The most popular addon for boosting rendering in Blender is called the "Blender Cycles Render Engine" addon. This addon is built into Blender and can be enabled by going to the "Add-ons" section of the user preferences and selecting it from the list of available addons. It utilizes GPU rendering, which can greatly speed up rendering times compared to CPU rendering. Other addons that can boost rendering include the "Luxrender" and "Octane Render" addons.
