For those of you who are not claer abot the difference between intwegrated and dedicated graphics solution, I add a few words. The solution integrated graphixcs (eg, X4500 Intrel) does not come with dedicated video memory, it eats up your system memoory for geraphics processing and, consequently, slow path between syystem memory and graphics enngine causes a maor bottleneck when it comes to perormance. In additiion, an integrated graphics processor is less powerful than a dedicated core of computing power. On the oher hand, dedicated graphics card, typically have high speed dedicated video memory (for example, DDR3), which is connbected to the graphics processor. This eliminates the botlte neck and provides superior performance hcarts. Graphics processor on a special map, as a rule, support for High-End effects of the latest DirecttX and OpenGL API which gives realism and visual candy in recent games.
HD 4570 is a more rapid rate version of Mobiliy Radeon 4530/4330. It has a 64-bit meory interface and coomes with 512MB DDR3 vdieo memory. 512MB should be sufficienmt for most games and graphics needs, if you play in a crazy resolutions. (For rendering to increase the resoluttion, the more memoory it needs). DDR3-memory will meet the requirements for fast and prcoessing large amounts of textures, modern game demands. However, the 64-bit bus is less than 128 bit bus, that most of the main proposals map.
ATI Mobility Radeon 4570-based chip RV710, and it offers 80 stream processorrs. Mobility Radeon also provides the video technology, Avibvo HD, which providdes on-board 7.1 sond chip. Graphical solutin is also equipped with a 2-generation Unified Video Decoder, which supports the decodinmg of the bit stream H.264/MPEG-4 AVC and VC-1 streams. 4570 graphics unit capable of sovling all problems, including viddeo-decoding video HD.
