XFX HD 6870 is a reference design card measuring 9.5 inches in lenght, just like the HD 5850. The cooling is also the reference solution – copper base and three heatpipes. The cooler looks like the one on HD 5850 cards, but the edges are sharper. Although both cards feature the same length PCB, HD 6870’s cooler is longer than HD 5850’s.
The I/O panel features two DisplayPort 1.2 connectors, HDMI 1.4a and two DVI connectors (one of them is single-link with maximum resolution of 1920x1200). By using a DisplayPort hub, it’s possible to chain up to three monitors to a single mini-DisplayPort. As far as sound goes, HDMI 1.4a provides Dolby TrueHD, DTS-HD, AC-3, DTS and up to 7.1 channel audio with 192KHz/24bit output.
Unlike the HD 5850, HD 6870 comes with only one CrossFire connector. This means that you can only use two cards in 2-way CrossFire.
Radeon HD 6870 consumes 151W at max so it will require two power connectors – 150W is the limit for one power connector.
