Dual-Core vs. Quad-Core — What's the Difference?

Difference Between Dual-Core and Quad-Core


Key Differences

Dual-core processors contain two independent central processing units (CPU cores). Quad-core processors, in contrast, have four individual CPU cores.
In a dual-core setup, the two cores can work simultaneously on different tasks, boosting multitasking capabilities and overall performance. On the other hand, with quad-core processors, having four cores means even more tasks can be handled concurrently, further enhancing performance and multitasking potential.
For many tasks, a quad-core might offer a noticeable improvement over a dual-core. However, dual-core and quad-core processors are just a part of the equation; factors like clock speed, architecture, and software optimization play essential roles in determining performance.
