Final answer:
In tasks that benefit from multi-threading, a 3 GHz Octa Core CPU will generally perform better than 3 GHz Quad Core and Dual Core CPUs.
Step-by-step explanation:
When comparing CPU performance, it is essential to consider not just the clock speed (GHz) but also the number of cores. Performance can vary greatly depending on the workload. For tasks that are designed to utilize multiple cores efficiently, such as video editing or 3D rendering, a CPU with more cores will likely perform better.
Given the options available:
- A: 3 GHz Quad Core CPU
- B: 3 GHz Dual Core CPU
- C: 3 GHz Octa Core CPU
The 3 GHz Octa Core CPU (C) will generally have better performance than both the Quad Core and Dual Core CPUs when it comes to multi-threaded tasks. Therefore, the correct answer is c. C.
