+# Intel GPU is integrated or discrete #
+
+A new device descriptor will be added which will provide information if Intel GPU is integrated or discrete.
+
+
+## Version ##
+
+The extension supports this query in version 9 and later.

+## Device Information Descriptors ##
+
+| Device Descriptors | Return Type | Description |

+## Aspects ##
+
+A new aspect, ext\_intel\_gpu\_is\_integrated, will be added.
+
+
+## Error Condition ##
+
+Throws a synchronous `exception` with the `errc::feature_not_supported` error code if the device does not have `aspect::ext_intel_gpu_is_integrated`.
+
+## Example Usage ##
+
+Then the information about if GPU is integrated or discrete can be obtained using the standard get\_info() interface.

 # Maximum Memory Bandwidth #
 
 A new device descriptor will be added which will provide the maximum memory bandwidth.  If the device is a subdevice, then the maximum bandwidth of the subdevice is returned.
