Not just AI, Apple’s new A18, A18 Pro SoC brings massive performance gains to the iPhone 16 series

At its September 9 ‘It’s Glowtime’ event, Apple unveiled its latest iPhone models, including the iPhone 16, iPhone 16 Plus, iPhone 16 Pro, and iPhone 16 Pro Max, each powered by the newly introduced A18 and A18 Pro chipsets.

These new chips are poised to deliver significant performance enhancements, marking a considerable leap forward from the previous generation.

The first smartphone with 3nm SoCs
One of the most notable advancements in the A18 and A18 Pro chipsets is their 3nm technology, making them the first smartphone chips to employ this cutting-edge process. The term “nanometers” refers to the size of individual transistors on a chip.

Smaller transistors allow more to be packed onto a single chip, increasing efficiency and performance. While the real-world benefits of 3nm technology will be assessed through detailed testing, Apple’s implementation represents a significant milestone.

This development is expected to prompt other manufacturers to adopt 3nm technology shortly, potentially setting new standards in smartphone performance.

A18 Chip: Enhanced Efficiency and Power
The A18 chip is featured in the iPhone 16 and iPhone 16 Plus. It includes a 6-core CPU, a 5-core GPU, and a 16-core Neural Engine designed to handle large generative models and advanced machine-learning tasks. The CPU is divided into two performance cores and four efficiency cores.

Apple claims that this configuration provides a 30 percent increase in performance compared to the A16 Bionic chip found in the iPhone 15 and iPhone 15 Plus. Notably, the A18 is also said to achieve this performance boost while using 30 percent less power, making it more efficient overall.

In terms of graphics, the A18’s GPU is reported to deliver a 40 percent improvement in performance over its predecessor. This GPU supports hardware-accelerated ray tracing, a technology that simulates realistic lighting effects, enhancing the visual quality of modern games. Apple asserts that the GPU maintains its superior performance while consuming 35 percent less power, which could lead to longer battery life and more efficient operation.

Additionally, the A18 chipset features a 17 per cent increase in memory bandwidth compared to the A16 Bionic. Memory bandwidth refers to the amount of data that can be processed at once, and this increase should improve overall system performance, although Apple has not disclosed specific figures.

A18 Pro Chip: Advanced Features for Pro Models
The A18 Pro chipset, found in the iPhone 16 Pro and iPhone 16 Pro Max, builds on the advancements of the A18 but with a few notable enhancements. Although the A18 Pro offers more modest improvements than the A17 Pro, which was already a high-performing chip, it still brings significant upgrades.

The A18 Pro also features a 6-core CPU, split into two performance and four efficiency cores. Apple claims a 15 percent increase in performance over the A17 Pro while using 20 percent less power. This improvement underscores the chip’s efficiency and ability to handle demanding tasks with reduced energy consumption.

The A18 Pro’s GPU, which includes an additional core compared to the A18, is reported to provide a 20 percent boost in performance. Apple showcased the A18 Pro’s capabilities with the game Death Stranding, illustrating its ability to handle high-end graphics and complex gaming environments. The A18 Pro also includes a 16-core neural engine, similar to the A18, but with enhancements that Apple describes as “next-generation machine learning accelerators” to improve AI performance.

Furthermore, the A18 Pro chipset features enhanced memory bandwidth, matching the 17 percent increase in the A18. This improvement facilitates better data handling and overall system efficiency. For professional users, the A18 Pro offers doubled video encoding speeds and faster USB 3 data transfer rates, although specific details about these features were not fully disclosed during the event.

As the iPhone 16 series begins to roll out with these new chipsets, the performance gains offered by the A18 and A18 Pro are anticipated to set new benchmarks for smartphone technology. With advancements in processing power, energy efficiency, and graphics performance, Apple’s latest chips are poised to deliver a significant leap in user experience, paving the way for future innovations in the smartphone industry.
