Guide Review - Sapphire Radeon HD 4890 Vapor-X Performance 3D Graphics Card
Jun 26 2009 - Sapphire's Radeon HD 4890 Vapor-X is a drastic movement away from the ATI reference design of the 4890 series cards. Much of this comes from the unique Vapor-X cooling solution that Sapphire has put on previous cards. It is similar to the heatpipe technology used by many coolers today but in a more compact design that was originally developed for thin servers. This allows the card to run the fan at a lower speed to get the same cooling effects as a traditional graphics cooler design. The result is a dramatic reduction in fan noise.
The other major difference with the card is the connector layout. Most cards use two standard DVI connectors. Sapphire has decided to include four graphics connectors to support all the major video connectors including VGA, DVI, HDMI and DisplayPort. Even though it has four connectors, only two of them may be used at any given time. The HDMI connector also supports carrying 7.1 audio to compatible displays or receivers. Those wanting to run two DVI monitors can do so using the supplied HDMI to DVI adapter cable.
The Radeon HD 4890 graphics processors is essentially a reworked Radeon HD 4870 that allows for high base clock speeds. In the Vapor-X version, clock speeds have been bumped up to 870Mz for the core and 1050MHz for the memory from the reference 850MHz and 975MHz. In most of the 3D games today, this allows for solid frame rates at the 1920x1200 and sometimes even 2560x1600 resolutions. Some demanding game engines like Crysis will run smoothly with high detail up to 1680x1050.
One downside to the Vapor-X is its limited overclocking. The card was able to achieve roughly 100MHz extra on both core and memory clocks. Those looking for higher speeds should look at the Sapphire Toxic version for great potential but in a more reference design.
