IIRC Intel's OpenCL CPU implementation supports out-of-order queues; I
don't know about their iGPUs. Intel surely knows (they have an OpenCL
Take care when testing: AFAIK there is no guarantee that the execution
order (including parallel execution of commands) is identical across
runs -> if a test "passes" this may mean extremely little in general.
