What is dual graphics, and how does it work?
Dual graphics refers to the ability of a computer system to utilize both a dedicated graphics processing unit (GPU) and integrated graphics simultaneously. This is possible in systems that have a CPU with integrated graphics, such as Intel Core processors with Iris graphics, and a separate dedicated GPU, such as an NVIDIA or AMD graphics card.
The way it works is that the system can dynamically switch between the two graphics processing units depending on the task at hand. For example, if you’re running a demanding game, the system can use the dedicated GPU for improved performance. But if you’re just browsing the web or working on a document, the system can use the integrated graphics to conserve power and reduce heat generation.
What are the benefits of using dual graphics?
One of the main benefits of using dual graphics is improved performance and efficiency. By dynamically switching between the two GPUs, the system can optimize power consumption and reduce heat generation.
