HIS Radeon HD 4890 Video Card

Compared to a regular ATI Radeon HD 4890, the Sapphire card clocked at 870MHz, up from 850MHz. On a regular 4890 the GDDR5 memory is clocked at 975MHz, however our 2GB card from Sapphire is clocked all the far to 1050MHz, that extremely helps in high resolution and anti-aliasing modes. Detain mind that we’re talking regarding QDR here, that makes 1050MHz an out of this world 4200MHz! Here you'll be able to see that our Sapphire Radeon HD 4890 2GB is extremely slightly longer than a Radeon HD 4870. I’d not expect the additional length to cause issues. It still works terribly simply into AN Antec 900 that is on the tiny aspect of video card area.
Something value noting is that this card needs each 6-pin and 8-pin PCI-e power cables, thanks to the extra memory and over clocking capabilities. Sapphire suggests a five hundred Watt or bigger power offer with a 6-pin PCI categorical and 8-pin PCI categorical power connexion for correct operation. If run in Crossfire they recommend a minimum of a 600W power offer with double the amount of power offer connectors.
