An octa-core processor is a type of central processing unit (CPU) that has eight individual cores. Each core can handle its own tasks, allowing the processor to perform multiple operations simultaneously. This design improves the overall performance and efficiency of devices, especially when running demanding applications or multitasking. These processors are commonly found in smartphones, tablets, and computers. By distributing workloads across the eight cores, an octa-core processor can provide faster processing speeds and better energy management compared to processors with fewer cores. This makes them ideal for gaming, video editing, and other resource-intensive activities.
