Quad-Core processors are those processing systems that have four cores so it is capable of performing a number of tasks at the same time means it provides the power of parallel processing. These processing systems are much faster than any other processing system.
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 Quad-Core and Octa-core Processors:
| | Quad-core | Octa-core |
| 1. | 4 cores are present which can perform different tasks at the same time. | Two sets of 4 cores are present, which means a total of 8 cores that can perform numerous tasks at the same time. |
| 2. | It uses less power as compared to Octa-core hence it is power efficient. | It uses comparatively more power as compared to quad-core systems. |
| 3. | All cores work all the time. | All cores work when multiple heavy tasks are given otherwise one set is enough. |
| 4. | It generates less amount of heat. | It produces more amount of heat. |
| 5. | Single-threaded jobs can be done more efficiently. | These are designed to handle multi-threaded jobs efficiently. |
| 6. | The performance of these processors arise good. | The performance of these processors is better. |
| 7. | The power of all cores is equal. | The power of one set is high as compared to other sets of cores. |
| 8. | It can handle low and medium graphics easily. | These are made to handle complex and heavy graphics along with rendering capabilities. |
