Ahem i think you have misunderstood the benchmark a bit! Or radicaly rather.
If you turn to production on you disable the photon tracing and final gather wich cotributes to of the images final look!
do compare the pictures!
It not supprising you get fast results if you skip all the realy intensive calcs. Wich measure peroformance, and if the scene is not comparble then why use it!
Thet said id want to se a bechmark that doers realworld production thing ie bakes the solution and then renders a few hundred frames!
