delivers benchmark scores that are most comparable to the Immortalis-G720 MP12, Adreno 740 and Adreno 750; as a matter of fact, it even manages to beat the 7-core M1 GPU in many tests which is rather impressive. Any 2024 and 2025 iOS game will be happy with such an iGPU.
Power consumption
It appears the chip is able to briefly consume up to about 10 W when under high load, with average sustained power consumption figures hovering around 4 W.
The pretty modern TSMC N3E manufacturing process makes the A-series chip very power-efficient, as of late 2024.
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 A6x
► remove from comparisonThe Apple A6x is a dual-core-SoC (System on a Chip) with ARM compatible CPU cores (ARMv7s instruction set). Both can be clocked at up to 1400 MHz depending on the load. It is used in the iPad 4 and compared to the A6 in the iPhone 5, the A6x offers a faster GPU (PowerVR SGX544MP4).
The CPU-Performance of the A6x is similar to the Qualcomm Snapdragon S4 Pro MSM8960T, while the GPU is about as fast as the Adreno 320.
