The core is also clocked lower, the Radeon HD 4830 is clocked at 575MHz while the 4850 has a 625MHz GPU. Compared to the Radeon HD 4850, computing power dropped from 1 teraFLOPS to 740 gigaFLOPS and memory bandwidth dropped from 64GB/s to 57.6GB/s. Despite the lower performance, the maximum board power remains at 110W.
“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 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.
