Video Card Testing Methodology
Due to Microsoft DirectX-11 (DX11) being native to the Microsot Windows 7 Operating system, it has been our primary choice for our test bench for quite some time. The DX11 API is also available as a Microsoft Update for the older Windows Vista O/S, and it is native on the newer Windows 8 and Windows 8.1 Operating Systems.
By Benchmark Reviews high standards, we always try to take a bigger sample and do simple statistical procedures to obtain the most accurate results that represent how each item performs in a certain area. Each benchmark test starts with a “cache” run, followed by five recorded test runs. From those five scores, the two outliers are eliminated and the average from the remaining three is calculated and displayed as a score in the following pages.
Our combination of synthetic, video game, and compute benchmark tests has been chosen in this article to correctly represent relative performance among video cards. These benchmark results are not intended to represent real-world graphics performance, as this can change based on different system configurations, and the perception of individuals that play the video game.
