That chip comes with Intel® HD Graphics 3000 - which is a member of the HD Graphics Family. There should be two lines under Display Adapter in your dxdiag which state the HD Graphics type, the first one saying the family (HD Graphics Family), and the second one with your adapter string (HD Graphics 3000). Additionally, you can check the adapter string by performing the following steps;
Ctrl + Alt + F12 -> Options & Support -> Information Center -> Note the "Accelerator in use".
Right click the desktop -> Screen Resolution -> Advanced Settings -> Note the "Adapter Information".
