Intel HD Graphics is an integrated graphics card built into Intel processors (since 2010). Graphics of this type are suitable for everyday use, like multimedia playback, Internet browsing and basic work with MS Office (Word, Excel, Powerpoint).
A big advantage of Intel HD Graphics is its low energy intensity, which significantly prolongs the laptop battery life. So, if you don't plan on playing the latest games with high-demanding graphics, integrated HD Graphics will be the right choice for you.
