2. Dedicated Graphics card(External graphics card) - The Dedicated Graphics card is External Graphics processing unit that is connected to the motherboard PCI-Express slot. Dedicated GPU is very powerful as compare to Integrated Graphics card. Dedicated graphics card has greater video memory(RAM). Mostly Dedicated graphics card used by the people who are working with video editing, gaming and others. Examples are GeForce RTX 3090, GeForce RTX 3060 Ti, AMD Radeon RX 6800 XT, AMD Radeon RX 5600 XT.
