AMD announced today the ATI Mobility Radeon HD 4000 Series, a new family of discrete video cards for notebooks. The next generation of mobile graphics processors promises to bring high-definition capabilities to notebooks of all sizes, and improve on the ATI's 3000 Series performance. For thin-and-light and mainstream laptops, the ATI Mobility Radeon HD 4300 and 4500 Series pack solid graphics oomph but with a lower power pull. The platform will provide full HD 1080p video and audio support and energy efficiency for battery-life savings. The ATI Mobility Radeon HD 4600 Series is aimed at larger 15.4-inch multimedia notebooks. It delivers superior HD gaming, enhanced graphics performance, and high-definition video quality at full-HD 1080p resolution with a choice of dual-link DVI, HDMI, and DisplayPort digital outputs for maximum versatility. The ATI Mobility Radeon HD 4300, 4500 and 4600 support support audio over DisplayPort, ATI PowerExpress, switchable graphics technology and Microsoft DirectX 10.1. The upper echelon of ATI's notebook graphics is its Radeon HD 4800 series, which brings gaming and multimedia technology from the desktop to the notebook. Both the HD 4850 and 4870 provide enough graphics horsepower for extreme HD gamers, and they're the first mobile GPUs to support DDR5 memory. "The World's Most Powerful GPU," according to AMD, features dual-stream, picture-in-picture (PIP) playback capabilities, 2.8 Dual DisplayPort, and HDMI with 7.1 surround sound.
