This 12 months Apple launched not one, however two totally new chipsets – the A18 and A18 Professional. That is additionally the primary time the vanilla iPhone fashions, the iPhone 16 and 16 Plus particularly, get a latest chipset, not a year-old one. Maybe the principle cause is to allow the high-demanding AI-related duties and options beneath the Apple Intelligence umbrella. They weren’t accessible on the A16 Bionic.
Because the names recommend, the A18 Professional powers up the iPhone 16 Professional and 16 Professional Max, whereas the non-Professional A18 is on the coronary heart of the iPhone 16 and 16 Plus. Let’s begin with the A18 Professional.
Apple A18 Professional
The A18 Professional is constructed on the 3nm manufacturing node, however that is the second-generation manufacturing course of, which is extra refined and environment friendly. The A18 Professional homes the “fastest CPU in any smartphone” and consists of 6 cores – two fundamental cores doing the heavy lifting and 4 energy-efficient cores. Put collectively, they outperform the A17 Professional’s CPU by 15% whereas utilizing 20% much less energy.

As for the GPU, it will get a desktop-class structure and might outperform its predecessor by 20% and might do ray tracing twice as quick.
The improved reminiscence bandwidth and the bigger cache dimension enable the A18 Professional get some “Advanced media” options assist. These embrace a ProMotion show supoprt, All the time-on show assist, sooner USB 3 speeds and ProRes video recording. These options are all unavailable on the common iPhones.
There’s additionally a brand new picture processing unit that improves digital camera efficiency and information processing for video encoding. That final bit is twice as quick on the A18 Professional in comparison with the A17 Professional.
In fact, the AI-related capabilities are all higher now. The NPU will get 16 cores able to 35 trillion operations per second and will get entry to 17% extra reminiscence bandwidth. It is purported to be 2x sooner and extra environment friendly than its predecessor.

The vanilla A18 chip additionally will get the brand new NPU remedy and it is largely the identical as its Professional sibling. It has a 6-core CPU with the identical setup and it is 30% sooner than final 12 months’s A16 Bionic discovered within the vanilla iPhone 15 and 15 Plus. It additionally makes use of 30% much less energy than its predecessor for a similar workloads.

The distinction lies inside the GPU and the picture processing capabilities. The non-Professional would not get the so-called “Advanced media” options, whereas the GPU will get a 5-core setup as a substitute of a 6-core setup. It is nonetheless fairly quick, although, as Apple claims 40% positive aspects in graphics efficiency over the A16 Bionic and makes use of 35% much less energy, too.
The Apple A18 chip in comparison with older generations
As per ordinary, Apple would not give away an excessive amount of details about its {hardware}, so we should wait just a little earlier than we get extra detailed specs, corresponding to CPU and GPU clock speeds, reminiscence used, and so forth.
