What is the advantage of having multiple cores on a CPU?

• A. It allows higher clock speeds.
• B. It reduces the CPU power consumption dramatically.
• C. Each CPU core processes data independently so more cores means more instructions can be carried out at once.
• D. It eliminates the need for a cache.

Answer: (C)

The advantage comes from parallel execution across multiple cores. Each core has its own pipeline and resources, so when a workload can run in parallel, the operating system can distribute different threads to different cores and they execute at the same time. This increases the total amount of work done per unit of time, which is why tasks like rendering, video encoding, or compiling large programs finish faster as you add more cores. The clock speed of each core isn’t automatically higher just because you have more cores, so simply adding cores doesn’t guarantee higher frequency. Power usage and cache design also matter, and the idea of eliminating caches isn’t realistic, since caches remain essential for keeping cores fed with data.
