Probably the old atom cpu. I got ~5% or less during idle on my vps server with k3s, and that's with various stuff running (nextcloud, postgres, postgis, mysql, pgadmin, phpmyadmin, wordpress, redis, memcache, several django apps + celery broker, etc). On the other hand, running kubernetes on mac immediately hog ~20% cpu, killing any hope for normal battery life.
