Why may you ask do I use the 6870s instead of the common 7950s well its simple for around 900w total Power Usage (tested from the wall at full load) I can run at 2.1Kh/s. Sapphire 6870s use a Cypress GPU which is better than most of the Barts 6870s and allow it to get much better results for the power and are also 1/3 the price.
That explains the kh/s rates. Someone just slapped a 6870 sticker on it, even though it is just a 5870. (Rebranded)
Can anyone actually find any info on these "cards". I can't find any info about them on the sapphire site (all of their 6870s use the Barts like they should).
The only thing that pops up for me is something on techpowerup that says these were supposedly released this year. (Sapphire HD 6870 1600SP Edition)
Well now I feel better. Actually was starting to think someone knew of some magic way to make a 6870 get that many kh/s.
Just smoke and mirrors. haha.
