Apple launched new second-generation 3-nanometer chips for each the iPhone 16 and the iPhone 16 Professional fashions, bringing notable enhancements in efficiency. The iPhone 16 and 16 Plus have an A18 chip, whereas the iPhone 16 Professional and Professional Max have an A18 Professional chip.
The chips are comparable, however there are some variations to concentrate on, together with variations within the iPhone 16 and 16 Professional thermal design.
A18 and A18 Professional Shared Options
- Constructed on second-generation 3-nm course of with smaller transistors.
- 6-core CPU with 4 efficiency cores and two effectivity cores.
- Upgraded 16-core Neural Engine optimized for operating massive generative fashions.
- Upgraded reminiscence subsystem with 17 % extra reminiscence bandwidth.
A18/iPhone 16 Options
The A18 has a 5-core GPU relatively than the 6-core GPU within the A18 Professional.
The iPhone 16 fashions have a brand new thermal design. Apple says that it up to date the principle logic board, centralizing chip placement and optimizing the encompassing structure. There is a recycled aluminum substructure that dissipates warmth for 30 % larger sustained efficiency for gaming.
The A18 additionally provides {hardware} accelerated ray tracing, a characteristic that was out there within the iPhone 15 Professional fashions with A17 Professional, however is new to the usual iPhone lineup. {Hardware} accelerated ray tracing is beneficial for gaming, and the iPhone 16 fashions can run all the console-quality video games that Apple touted for the iPhone 15 Professional fashions final yr.
A18 Professional/iPhone 16 Professional Options
The A18 Professional has the identical 6-core CPU because the A18, in addition to the identical Neural Engine, nevertheless it has yet another GPU core for a 6-core GPU as a substitute of a 5-core GPU.
In line with Apple, the iPhone 16 Professional maximizes thermal capability with a machined chassis that makes use of one hundred pc recycled aluminum. It’s bonded to the titanium body utilizing strong state diffusion, and it’s mixed with a graphite clad aluminum substructure. The brand new thermal structure permits a 20 % enchancment in sustained gaming efficiency in comparison with the A17 Professional.
A18 Efficiency
In comparison with the A16 Bionic chip, the A18 Professional’s CPU is 30 % quicker, and it provides the identical efficiency whereas utilizing 30 % much less energy.
The GPU is 40 % quicker than the A16 Bionic GPU, and additionally it is extra environment friendly. It provides the identical efficiency utilizing 35% much less energy.
The brand new Neural Engine is 2x quicker for machine studying than the Neural Engine within the A16 Bionic chip.
A18 Professional Efficiency
The 6-core A18 Professional CPU is 15 % quicker than the A17 Professional CPU, and it delivers the identical efficiency utilizing 20 % much less energy. Apple says that it’s the quickest CPU in any smartphone, with next-generation ML accelerators which can be instantly programmable for high-efficiency, excessive throughput and low latency computations.
The 6-core GPU is 20 % quicker than the GPU within the A17 Professional, and {hardware} accelerated ray tracing is 2x quicker.
The upgraded Neural Engine is quicker and extra environment friendly than the Neural Engine within the A17 Professional. Apple says that Apple Intelligence options run 15 % quicker on the A18 Professional than the A17 Professional.
There’s a new superior show engine for ProMotion, a brand new video encoder, and a brand new picture sign processor. Mixed, they course of twice the quantity of knowledge for quick video encoding and improved effectivity.
