AMD Radeon HD 7870 GHz Edition & Radeon HD 7850 Review: Rounding Out Southern Islands
by Ryan Smith on March 5, 2012 12:01 AM ESTCivilization V
Our final game, Civilization 5, gives us an interesting look at things that other RTSes cannot match, with a much weaker focus on shading in the game world, and a much greater focus on creating the geometry needed to bring such a world to life. In doing so it uses a slew of DirectX 11 technologies, including tessellation for said geometry, driver command lists for reducing CPU overhead, and compute shaders for on-the-fly texture decompression.
CivV has something interesting going on at 1920; can you spot it? For the first and only time, the 7870 ends up leading over the 7950, if only by 2%. Even though AMD’s performance improvements in CivV seem to largely be driven by compute shader performance improvements, there’s apparently still something going on with the frontend or the ROPs that makes the 7870’s higher core clockspeed matter.
In any case this is another game where the 7800 comes out looking quite good. Relative to the 6900 series there is no competition: the 7800 series is 40-50% faster. The lead against NVIDIA’s cards isn’t nearly as large, but it’s still 8% for the 7870 versus the GTX 570, and 9% for the 7850 versus the GTX 560 Ti.

Well said bro...Its like Nvidia and Amd secretly team up to maximizing profits.. AMD launch now, over price the product, Nvidia hold out for like 3-5 months, then launches a more powerful product knowing all too well that yes AMD will drop there prices, but we have the more powerful hardware so, persons will still gobble it up..
You would think with the launch of a new product line, AMD would drop the price significantly so it can encourage customer to buy off the remaining stock .

I do not think it's ok to skip hd 7970 but include nvidia 580. This makes anandtech look like it favors nvidia over amd and the entire site can be questioned.warmbit - Tuesday, April 10, 2012 - link
Here is the link to an interesting overview performance 7870 and 7850 of 5 Web sites competing Nvidia cards - GTX580 and GTX570 and penalties of the previous generation AMD - 6970 and 6950.Analysis of the results of the Radeon 7870 and 7850 in 12 games and 5 resolutions:

You will know the relationship between average interest rates these cards and you will find out in which graphics card is better in the game and resolution.
