AMD Radeon HD 7870 GHz Edition & Radeon HD 7850 Review: Rounding Out Southern Islandsby Ryan Smith on March 5, 2012 12:01 AM EST
Our next game is Starcraft II, Blizzard’s 2010 RTS megahit. Much like Portal 2 it’s a DX9 game designed to run on a wide range of hardware so performance is quite peppy with most high-end cards, but it can still challenge a GPU when it needs to.
Once again the 7870 and 7850 place quite close to each other, particularly at 1920. Here the gap between the two is only 6%, the smallest lead the 7870 will ever have over the 7850. The good news is that this means the 7850 ties the GTX 570, however the bad news is that it means the 7870 doesn’t get much farther ahead. The 7800 series ends up looking quite good compared to the 6900 series though, with leads in the 10-15% range,
