Hm? Theres not really a formula as far as I remember, since each type of memory is different, GDDR2 GDDR3, GDDR4 etc, different bits, I don't believe there is a actual formula its just tested and recorded ... but I may be wrong.

There is no set formula, as there are many factors...like dual channel, GDDRx, and many more.

I told you them all... There is no formula for performance on GFX cards... You just buy one that performs well. Your never gonna find what your looking for.
