AMD Radeon HD 7970 Video Card Review

Media Espresso 6.5

Media Espresso is a video conversion program that uses the graphics processing unit of the video card to speed up the conversion process. We converted a 449 MB, 1920x1080i, 18,884 kbps, MPEG2 video file to a smaller 640×360, H.264, .MPG4 file for viewing on a portable device such as an iPhone or iPod Touch. We also ran this test on our two CPUs (Core i7-980X and Core i7-3960X) in order to compare the difference in performance of using a high-end CPU and a high-end GPU to transcode video.
