The Card

The HIS Radeon HD 6870 is a complete implementation of the AMD reference design, which means that it uses the same PCB and cooler that all other HD 6870 cards use. The only exception here is the sticker, which is a HIS design.


AMD's reference design HD 6870 requires two slots in the system. It makes almost full use of the available height, so "breathing space" in a CrossFire configuration could be quite limited.


The card has two DVI ports, two mini-DisplayPorts and one HDMI port. AMD's display output logic is clearly superior to what NVIDIA has to offer at this time. Vendors are free to combine six TMDS links into any output configuration they want (dual-link DVI consuming two links) - and use them all at the same time. AMD has also introduced DisplayPort 1.2 support with their new cards which allows the use of a DisplayPort hub to connect multiple monitors, or daisy chain them together.

An HDMI sound device is also included in the GPU. The HDMI interface is HDMI 1.4a compatible which includes Dolby TrueHD, DTS-HD, AC-3, DTS and up to 7.1 channel audio with 192 kHz / 24-bit output. The new revision also brings support for Blu-ray 3D movies which will become important later this year when we will see first Blu-ray 3D titles shipping.


You may combine up to two HD 6850 and HD 6870 cards in CrossFire for higher performance or improved image quality settings.
