Memory

For desktop and workstation video cards, video card memory (VRAM) is used to store image data so it can be quickly accessed by the GPU. A larger VRAM capacity will allow a video card to store more texture data without having to stream it from the hard drive. For tasks such as rendering three dimensional models with textures, more VRAM allows the computer to render more quickly. Some workstation video cards can have up to 12 gigabytes of video memory while most desktop video cards usually have one to six gigabytes of video memory.

Driver Optimization

Drivers are programs that control hardware devices such as sound cards, network interface cards, and video cards. They have a direct impact on video card performance, stability, and program compatibility. Compared to drivers for desktop video cards, drivers for workstation graphics accelerators usually prioritize stability and performance for professional software applications instead of games.
