Not all quad-core CPUs are inherently superior to dual-core ones, so delineating the variances between 2-core and 4-core chips will aid you in making an informed decision when acquiring a smartphone.
The CPU is metaphorically likened to the heart of smartphones and electronic devices, entrusted with the task of processing user-defined tasks.
In contemporary times, CPUs on smartphones typically range from 2 cores upwards, with some exceptional models boasting up to 10 processing cores.
In reality, each core of a CPU is essentially a separate physical CPU. A dual-core CPU may seem similar to a single-core CPU externally, but it actually comprises 2 physical CPUs on a single chip.
The addition of a second CPU allows your computer to perform more tasks, handling multiple tasks simultaneously. For example, if you have a task, instead of one person doing the entire task from start to finish, having an extra core splits the task between two individuals, resulting in quicker execution and faster responses.
A quad-core CPU follows a similar structure, containing 4 separate physical CPUs on a single chip, providing smoother multitasking capabilities compared to a dual-core CPU.
Moreover, the cores within the same CPU also differ. For instance, if you have a quad-core CPU where 2 cores operate at high clock speeds and 2 cores operate at lower clock speeds, during basic tasks, the system will only utilize the 2 lower-speed cores to conserve energy.
However, there are also programs that are single-threaded, running only on a single processor core, so they will not take advantage of the benefits that multi-core CPUs bring.
Therefore, having a 4-core CPU does not guarantee that your machine will run faster than another smartphone with a 2-core CPU. This is because the CPU speed depends on the type of chip, the clock speed of each core, and the architectural design as well as the technologies equipped.
In general, for everyday tasks that we commonly use, a 2-core chip with high clock speed will give you a faster feeling than a 4-core chip (with lower clock speed), simply because many software programs today are still programmed to optimize for 2-core CPUs. But for heavy tasks optimized for 4 cores, a 4-core chip will be much faster than a 2-core chip, no matter how high the clock speed is (such as heavy 3D games, video editing software, or image processing).
