Sapphire recently announced the HD 7770 Vapor-X OC Edition, which is the first card in this generation to feature Sapphire’s exclusive implementation of Vapor chamber cooling technology. This card is based on the latest GPU technology from AMD and features 1GB of DDR5 memory. It is factory overclocked with core clocks of 1100MHz and memory clocks of 1300MHz (5.2GB/s effective) that aim to provide average performances. Working or gaming with multiple monitors is becoming increasingly popular and the Sapphire HD 7700 series supports AMD Eyefinity which is now in its second generation. The card has two DVI ports (DVI-I and DVI-D), HDMI and a single DisplayPort output, supporting up to four monitors. In addition, the cards from this series can output multiple independent audio streams allowing the correct audio content to be associated with different applications on different screens. HDMI specifications have increased in the HD 7000 series. Fast HDMI 1.4a supports Stereoscopic 3D with enhanced frame rates of 60Hz per eye - 120Hz total. It is also ready for 4K displays that can be driven from a single high-speed input of 3GHz HDMI 1.4a or DisplayPort 1.2 HBR2.
