* Devices are enumerated as ``GPU.X``, where ``X={0, 1, 2,...}`` (only Intel® GPU devices are considered).
* If the system has an integrated GPU, its ``id`` is always 0 (``GPU.0``).
* The order of other GPUs is not predefined and depends on the GPU driver.
* Devices are enumerated as ``GPU.X``, where ``X={0, 1, 2,...}`` (both Intel® and non-Intel GPUs are considered).
* If the system has an integrated Intel® GPU, its ``id`` is always 0 (``GPU.0``).
* If the system does not have an integrated Intel® GPU, devices are enumerated, starting from 0.
* The order of GPUs is predefined: an integrated Intel® GPU is enumerated first, followed by discrete Intel® GPUs. The order of non-Intel® GPUs is not guaranteed.
* The ``GPU`` is an alias for ``GPU.0``.
* If the system does not have an integrated GPU, devices are enumerated, starting from 0.
* For GPUs with multi-tile architecture (multiple sub-devices in OpenCL terms), a specific tile may be addressed as ``GPU.X.Y``, where ``X,Y={0, 1, 2,...}``, ``X`` - id of the GPU device, ``Y`` - id of the tile within device ``X``

For demonstration purposes, see the :doc:`Hello Query Device C++ Sample <../../../get-started/learn-openvino/openvino-samples/hello-query-device>` that can print out the list of available devices with associated indices. Below is an example output (truncated to the device names only):
