Currently, the development of mobile phone processors has reached a stage where further improvements are becoming increasingly challenging. While ARM Cortex-A53 and Cortex-A57 are not new architectures, they remain widely used in the market. In the absence of significant architectural innovation, boosting performance often comes at the cost of higher power consumption. Beyond process technology upgrades, it's hard to imagine any other way to achieve major improvements in mobile SoCs in a short period.
Kim Ki-nam, President of Samsung Semiconductor, recently announced that Samsung's 14nm FinFET process is progressing well and that customers have already started mass production. However, the identity of this "customer" remains unclear. The most likely candidate is Apple, as the S1 chip in the Apple Watch is currently facing power efficiency challenges. It makes sense for Apple to adopt the new 14nm process. Additionally, the A9 chip in the upcoming iPhone next year may also be manufactured on this advanced node. Another possibility is Qualcomm, given its foundry agreement with Samsung.
Samsung claims that its 14nm FinFET process offers a 20% performance boost over TSMC’s 20nm, reduces power consumption by 35%, and shrinks the footprint by 15%. This represents a comprehensive improvement. However, TSMC’s 16nm FinFET process is still strong and continues to dominate the market. With the mobile SoC industry expected to see a major process upgrade in the coming years, both companies are set to compete fiercely in the next phase of semiconductor advancement.
Samsung's 14nm FinFET process has now entered mass production, marking a significant step forward in semiconductor manufacturing capabilities.
