Leaked TSMC roadmap shows 5nm A14X Bionic is scheduled for production this year
The world’s largest contract foundry, TSMC, is starting chip production using the 5nm process mode this year. The process node relates to the number of transistors that fit in a square mm. The higher the transistor density, the more transistors inside a chip. The more transistors inside a chip, the more powerful and energy-efficient the chip is. Chips made using the 7nm process node like the A13 Bionic and the Snapdragon 865 Mobile Platform have approximately 96.5 million transistors per square mm. 5nm chips can squeeze 171.3 million transistors into a square mm.
Here is another way to look at this. The A13 Bionic SoC contains 8.5 billion transistors compared to the 15 billion inside the 5nm A14 Bionic chipset. The 5G 2020 iPhone models could very well be the first smartphones to sport a 5nm chipset. The Huawei Mate 40 series might be next, driven by Huawei’s first 5nm Kirin SoC.
Because there is no backlight, the color black is created on a mini-LCD screen the same way it is on an OLED display-by turning off the pixels in the appropriate area of the display. Since pixels that are turned off don’t draw any power from the battery, using dark mode will be able to save some battery life.
In 2021, TSMC’s 5nm roadmap includes the Qualcomm Snapdragon 875 Mobile Platform, Apple’s A15 Bionic chipset, and Huawei’s Kirin 1100 SoC. After that, TSMC starts testing production the 3nm process node. Chips produced using this technology will contain 300 million transistors per square mm or a 75% increase in transistor density. This means that Moore’s Law, the observation made by Intel co-founder Gordon Moore that says transistor density will double every other year, is slowly getting repealed.
