XFX HD 6790 Review (dual fan)

XFX box artwork is always brilliant, and this one is a subtle, and slightly futuristic play on the dual fan configuration of the card.

Inside, the bundle is spartan, with no power or video converters. There is plenty of literature on XFX products including their power supply range. There is also a ‘Do Not Disturb' sign for a door handle.

The XFX HD6790 is built around a custom, black PCB design, with a modified heatpipe cooler incorporated. We have used similar dual fan heatpipe coolers from XFX before, and they are exceptionally good. We have high hopes this particular model will be just as impressive.

The HD6790 is CrossfireX capable, only in dual configurations. You need to aim into a higher range if you want 3, or even 4 way CrossfireX.

The HD6790 requires two 6 pin PCI E power connectors to operate. The last generation HD5770 only needed one.

The XFX HD6790 board follows the AMD reference design, with two mini DisplayPort connectors, HDMI and dual DVI output configuration. The Sapphire card we looked at recently opted for full sized connectors.

This particular board uses a tri-heat pipe, direct contact cooling method. The heatpipes are very nicely engineered and they split the heat transfer up into two rows of aluminum fins.

The card uses quality Hynix H5GQ1H24afr memory.

An overview of the hardware in GPUz. This is a reference clocked card operating at 840mhz core, and 1050mhz (4200mhz effective) from the 1GB of GDDR5 memory. This is connected via a 256 bit memory interface.
