Have you looked at the continuous testing, e.g. [0] for AMD and [1] for Intel? They consistently deliver latencies below 300 us, and for the most part, even lower. Intel largely below 50 us, AMD more around 170 us.

Remember, DAW deployments are not actual hard realtime. If you drop one chunk of samples every night, no one cares.
