AMD’s Radeon RX 560X and RX 6700M are other examples of modern laptop graphics solutions that provide competitive performance to NVIDIA’s offerings. These graphics cards are designed for gaming and content creation, and they provide better performance than integrated graphics without the need for multiple graphics cards.
External Graphics Cards
Another way to add multiple graphics cards to a laptop is through external graphics cards. External graphics cards, also known as eGPUs, are designed to provide additional graphics processing power to laptops via a Thunderbolt 3 or USB-C connection.
Razer Core X and Aorus Gaming Box
The Razer Core X and Aorus Gaming Box are examples of external graphics cards that can be used with laptops. These eGPUs provide a desktop-grade graphics card experience and can be used with laptops that have a Thunderbolt 3 or USB-C connection.
Conclusion
In conclusion, while it is possible for a laptop to have multiple graphics cards, it’s not a common practice in modern laptops. Instead, laptop manufacturers have moved towards more efficient and compact graphics solutions that provide better performance without the need for multiple graphics cards. External graphics cards, on the other hand, provide a way to add additional graphics processing power to laptops, but they require a Thunderbolt 3 or USB-C connection.
| Laptop Model | Graphics Card | SLI/Crossfire |
