JAKARTA - Apple is expected to bring major changes to the next iPhone Pro line through the iPhone 18 Pro and iPhone 18 Pro Max by adopting the A20 Pro chip based on a 2 nanometer (2nm) manufacturing process. If realized, this step will not only bring performance and power efficiency improvements, but also potentially increase production costs and limit the availability of devices during the initial launch period.

Until now, Apple has not officially announced the iPhone 18 Pro, including specifications, design, price, and launch schedule. However, various supply chain reports indicate that the latest generation of iPhone Pro will be one of Apple's first products to utilize TSMC's 2nm manufacturing technology.

Unlike the iPhone 17 Pro which is built on a relatively mature 3nm manufacturing platform, the iPhone 18 Pro is expected to enter a more complex phase of technological transition. The transition includes the use of a new transistor architecture, limited wafer production capacity, and challenges in maintaining the level of production success or yield.

In the previous generation, Apple focused more on improving sustainable performance, battery efficiency, cooling systems, and device design. The iPhone 17 Pro is also said to rely on a vapor chamber cooling system to help maintain processor performance when running games, video processing, artificial intelligence (AI) on the device, and using the camera for a long time.

Meanwhile, the iPhone 18 Pro is rumored to combine a new manufacturing process with a number of other design changes, including on the screen and physical control system. The combination is considered to make the development and production process more challenging than the previous generation.

In the semiconductor industry, the term 2nm no longer refers to the physical size of the transistor, but rather becomes a marker of the manufacturing technology generation. One of the main changes in TSMC's N2 process is the use of a nanosheet gate-all-around (GAA) transistor architecture that replaces the FinFET design.

The technology allows for better control of electric current so that it can increase the efficiency of transistor work as well as reduce power leakage. For smart phone processors, this improvement can be used to deliver higher performance at the same power consumption or maintain similar performance with lower power consumption.

That flexibility allows Apple to allocate improvements to the chip's capabilities to various aspects, such as increased CPU and GPU speeds, better battery efficiency, Neural Engine capacity for AI features, larger caches, and even more thermal space before performance drops due to heat.

However, this advantage is also accompanied by higher costs. The design, validation, fabrication, packaging, and testing processes of the new generation chips are becoming more complex and expensive.

The center of attention on the iPhone 18 Pro is expected to be on the A20 Pro chip. Various reports say Apple will use TSMC's 2nm technology for its premium processor, although the company has not confirmed the name of the chip or the manufacturing process to be used.

TSMC previously said that N2 technology has the potential to offer performance improvements of around 10 to 15 percent at the same power consumption or a power consumption reduction of around 25 to 30 percent at the equivalent performance level compared to the previous 3nm generation. However, these figures are manufacturing technology targets and not guarantees of final performance in commercial devices.

Actual performance will depend on various factors, including CPU and GPU design, cache capacity, memory bandwidth, AI accelerator capabilities, modem integration, device cooling system, power management by iOS, to the level of chip production success in the early stages.

Therefore, the biggest improvement of the A20 Pro is not necessarily only seen from the benchmark score, but also from the ability to maintain high performance for longer with lower temperatures and more efficient power consumption.

Another challenge that is considered crucial is the level of production success or yield. In semiconductor manufacturing, one silicon wafer contains many chips. The number of chips that can be used depends on the level of production defects, chip size, success of packaging processes, test results, and quality selection processes.

If the yield in the early stage is still low, the number of chips that can be used from each wafer will be reduced so that the production cost per chip increases. This condition is a concern considering Apple produces the iPhone Pro line in tens of millions of units.

Minor disruptions in the production process can affect the number of devices available at launch, distribution to various countries, storage capacity configuration, and component allocation.

Reports that the price of 2nm wafers reaches around 30,000 US dollars still need to be treated with caution because the actual price depends on the agreement between chip manufacturers and customers. However, various parties estimate that the cost of producing 2nm wafers will indeed be higher than previous generations of manufacturing.

In addition to chip fabrication, packaging technology is also expected to be an important factor. Various rumors associate the A20 Pro with the use of wafer-level multi-chip module techniques that allow components to be integrated more closely to improve performance while saving space.

However, this approach also presents new challenges in heat distribution, high-speed signal integrity, alignment tolerance during assembly, test complexity, and component failure analysis.

For Apple, the decision on packaging technology not only affects processor performance, but also the size of the logic board, the space available for the battery, the placement of the camera module, as well as the heat dissipation path to the device frame. With these various challenges, the success of the commercialization of 2nm technology is expected to be one of the main factors that determine the launch of the iPhone 18 Pro.
