After literally minutes of searching and several more minutes of making the table, I bring you the following:
Let me clearly explain the 4 percentage columns. Column F is the percent above the value listed in column B, which is the core clock the card has out of the box. Column G is the same deal as Column F, only this time it is the memory speed. Column H and I are the percentages above the reference clocks for the card... which are 669/829 for the HD 3850 and 777/1,126 for the HD 3870.
