The official site of Sapphire Technology picture soon emerged of two very original versions of performance graphics adapter ATI Radeon HD 4870, each of which is equipped newest dvuhslotovym cooler Vapor-X, the first time in the international exhibition CeBIT 2009 in Hanover. Models Sapphire Radeon HD 4870 1GB GDDR5 Vapor-X Cooling and Sapphire Radeon HD 4870 2GB GDDR5 Vapor-X Cooling differ only available on board memory GDDR5 256-bit interface, which in the first case is 1 GB, while the second is already 2 GB. This system is used for lowering the temperature of the main hotspots of both decisions, organically combines the method of the active air-cooling technology to the evaporator chamber (Vapor Chamber Technology). It`s no secret that the latter has already been successfully adapted the developers to some of the original series Accelerators TOXIC, but this time the creators have decided to discontinue the use of heat pipes, as it was before. Direct contact with the surface videochipa same vaporization chamber and its base is adjacent aluminum radiator with radially arranged ribs bifurcate at the ends. In turn, the radiator has a big enough fan, while the entire top structure covered attractive plastic casing with blue LED lighting effect in one of the parties. In addition, the diversion of excess heat from the power of food chains with the special aluminum radiator with a very large size. New items on the printed circuit board formed a non-standard blue, based on produced by 55-nm chip technology RV770 XT with 800 stream processors and constructed under the bus PCI Express 2. 0 x16. Video cards compatible with DirectX 10. 1 Shader Model 4. 1 and supporting technologies such as ATI CrossFireX Multi-GPU Technology, ATI PowerPlay and ATI Avivo HD Technology with an integrated video processor second-generation (Unified Video Decoder 2).
