cification The SAPPHIRE HD 4890 Vapor-X model is a new SAPPHIRE original design. It has SAPPHIRE’s Vapor-X cooling module on the GPU together with a heatsink and profiled fan venting heat out of the case. It is quieter with core clock speed of 850MHz and 1GB of DDR5 memory clocked at 975MHz. Any two of the four output options can be used simultaneously, giving maximum flexibility for connection to different display types. An HDMI to DVI adaptor is also included for those who wish to use a pair of DVI monitors. Vapor-X Cooling Vapor Chamber Technology is based on the same principles as heatpipe technology. A liquid coolant is vaporised at a hot surface, the resulting vapor is condensed at a cold surface then the liquid is returned to the hot surface. The recirculation process is controlled by a patented wick system. SAPPHIRE Vapor-X flattens the whole system into a slim chamber - which in the graphics application is mounted in contact with the surface of the graphics chip.
