the best hardware for real dash

what is the best board to install real dash on it, has less than 10 sec to boot , for project gauge cluster with 12.3 inches screen , any recommendation.

From a completely powered off state, there might not be many SBCs that can do under 10 seconds. From a suspend/sleep state 10 seconds can easily be done.

can you mention some of these boards

I’m currently using a mele quieter2 running Linux.
