We just recently took a look at a video card equipped with AMD's fairly new Pitcairn core, the HD 7870 from Sapphire. Today we will be looking at two more cards equipped with this Pitcairn chip: the XFX HD Double Dissipation 7870 and 7850. Both cards feature a factory overclock as well as the Double Dissipation dual fan cooler. Just as with the Sapphire HD 7870, the XFX Double Dissipation HD 7870 is equipped with 1280 stream processors, whereas the XFX Double Dissipation 7850 is only equipped with 1024 stream processors. The XFX Double Dissipation HD 7870's 28nm core comes stock clocked at 1050Mhz whereas the HD 7850 comes in at 860MHz. Hopefully we will be able to increase both of those clock speeds with a fairly decent overclock. So how will the cards stack up to the rest of the competition? Let's find out!
