Difference between Dual Core and Octa Core Processors
Dual-Core processors are those processing units that have two cores. A core is like a processing part that can complete a single time at a point in time so dual-core means that processing can be done at a faster rate. Dual-core processing systems allow performing more than one function at a time.
Octa-core processors are those processing systems that have eight cores which are arranged in two sets of four cores, each core can perform the work as that of a quad-core processing system. It was designed to give high performance and speed as compared to any other processing system.

Following is a table of differences between Dual-Core and Octa-core Processors:
Dual-Core |
Octa-Core |
|
1. | In dual-core processors, two cores are provided and each core is assigned a different task. | Oct core consists of eight cores arranged in two sets each containing four cores. |
2. | It has only two cores so it uses less power as compared to Octa-core. | It uses more power as compared to dual-core processors. |
3. | It is unable to perform a large number of tasks at the same time. | It can handle many jobs at the same time due to 8 cores. |
4. | Computational speed is slower as compared to octa-core processors. | It has a high computational speed as compared to dual-core processors. |
5. | This processor is not made to use heavy graphic applications. | All types of heavy graphic applications run smoothly. |
6. | It is designed to provide good performance. | The performance of octa-core processors is impeccable. |
7. | Tasks like 3D animation, gaming, VFX etc cannot be done on these processors. | Tasks like VFX, 3D, and gaming can be easily done on these processors. |
8. | Heat generation in these types of processors is less. | Heat generation in these types of processors is more. |
