Me and My Dell For Inspiron, G-Series, XPS, and Alienware computers

• Integrated–Often referred to as on-board video card, it is integrated on the system board. In some computers, the video card is integrated on the processor. Integrated video cards generally share the system memory (RAM) and the may also utilize the processor to perform video processing.

  An Accelerated Processing Unit (APU) is integrated on the same die as the processor and provides higher data transfer rates while reducing the power consumption.

• Discrete– Discrete video cards are installed separately on the systemboard. Discrete video cards have dedicated memory on the cardsand generally provide higher performance than integrated videocards. These cards are best suited for graphic intensive applications,high‑definition video games, and so on.
  NOTE When a discrete video card is installed on a computer that also has an integrated video card, the integrated video card is disabled by default. Use the BIOS setup program to select which card to use.

Switchable graphics allow computers equipped with both a low‑power integrated graphics chip, and a high‑power discrete graphics card to switch between either cards, depending on the load and requirements.
