Video Card Testing Methodology

XFX-Radeon-HD-7950-Double-Dissipation-Video-Card-FX-795A-TDFC

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.

In each benchmark test there is one ‘cache run’ that is conducted, followed by five recorded test runs. Results are collected at each setting with the highest and lowest results discarded. The remaining three results are averaged, and displayed in the performance charts on the following pages.

A combination of synthetic and video game benchmark tests have been used 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.

    Those warranty stickers don’t mean anything on cards with XFX lifetime warranties. One of my 7950 fans started grinding a bit and customer service just sent me a replacement fan module and said I could swap it out myself and that they allow customers to customize their cooling systems without breaking warranty on the card (even water cooling systems). XFX service reps are the best of any part manufacturer I’ve come across. And the card is a beast for the price!
