VGA Testing Methodology
The Microsoft DirectX-11 graphics API is native to the Microsoft Windows 7 Operating System, and will be the primary O/S for our test platform. DX11 is also available as a Microsoft Update for the Windows Vista O/S, so our test results apply to both versions of the Operating System. All of the tests in this review were run with DX11 graphics.
According to the Steam hardware survey, as of December 2011 the most popular desktop resolution (for Steam users) is 1680x1050 pixels, with a 17.59% share, with 1920x1080 pixels coming in second with only 7.7%. I ran most tests at both 1680x1050 and 1920x1200 (I continue to prefer the 16:10 ratio of 1920x1200 to the mysteriously more popular 1920x1080 resolution).
I used a combination of synthetic and video game benchmark tests in this article to illustrate relative performance among graphics solutions. Our benchmark frame rate results are not intended to represent real-world graphics performance, as this experience would change based on supporting hardware and the perception of individuals playing the video game.
Note: AMD has not rolled the drivers for their new GCN video cards into their standard Catalyst release yet, so we're stuck with mysterious numbers: in this case the driver supplied with the Radeon 7770 video card is known as "ATI Driver 8.932.5-120116a-131942C-ATI".
DX11 Cost to Performance Ratio
