How Video Cards Work
Discrete video cards can provide better performance as compared to integrated video cards. Discrete video cards are separate from the motherboard and include a specialized graphics processing unit (GPU). Because of their onboard GPU, discrete video cards don’t have to share the CPU with other programs.
Discrete video cards include memory of their own, measured in gigabytes (GB). Graphics memory is used by the GPU to accelerate graphics performance, store textures using game graphics, and make gaming, movies and other entertainment intensely realistic. High-performance graphics cards require a significant amount of graphics memory.
How to Get the Highest Performance
In Alienware PCs, two or more video cards can be linked together to boost total gaming performance. NVIDIA® video cards use a technology called Scalable Link Interface (SLI™) to enable two or more cards to work together when processing graphics data. Naturally, having two video cards working together to render graphics increases the available frame rate and provides more depth and detail. With the added horsepower of dual graphics cards, you can use higher resolution displays and enjoy high-definition (HD) gaming without sacrificing graphics performance.

- Using Tomb Raider’s built in benchmark tool, we plugged in an external display with a native resolution of 1920 x 1200 to the Alienware 14 and collected the results at High Quality as well as Ultra Quality (for fun).
- The Alienware 14 provides so much performance that even the Intel Core i5 with NVIDIA GeForce GT 750M combination is capable of producing an average of 41.4 frames per second with HIGH quality settings.
- Using our highest end configuration and using ULTRA quality settings, the Alienware 14 was capable of producing a playable average of 34.4 frames per second.
- Using Bioshock’s built in benchmark tool, we plugged in an external display with a native resolution of 1920 x 1200 to the Alienware 17 and collected the results at High Quality as well as Ultra Quality (for fun).
- Experience Bioshock Infinite at up to 97.7 frames per second using MEDIUM settings at a 1920 x 1200 resolution with our base CPU and GPU configuration.
- Using our highest end configuration and using
- ULTRA quality settings, the Alienware 17 produced an average 95.51 frames per second.
- Medium quality settings, the Alienware 17 produced an average 185.53 frames per second.
