ATI Launches 'Fastest and Most Powerful Graphics Card Available Today'

By Chris Faylor, Aug 12, 2008 8:56am PDT Hardware manufacturer ATI has launched the ATI Radeon HD 4870 X2, which it boasts as "the fastest and most powerful graphics card available today." That statement, ATI explained, is based on the card's "extreme top score of 6920" in the 3DMark Vantage v.101 benchmarking tool.

The dual-GPU card packs two HD 4800 graphic chips, said to provide "2.4 teraFLOPS of GPU power," and 2GB of GDDR5 memory. To illustrate the card's performance, ATI provided the above benchmarks, comparing the HD 4870 X2 to rival Nvidia's GTX 280.

At present, the HD 4870 X2 is only available from online system builders such as Alienware and Falcon Northwest, carrying a suggested price of $549, with the card expected to hit retailers shortly.

A pared-down version that sports 1GB of GDDR3 memory, dubbed the Radeon HD 4850 X2, is slated to hit in September for around $399, according to TechReport.
