How get GPU information in C#?

Question

I'm trying to make a software that check some information about user's Video Graphic Cards (Like: GPU Clock Speed, Bus width and etc).

I've seen this information in TechPowerUp GPU-Z software and the names of some of the SDK that you can see in the following picture:

CUDA Toolkit 7 for Nvidia and APP SDK for AMD

Now I have two questions:

1. How can I access to this information by using C# code?
2. Does CUDA Toolkit 7 and APP SDK will help to solve my problem? if it does, How?

Answer 1

Maybe the Win32_VideoController CLASS or the GPUinformation Class can help you.

Example:

using System.Management;
 
public partial class Win_Win32_VideoController : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        using (var searcher = new ManagementObjectSearcher("select * from Win32_VideoController"))
        {
            foreach (ManagementObject obj in searcher.Get())
            {
                Response.Write("Name  -  " + obj["Name"] + "</br>");
                Response.Write("DeviceID  -  " + obj["DeviceID"] + "</br>");
                Response.Write("AdapterRAM  -  " + obj["AdapterRAM"] + "</br>");
                Response.Write("AdapterDACType  -  " + obj["AdapterDACType"] + "</br>");
                Response.Write("Monochrome  -  " + obj["Monochrome"] + "</br>");
                Response.Write("InstalledDisplayDrivers  -  " + obj["InstalledDisplayDrivers"] + "</br>");
                Response.Write("DriverVersion  -  " + obj["DriverVersion"] + "</br>");
                Response.Write("VideoProcessor  -  " + obj["VideoProcessor"] + "</br>");
                Response.Write("VideoArchitecture  -  " + obj["VideoArchitecture"] + "</br>");
                Response.Write("VideoMemoryType  -  " + obj["VideoMemoryType"] + "</br>");
            }
        }
    }
}

You can also consult the CUDAfy.net library.
