The Radeon HD 6870 is a dual slot graphics card with a length of 24.8 cm (9.8"), making it slightly longer than the width of a standard ATX motherboard. Like the reference HD 5850/5870, the 6870's reference design includes a box style heatsink with a blower fan pushing air over the heatsink and out the back.

The PCB measures 24.1 cm (9.5") long but the heatsink extends past the edge by an additional 7 mm.

This is the first time we've seen side-mounted PCI-E power ports located at the side of a Radeon graphics card with a single GPU. The connectors can add about an inch to a card's effective length so moving them to the side gives it better case compatibility.

The cooler is secured with 13 screws on the trace side of the board, as well as two screws connecting it to the metal PCI bracket.

The reference cooler features a large copper base with three heatpipes surrounded by a black metal plate that provides cooling for the memory chips and voltage regulators. Taking apart the stock heatsink is a bit of a chore; the folks at Atomic Maximum Power Computing has a disassembly guide for those interested.

Unlike previous board designs, the VRMs (highlighted in red in the photo above) are located on the left side of the card. Four capacitors sit right next to them and may interfere with larger VRM heatsinks provided by third party GPU coolers.

The orientation of the mounting holes around the core is the same as previous generations. This coupled with the core being shifted toward the right to make way for the VRMs, means the 6870 is more compatible with older third party heatsinks than the 5850 and 5870.
