SUNNYVALE, Calif. — 10/23/2008 — AMD (NYSE: AMD) today introduced the ATI Radeon™ HD 4830 graphics card, raising the performance bar for graphics cards priced at less than $150 (USD)1 and presenting gamers with even more affordable access to award-winning ATI Radeon™ HD 4800 series performance. Like all ATI Radeon™ HD 4800 series products, the new offering delivers class-leading game performance1 and superior HD multimedia capabilities, as well support for the latest DirectX® 10.1 games soon to be released for the holiday season.

“The ATI Radeon HD 4830 graphics card is another example of how AMD’s scalable design strategy is paying off,” said Rick Bergman, senior vice president and general manager, Graphics Products Group, AMD. “With a single chip we have been able to quickly and efficiently bring to market graphics card designs ranging from below $150 through $549 SEP, with leading performance in every segment. The ATI Radeon HD 4830 continues that great trend, providing tremendous value to gamers for less than $150.”

“The $100-$150 graphics card price band represents the ‘sweet spot’ of the desktop PC graphics market where the consumer gets the most graphics performance per dollar spent,” said Dean McCarron, founder and principal, Mercury Research. “This is where the latest graphics technologies reach the mainstream PC audience, and this is the level that most PC games target.”

Resetting the performance bar below $150
The ATI Radeon™ HD 4830 graphics card delivers outstanding value to gamers. With the launch of this card, even the most intimidating games that were previously unplayable on a graphics card selling for less than $150 can now be enjoyed at playable frame rates, even when using image enhancements such as anti-aliasing and anisotropic filtering.2 For those gamers looking to get even more performance out of their gaming rigs, ATI Radeon™ HD 4830 cards support ATI CrossFireX™ technology allowing gamers to combine as many as four cards in one PC.3

Phenomenal HD multimedia experience
More than just a gaming card, the ATI Radeon HD 4830 offers up exceptional HD multimedia performance as well. All ATI Radeon HD 4800 series cards allow users to enjoy HD digital content4 with uncompromising visual fidelity while helping to enhance the definition and clarity of lower resolution visual media. AMD’s second generation Unified Video Decoder (UVD 2.0) ensures users experience smooth HD video playback, and sharp, crisp images and vibrant colors through ATI Avivo™ HD technology. Combined with capabilities like picture-in-picture, and support for the latest HD audio technologies like 7.1 surround sound, the ATI Radeon HD 4830 graphics card serves up an impressive cinema-quality home entertainment experience.

Ecosystem support
The ATI Radeon HD 4830 graphics card is supported by a dozen add-in-board companies offering custom designs of the products. Partners include ASUS, Club 3D, Diamond Multimedia, Force3D, GECUBE, GIGABYTE, HIS (Hightech Information Systems), Jetway, MSI, Palit Multimedia, PowerColor, SAPPHIRE Technology and VisionTek.
