MVC 3 Html.RenderPartial vs Html.Partial

Question

This article states

There are some cases where you might like to step aside and write directly to the HTTP Response stream rather than having a partial view render the results (partials/views use MvcHtmlString/StringWriter)

Use Html.RenderPartial for streaming images or other elements that are media-centric or where faster download times are highly important.

What overhead does MvcHtmlString/StringWriter introduce? Are there downsides to using Html.RenderPartial all of the time, if there is less overhead?

I could not find answers on MSDN:

Answer 1

Html.RenderPartial is faster then Html.Partial because of RenderPartial give quick response to Output.

What is the difference (if any) between Html.Partial(view, model) and Html.RenderPartial(view,model) in MVC2?
