AMD Radeon HD 6870 and 6850 review

AMD's Radeon HD 6850

Here's the reference Radeon HD 6850, as supplied by AMD. Note the complete lack of ATI branding? You may well have seen this before; AMD sanctioned pictures to be posted on Tuesday morning.

Looking rather spiffy in a black-and-red livery, the Radeon HD 6850 1,024MB measures in at 9in and uses a dual-slot cooler.

A single CrossFire connector informs you it's a 6-series mid-range card.

1,024MB of GDDR5 memory is housed on the top-side. AMD has opted to run with the low-power variant, clocked in at a conservative 4GHz.

And here are the chips: eight 1Gb devices surrounding the Barts Pro GPU.

The large heatsink uses a radial fan to push air across the GPU and memory and out of the card. Some air may escape through the vents on the side, though.

A single PCIe connector means that folks with relatively low-powered PSUs will be able to run this beast. We'd recommend a 400W supply as a minimum.

Connectors ahoy. Counting 'em up, dual-link DVI; single-link DVI, HDMI; mini-DisplayPort, and a second mini-DisplayPort. Note you cannot use the two DVI and HDMI to drive three screens.
