How to perform smooth Activity loading using intent?

I am using navigation drawer in my app where i have a listview with few list items all are redirecting to a fragment class but i have an item which when clicked it will redirect to anactivity thus i had to use intent for that, but compared to fragment the activity intent seems lagging.

I want to know is there a way to go to an activity without using Intent or else is there any smoother way of using Intent to move from one fragment to another in the navigation drawer
