In this game it's rather more than that according to HW Unboxed. However, in many games the difference is negligible. Regardless, the new AMD cards are much faster in this game than Nvidia anyway.Please can you provide the GPU memory clocks? I will assume 2150Mhz.

Hate to break it to you but SAM/BAR is a couple of FPS difference, so I would not expect drastic changes to performance good or bad. I doubt you will even notice if its on or off.
