What GPU does the Intel N3700 have?

You have integrated graphics, which means there's no discrete graphics card in your computer, but instead the CPU serves as a graphics card, using your system RAM rather than dedicated RAM on a graphics card.

If you wish to see the version of your integrated graphics, go to Device Manager, expand Display Adapters, right click on Intel(R) HD Graphics Family, and hit Properties. In the Drivers tab, you should find the version of your graphics driver for your display.

For more information, see Graphics Specifications on your processor's page on Intel's website.
