The more cores, the faster they can deliver the request you’re asking the device to do. That means multiple cores like Octa core devices make your experience a lot faster, no waiting because time is money: Apps load quickly. You can capture high-quality photos or HD video and then browse through your collection without pause. Animations and videos play smoothly without stuttering. Games don’t get bogged down. There are exceptions, but generally, the more cores the better the performance.
