That brings together the central processing unit (CPU), graphics processing unit (GPU) and other components, Bajarin explained, adding that for Apple there's also a neural processing unit (NPU) "that runs the neural engine." The primary type of chip Apple is developing is known as a system on a chip, or SoC. Within the U.S., the company has facilities in Silicon Valley, San Diego and Austin, Texas. "We built an architecture that you start with the iPhone, but then we scaled it to the iPad and then to the watch and eventually to the Mac."Īpple's silicon team has grown to thousands of engineers working across labs all over the world, including in Israel, Germany, Austria, the U.K. "We built what we call the unified memory architecture that is scalable across products," Srouji said. Two years after the acquisition, Apple launched its first custom chip, the A4, in the iPhone 4 and original iPad. With its "inherent design focus," Bajarin said, Apple wants "to control as much of the stack" as possible. Semi," said Ben Bajarin, CEO and principal analyst at Creative Strategies. "They're going to start doing their own chips: that was the immediate takeaway when they bought P.A. Semiconductor, a 150-person startup, for $278 million. A month after he joined, Apple bought P.A. Srouji came to Apple in 2008 to lead a small team of 40 or 50 engineers designing custom chips for the iPhone. "But if you look at the portfolio of chips we do: very lean, actually. "We have thousands of engineers," Srouji said. We got a rare chance to talk with the head of Apple silicon, Johny Srouji, about the company's push into the complex business of custom semiconductor development, which is also being pursued by Amazon, Google, Microsoft and Tesla. In November, CNBC visited Apple's campus in Cupertino, California, the first journalists allowed to film inside one of the company's chip labs. Meanwhile, smartphones are recovering from a deep sales slump, and competitors like Microsoft are making big leaps in artificial intelligence. Its most advanced silicon is primarily manufactured by one vendor, Taiwan Semiconductor Manufacturing Company. That change has also opened Apple up to a new set of risks. "And top of the list, of course, is our silicon." "One of the most, if not the most, profound change at Apple, certainly in our products over the last 20 years, is how we now do so many of those technologies in-house," said John Ternus, who runs hardware engineering at Apple. As of this year, all new Mac computers are powered by Apple's own silicon, ending the company's 15-plus years of reliance on Intel.
