Can someone simplify this for the less educated people in terms of chips and grafic cards n all that.....please

Could be in power reference?

HD 4890 (chip RV770) = 4x (or more) the power of X360's GPU (chip R500)
HD 4670 (chip RV730) = 2x (or less) the  power of X360's GPU (chip R500)

I think your power estimations are kinda off...
