At the International CES 2009 in Las Vegas company Advanced Micro Devices (AMD) officially introduced the new family of graphics solutions ATI Mobility Radeon HD 4000, for installation of portable computers. According to the developers and their offspring in terms of productivity doubled surpass the previous generation products and enable notebooks to implement the most advanced gaming and multimedia technology, which until now were available only in desktop PCs. All new items are compatible with DirectX 10. 1 Shader Model 4. 1, supports HDMI, DisplayPort and 7. 1-channel sound, as well as equipped with the advanced hardware acceleration for decoding video ATI Avivo HD Technology with integrated videoprotsessorom second generation (Unified Video Decoder 2). In addition, through the use of 55-nm tehprotsessa and technology company such as ATI PowerPlay Technology, ATI PowerXpress Technology and ATI Switchable Graphics Technology, these graphics adapters different energy efficiency that will significantly extend the period of autonomous mobile systems based on them. In the flagship line of ATI Mobility Radeon HD 4800 Series includes new items ATI Mobility Radeon HD 4870 and ATI Mobility Radeon HD 4850 with 800 stream processors, which are targeted at computer enthusiasts, are based on 956 million transistors and staffed GDDR3 memory and GDDR5 respectively with 256-bit interface (by the way, the second type of memory used in mobile for the first time schedule). In turn, the model number of ATI Mobility Radeon HD 4600 Series includes boosters ATI Mobility Radeon HD 4670 and ATI Mobility Radeon HD 4650 with 320 stream processors, which are characterized by an optimal balance between performance and energy efficiency. These products are created from the 514 million transistors and are equipped with DDR2 or GDDR3 memory with a 128-bit bus. is noteworthy that the two aforementioned groups play well with the technology ATI CrossFireX Technology, which allows you to create a powerful configuration of a pair of video cards to better play demanding 3D-games. As for the series of ATI Mobility Radeon HD 4500 Series and ATI Mobility Radeon HD 4300 Series, they have joined, entry-level products such as ATI Mobility Radeon HD 4570, ATI Mobility Radeon HD 4530 and ATI Mobility Radeon HD 4330 , who have 80 stream processors, formed of 242 million transistors and are equipped with DDR2 or GDDR3 memory with 64-bit interface. Company AMD is confident that these solutions are ideal for notebooks average price categories, as well as ultrathin and light laptops. At last, reported that sales of the first mobile GPU family with ATI Mobility Radeon HD 4000 from the leading vendors, including ASUSTeK Computer and Micro-Star International (MSI), should start in the current quarter.
