NVIDIA Certified Associate – AI Infrastructure and Operations — Question 13

Which of the following statements is true about GPUs and CPUs?

Answer options

• A. GPUs are optimized for parallel tasks, while CPUs are optimized for serial tasks.
• B. GPUs have very low bandwidth main memory while CPUs have very high bandwidth main memory.
• C. GPUs and CPUs have the same number of cores, but GPUs have higher clock speeds.
• D. GPUs and CPUs have identical architectures and can be used interchangeably.

Correct answer: A

Explanation

The correct answer is A because GPUs are specifically built to handle multiple tasks simultaneously, making them ideal for parallel processing, while CPUs are designed for executing single tasks efficiently. Option B is incorrect as GPUs typically have higher bandwidth memory compared to CPUs. Options C and D are also false; GPUs generally have more cores but lower clock speeds than CPUs, and their architectures are fundamentally different, preventing them from being used interchangeably.
