Maybe its like HD4870 - back when they didn't have all the error checking and correction features working yet.

Or perhaps nVidia is having similar GDDR5 "training" growing pains.

Besides, AMD invented it and thus used it longer. Why would you expect nVidia to become GDDR5-guru overnight?

On the flip side though, GTX480 is at least 6 months newer than HD5870. nVidia may have sourced some Samsung 6Gb or even 7Gb chips.

300GB/s is a nice round number, dont you think?
