When you buy a factory overclocked card with some sort of spiffy name or a long string of capital letters denoting exactly how cool the card is, it can be disappointing to discover a 10MHz overclock on the GPU. Sapphire's Toxic HD 4890 Vapor-X
will not disappoint, it sports a 960MHz core clock speed which is 110MHz over reference and a 300MHz advantage in memory speed. That translates into a noticeable bump in frame rates and to make the card even more attractive, The Guru of 3D got even

This is kind of an odd little article over at The Inquirer: an AMD Senior Vice President, Rick Bergman, claims that they "WILL NOT engage Nvidia in a price slashing war." Uhhh, maybe I am dreaming, but I think that war is already on and in fact it was AMD that started it.

AnandTech delves into the mysterious world of graphics buffering in this article. Not anisotropic filtering as is commonly discussed; instead they are looking at the difference between double buffering plus vsync
versus triple buffering. Using a clip of a horse running you can see the speed advantage that disabling vsync while using double buffering and the penalty you pay for that gain. That same clip is used to illustrate how triple buffering can offer you the best of both worlds. Head

It would seem that AMD execs are still out for blood when it comes to the pending battle for Windows 7 and DX11 gaming. In a story posted over at the Inquirer, AMD's Rick Bergman is quoted as saying that developer support for DX11 will be much quicker than the adoption of DX10 and should come even before the end of the year.

AMDs drive to produce a new graphics driver has resulted in some lackluster updates for users. In many cases it is not worth the reboot to install the new driver and in some cases it might actually hurt your performance in specific games or CrossfireX setups. June has brought the Catalyst 9.6 to the public and again those using Radeon cards are scratching their heads wondering if they should install it or not. X-bit Labs has your answer right here, as they examine the performance im

When the NVIDIA Quadro CX professional graphics card launched in December of last year, its shining feature was the inclusion of support for video encoding acceleration on the GPU via an included piece of third-party software. In the end, I was really impressed with the inclusion of GPU computing in such a popular and usable application:

ExtremeTech is taking a close look at the two new video transcoding techniques from AMD and nVIDIA, ATI Stream and CUDA. The software transcoder they will be using comes from Cyberlink, called MediaShow Espresso, a $40 product that supports both AMD and nVIDIA's technology. The transcodes that they will attempt are for the iPhone, MPEG2, Xbox and native H.264, and they use 3 movie trailers as the media. This GPU technology certainly beats CPU encoding; but which one is the fastest?
