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.
