An octa-core processor is a type of central processing unit (CPU) that features eight independent cores. Each core can handle its own tasks, allowing for better multitasking and improved performance in applications that require significant processing power. This design helps devices run smoother and faster, especially when running multiple applications simultaneously. These processors are commonly found in smartphones, tablets, and computers. By distributing workloads across the eight cores, octa-core processors can efficiently manage demanding tasks like gaming, video editing, and running complex software, making them popular choices for high-performance devices.
