What is the primary factor that determines the power consumption of a GPU?

  1. Clock speed

  2. Number of cores

  3. Memory bandwidth

  4. Fabrication process


Correct Option: D
Explanation:

The fabrication process, measured in nanometers (nm), determines the power efficiency of a GPU. A smaller fabrication process results in lower power consumption.

Which of these technologies is designed to reduce the power consumption of GPUs?

  1. Dynamic Voltage and Frequency Scaling (DVFS)

  2. Multi-threading

  3. Ray tracing

  4. Virtualization


Correct Option: A
Explanation:

DVFS dynamically adjusts the voltage and frequency of the GPU to reduce power consumption when the GPU is not under heavy load.

What is the term used to describe the ratio of useful work performed by a GPU to the total power consumed?

  1. Power efficiency

  2. Energy efficiency

  3. Thermal efficiency

  4. Clock efficiency


Correct Option: A
Explanation:

Power efficiency is the ratio of useful work performed by a GPU to the total power consumed, expressed in watts.

Which of these factors can contribute to increased power consumption in GPUs?

  1. Higher clock speeds

  2. More cores

  3. Larger memory capacity

  4. All of the above


Correct Option: D
Explanation:
