AMD ATI Radeon HD 4890 Graphics Card Looks to Compete Against Nvidia

AMD's ATI Radeon HD 4890 is driven by what the chip company calls the world's most powerful processor and looks to compete against a whole new crop of graphics chips that Nvidia also officially released this week. The AMD ATI graphics card offers advantages to gamers, particularly those using the Microsoft DirectX API.

Advanced Micro Devices is rolling out a new graphics card, the ATI Radeon HD 4890, which the chip company claimed is driven by the "world's most powerful graphics processor."
Testing by GPU Review shows the HD 4890 delivers 1.36 teraflops of raw computing power, versus the 1.06 teraflops of a competing GPU. With the release of this new graphics card, AMD is looking to keep pace with Nvidia, which just released a number of new GPUs this week.
The chip is a boon to digital gamers, offering a richer visual experience as it nears the 1GH "holy grail of clock speeds." AMD works in support of Microsoft's DirectX 10 application programming interface, particularly used for game programming, and the HD 4890 card supports the latest titles for Microsoft DirectX, including Ubisoft's "Tom Clancy's H.A.W.X." and Electronic Art's "Battleforge."
The card offers an enhancement to AMD's "Dragon" desktop platform, which features its Phenom II processor, a 790 series motherboard and HD 4800 series chip, and is the successor to the Spider platform.

Research firm iSuppli recently reported that AMD showed a 1.2-percent market share loss from 2007 to 2008, but that the company was better positioned for success in 2009.

AMD recently filed documents with the SEC, after Intel accused AMD of breaching the terms of their 2001 agreement, when on March 4 AMD announced the creation of Global Foundries to handle its manufacturing needs.
