SAPPHIRE HD 4890 2GB DDR5
Top graphics card from a series VAPOR-X, which is fitted with a unique condenser Vapor Chamber technology.The new Radeon series graphics cards are mainly characterized by a respectable number of 800 Shader processors, which even many times better than all the previously mentioned solutions.The core is clocked at a frequency of 870 MHz, 2048 megabytes ultra fast DDR5 memory on the 4200 MHz.All this gives the new Radeon incredible performance, almost triple the previous generation.Quick has 256-bit bus, along with unique DDR5 memory modules, throughput:134.4 gigabytes/s.Sapphire he placed this model unique dvouslotovým condenser Vapor Chamber technology.This is a steam chamber (The principle is similar to the heatpipe technology), which amplifies the heat away from the core to the heatsink ribs.Unlike tubes heatpipe offers even better efficiency, and especially a much larger area.
Unlike competing products is used the most advanced 55 nm manufacturing process, through which the card is very efficient even at maximum load.Supported, of course, all the latest technologies including DirectX 101, OpenGL 2nd1, involvement of multiple graphics cards in CrossFire mode or fast transfer of video Avivo.The card is also equipped with an integrated video processor UDV 2nd0, which reduces the CPU when playing HD video.The involvement of the computer is a modern PCI Express x16 interface, version 20 with double bandwidth.Among the advantages are certainly cards now 4 different types of outputs for monitor or TV - DVI, DisplayPort, HDMI and the older D-Sub.
