The latest iPhone from Apple has generated a considerable amount of buzz, and much of the focus has been on the addition of USB-C. This new feature has grabbed the attention of tech enthusiasts everywhere, as it promises faster transfer speeds and improved connectivity. However, it is essential to delve deeper into the other notable aspects of the iPhone 15 Pro to ascertain its real value.
Revolutionary Graphic Enhancements
While USB-C may be stealing the show, the graphical prowess of the new iPhone should not be overlooked. Apple has incorporated ray tracing and upscaling capabilities into its flagship device, which brings it closer to the cutting-edge technology found in Nvidia GPUs. This ambitious feature set has the potential to elevate the gaming experience for PC gamers and opens doors for more immersive gameplay possibilities.
Amidst all the excitement surrounding USB-C and graphics, the most significant development lies within the iPhone 15 Pro itself – TSMC’s new 3nm silicon. This innovation holds immense significance for the future of PC gaming as it is highly likely to become the foundation for next-generation GPUs from industry giants like AMD and Nvidia.
A Rather Modest Improvement
However, a closer inspection of the A17 Pro chip, powered by TSMC’s N3 node, reveals a somewhat underwhelming performance. Compared to its predecessor, the A16 Bionic, the transistor count of the A17 Pro has seen only a modest increase, from 16 billion to 19 billion. It appears that Apple has opted for a conservative approach, possibly to control costs. Consequently, the core count remains the same, with two performance and four efficiency cores, mirroring the A16 chip.
Disappointing Performance Uplift
Perhaps the most disheartening aspect of the A17 Pro is the mere 10% improvement in CPU performance that Apple claims. This figure is quite lackluster for a brand new production node like the TSMC N3 silicon. The underwhelming performance increase encompasses both the benefits of the new silicon and Apple’s purportedly revised cores with wider decode and execution units. According to TSMC, the N3 silicon alone should offer a 10% performance boost, leading one to expect a more substantial overall improvement.
No Significant Power Efficiency Gains
Besides lackluster performance gains, one would also anticipate enhanced power efficiency from a new node like the 3nm TSMC silicon. However, Apple has not made any claims regarding improved battery life in the iPhone 15 Pro compared to its predecessor, the iPhone 14 Pro. Surprisingly, the battery life rating remains unchanged. This raises questions about the tangible benefits of the new silicon, as it fails to deliver the anticipated gains in both performance and power efficiency.
While the iPhone 15 Pro does not appear to fully leverage the potential of TSMC’s N3 node, it is essential to consider the implications for PC components, particularly GPUs from AMD and Nvidia. Unfortunately, it is difficult to determine these benefits accurately until these components hit the market. The earliest timeline for graphics cards featuring the TSMC N3 silicon is the second half of 2024. However, if the A17 Pro SoC is any indication, the prospects may not be as promising as initially believed.
While the iPhone 15 Pro generates significant hype with its adoption of USB-C and impressive graphical capabilities, there are concerns regarding the utilization of TSMC’s new 3nm silicon. The modest increase in transistor count, underwhelming performance uplift, and lack of substantial power efficiency gains offer room for skepticism. Only time will reveal the true impact of the TSMC N3 node on PC components, leaving tech enthusiasts eagerly awaiting the arrival of next-gen GPUs from AMD and Nvidia.
