Everyone who knows anything about Flash and HTML5 knows that in terms of CPU resources HTML5 is still far far far FAR behind on what the Flash plugin can do... yes, even now.
I don't think those benchmark links are really furthering your argument; in both Chrome and Safari on my Mac I get roughly twice the FPS with the HTML5 version...
