Here's something I posted on another thread.
I'm not certain if the formula for figuring the total benchmark score for the current RealBench has been released or if anyone has figured it out. I messed with it for some time and finally came up with how the scoring works.
((Image Editing + H.264 Rendering + Heavy Multi-Tasking) / 4) + (OpenCL/20)
Then round down to the whole number.
I'm guessing the original formula back in the days was added everything and divided by 4, but the OpenCL score was making the high variability in graphic card speed and quantity rule the day, thus the 5X devaluation of the OpenCL score.
