Video Transcoding over the GPU
A new trend in GPU development is using the GPU for things other than rendering games. Parallel processing aka Stream processing. ATI uses ATI Stream and NVIDIA uses CUDA. As the topic now slowly becomes more familiar we feel now would be a good time to start collecting data that measures the performance of the GPU while computing and crunching numbers.
One of the most definitive functions the GPU will be and can be used for, is Video Transcoding. So we sought an application that can transcode video files over both the CPU and GPU.
Below you can find the first results of this new test. In this test we transcode a 200 MB AVCHD 1920x1080i media file towards a 1280x720P MP4 binary.
So here we see the result of video transcoding. The numbers the seconds it takes to finish transcoding, the lower - the better.
As you can observe the GPU is very well suited for this process. In fact when even a 5750 utilizing ATI stream shows a tremendous performance gain as it beats a Core i7 965 with it's four CPU cores overclocked to 3.75 GHz. Think about that for a second and realize how insane that really is.
Facts, any Radeon HD series 5000 will assist the transcoding process saving time, what bugs me though is that all series 5000 cards seems to scale the same. Since this software is using both the CPU and GPU for the transcode process, the 3.75 clock Core i7 processor might be the dominating factor here.
We test and review the MSI Radeon HD 7790 OC edition, also known under SKU code R7790-1GD5-OC incl FCAT Frametimes. The new graphics card is intended to boost a little more performance into entry-level gaming.
Radeon HD 7990 review
We review the new AMD Radeon HD 7990 including FCAT frametime measurements. The dual GPU product that you guys learned to know under codename Malta finally is released. AMD it doing it in style, two fully equipped Tahiti XT2 GPUs versus good yet silent cooling. In this review we'll look at the product, the architecture, the benchmarks, including frametime based FCAT measurements. Head on over towards our AMD Radeon HD 7990.
Club3D Radeon HD 7870 Joker review
We test and review the Club3D Radeon HD 7870 Joker, this is the much discussed 7870 card that in fact has a 7900 series GPU, the Tahiti LE. For a fair amount of money this series 7800 product now offers 7900 series performance. Armed with 2GB of graphics memory it hits a sweet spot gaming performance wise and to date it one of the more popular products in the mainstream segment. Let's check out the Club3D Radeon HD 7870 Joker.
Club3D Radeon HD 7790 Crossfire review
In this article test and review the Club3D Radeon HD 7790 Crossfire incl Frametimes. If you need a little more value for money then the 13 Series R7790 might be just what you are looking for. This card is all about saving money and costs roughly 130 EUR. Have peek at our review where we'll test the 13 Series from Club3D.
