Better wheel means faster car with lower fuel costs and better handling, so yes, it absolutely makes sense. Apple employs more than hundreds of engineers just on designing the various Apple chips. They not only design the Z series used in iPhones and iPads, but also the M series, the T series, the W series, and several others. They are not 'tweaking' ARM designs. https://www.wired.com/story/apple-a13-bionic-chip-iphone/ The launch of the iPhone 11 Pro and its siblings only reaffirms that Apple's real advantage over its competitors comes from owning the entire vertical stack: the software, the system hardware, and the chip design. Apple’s decision to design and build its own silicon was made sometime in 2008. At the time, the company had a mere 40 engineers working on integrating chips from an assortment of vendors. Then, in April of 2008, Apple bought a chip startup called P.A. Semi for $287 million. That increased the total number of chip engineers to about 150 and brought home expertise on what matters most on a phone: power efficiency. Johny Srouji runs Apple's sprawling chip operation along with other hardware technologies. Many believe that a big chunk of the company’s annual research-and-development budget is earmarked for Srouji’s team. "Steve came to the conclusion that the only way for Apple to really differentiate and deliver something truly unique and truly great, you have to own your own silicon," You are wrong. Again. Still. -- The brain is an amazing organ, it works every second of every day from before we're even born right up until the instant we fall in love.
