### Remarks

This is the PCI device ID of the user's graphics card. Together with [SystemInfo.graphicsDeviceVendorID](/engine/6000.6/script-reference/unityengine/systeminfo/graphicsdevicevendorid.md), this number uniquely identifies a particular graphics card model. The number is the same across operating systems and driver versions.

Note that device IDs are only implemented on PC (Windows/Mac/Linux) platforms and on Android when running Vulkan; on other platforms you'll have to do name-based detection if needed.

See [pci-ids.ucw.cz](http://pci-ids.ucw.cz/readPC) for a list of device IDs.
