The upshot is that despite Intel's dominance in data center chips and the long reign of its x86 architecture chips in personal computers, its chips weren't as competitive. It has lost ground to fast-rising competitors such as Arm Ltd. and Qualcomm Corp. in mobile devices, longtime archrival Advanced Micro Devices Inc. in mainstream processors and Nvidia Corp. for gaming and machine learning. Even Apple Inc. has begun making its own processors, which are now running its latest MacBooks.
