Intel HD Graphics integrates graphics and media processing right on the processor,
putting the two key gaming components-CPU processing and graphics-together on a single chip.
Intel HD Graphics 4000 is the enhanced graphics technology in the new 3rd generation Intel
Core processor. Intel HD Graphics 4000 delivers immersive mainstream and casual gaming capabilities.
Dedicated graphics are critical for use with programs that have intense video graphics, which many of today's games and other media do. If your video card gets overloaded, your processor will borrow memory from your PC RAM which will result in slower reaction time, especially if you are running other applications. So, the more memory you have on your video card, the less your processor will have to borrow to display graphics, which will ultimately lead to better overall performance.
