has officially announced its HD 6870 card and it looks like it will be available in two versions, the R6870 Twin Frozr II and the R6870 Twin Frozr II/OC.
Both cards are pretty much the same as they come with 1GB of GDDR5 memory paired up with a 256-bit memory interface. The cards feature overvoltage function for the GPU via MSI's Afterburner utility, "Military Class components" and MSI's own Twin Frozr II cooler. The cooler comes with two 80mm fans paired up with a rather large heatsink and five SuperPipe heatpipes. According to MSI, this is enough to make the card 19°C cooler and 12.8dB quieter when compared to reference cooled cards.
According to the official specs over at MSI's website, the OC version works at 920MHz for the GPU and 4200MHz for the memory while the plain, non-OC version ended up clocked at 900/4200MHz.
Unfortunately, these cards are yet to show up in retail/e-tail so we are not sure about the price difference, but non-OC sound pretty good considering the fact that it will most likely be able to achieve OC clocks.
