If your PC features an NVIDIA based graphics card and is using an NVIDIA display driver, you can identify the model of the GPU (Graphics Processing Unit) in your graphics card by accessing the NVIDIA System Information section of the NVIDIA Control Panel.
1) With your mouse, right-click the Windows desktop and select NVIDIA Control Panel as shown in the image below. This will launch the NVIDIA Control Panel.
2) From within the NVIDIA Control Panel, left-click the System Information link on the bottom left hand corner. This will bring up the System Information panel.
The System Information window resembles the image below. The window is divided into two panels. The left panel lists all of the NVIDIA GPUs currently installed in your PC under Items. In the example below, the notebook is powered by a Quadro 5000M GPU. The right panel lists important details about your GPU including the display driver version currently installed, the amount of video memory onboard, the video BIOS version of your GPU, etc. Scrolling down will reveal the Device ID and Part Number
Please Note: If your graphics card is inside of your PC but no drivers are installed or the drivers are not functioning correctly, you may not be able to access the NVIDIA Control Panel.
