why laptop has 2 GPU - Intel and NVIDIA
Some laptops have 2 GPU e.g. Intel(R) HD Graphics 5500 and NVIDIA GeForce 920M. Another example is - NVIDIA GeForce MX130 and Intel(R) UHD Graphics 620.
The presence of two GPUs, e.g. the NVIDIA GeForce MX130 and the Intel UHD Graphics 620, in your laptop indicates that your laptop features switchable graphics technology. This technology is designed to provide a balance between performance and energy efficiency based on the demands of different tasks. Here's why your laptop may have these two GPUs:
1. Energy Efficiency and Performance Optimization:
Integrated Graphics (Intel UHD Graphics 620): Integrated graphics, such as the Intel UHD Graphics 620, are built directly into the CPU. They are power-efficient and ideal for handling everyday tasks like web browsing, document editing, and video playback. Integrated graphics help extend battery life and reduce heat output when performing less demanding activities.
Dedicated Graphics (NVIDIA GeForce MX130): Dedicated graphics, like the NVIDIA GeForce MX130, provide higher processing power and are optimized for graphics-intensive tasks such as gaming, video editing, and 3D rendering. They have their own dedicated video memory (VRAM) and offer superior performance for demanding applications.
2. Dynamic Switching for Optimal Performance:
Modern laptops with switchable graphics technology allow for dynamic switching between the integrated and dedicated GPUs based on workload. This ensures that your laptop can provide optimal performance and power efficiency depending on the specific tasks you're performing.
For instance:
- When you're doing basic tasks like browsing the web or working on documents, the integrated Intel UHD Graphics 620 is used to conserve power.
- When you launch a graphics-intensive application like a video game or video editing software, the system switches to the dedicated NVIDIA GeForce MX130 for better performance.
3. Heat Management and Noise Reduction:
Integrated graphics generate less heat compared to dedicated graphics. When engaged in lighter activities, using the integrated GPU helps keep your laptop cooler and quieter.
4. Cost Efficiency:
Having integrated graphics reduces the overall cost of the laptop. It makes the laptop more affordable for users who don't require a high-end dedicated graphics solution.
Using Both GPUs:
Laptop manufacturers often provide software controls that allow you to manage GPU usage. Depending on the manufacturer, you may be able to control which GPU is used for specific applications, or you can let the laptop's switchable graphics technology handle it automatically.
