All five models feature exceptional memory bandwidth, board power and compute power as well as a number of industry-firsts. For example, the XFX Radeon HD 4870 is the first graphics card with GDDR5 memory.
The XFX Radeon HD 4870 (HD-487A-ZDFC) features 1.0 GB of DDR5 memory operating at 3600 Mhz, a 750 Mhz GPU clock and 800 stream processing units. Other key features are: TeraScale Graphics Engine, Unified Superscalar Shader Architecture, Accelerated Video Transcoding (AVT), ATI PowerPlay Technology, ATI CrossFireX support and DirectX 10.1 support.
The XFX Radeon HD 4850 (HD-485X-YDFC) features 512 MB of DDR3 memory operating at 1990 Mhz, a 625 Mhz GPU clock and 800 stream processing units.
To introduce the new GPU line, XFX selected these five models for their highly desirable gaming features, including superior scalability, state-of-the-art DirectX 10.1 graphics capabilities, optimal power performance and HDMI support. Designed for serious HD gaming, these graphics cards offer exceptional performance at a variety of price points.
Details on pricing are net yet available, however the cards should hit retailers soon. I'd expect the XFX 4870's to be in the $250-275 range and the XFX 4850 will most likely be in the $175-200 range.
Future collaborations will include over-clocked versions of these and other popular Radeon HD-powered cards. To learn more about XFX or its new lineup of Radeon HD-powered 4000 Series graphics cards, please visit www.xfxforce.com.
Expect reviews to be posted in the next day or two but for now you the previous 4850 benchmarks and reviews post will give you some idea of where these card should stand in terms of performance.
