Depends on the application.  Ahmdahl&#x27;s law comes into play; if there&#x27;s a non-parallelizable component to what you&#x27;re doing, it tends to dominate execution time.  Managing lots of threads isn&#x27;t really a big deal for modern operating systems, but communication between threads can be a big bottleneck.<p>Having lots of cores isn&#x27;t likely to matter much for mobile users, simply because most mobile apps are neither optimized for parallelization nor CPU-hungry in the first place.  If 4 cores are good enough, it doesn&#x27;t matter if you add hundreds more.  That said, there may be specific application that might benefit, such as computer vision.
