Apple’s custom chip design has been a major driving force behind the advancements in iPhones, iPads, Apple Watches, AirPods, and Macs. Since 2010, Apple has been designing its own custom chips for iPhones, and more recently, for Macs as well. These chips, manufactured by Taiwan Semiconductor Manufacturing Company, have allowed for improvements in battery life, graphics performance, and overall efficiency across Apple’s product lineup. With a team of thousands of engineers working across chip labs worldwide, Apple’s focus on in-house chip design has inspired other tech giants like Amazon, Google, Microsoft, and Tesla to follow suit and develop their own custom chips. However, although Apple has made significant strides in chip technology, there are still areas where they rely on external suppliers, such as Qualcomm for modems and Samsung and Micron for memory. Nonetheless, Apple remains committed to becoming the largest customer at TSMC’s fab in Arizona for chip manufacturing, demonstrating their dedication to driving advancements in silicon technology.
CNBC had the exclusive opportunity to film inside an Apple chip lab and interview key figures like Johny Srouji, head of silicon at Apple, and John Ternus, senior vice president of hardware engineering. This rare insight provided valuable information about Apple’s chip development process and the challenges they face, including geopolitical risks, slowdowns, and the future of AI. With their in-house chip design, Apple believes they have a significant advantage in the AI realm, as they own the hardware, software, and machine learning components required for optimal performance. Furthermore, Apple’s transition away from using Intel processors to their own M1 chips in Macs has set a precedent for other companies to explore and invest in custom chip development. Overall, Apple’s dedication to custom chip design, optimization, and scalability has solidified its position as a leader in the industry and continues to drive advancements in their product offerings.
Apple’s Custom Chip Design
