XFX HD7770 Black Edition S Crossfire & HD7750 DD Review

The latest XFX artwork all focuses on the ‘DD' logo, covered in ice. Its effective.

The bundle contains a ‘Do Not Disturb' door sign and literature on XFX products, such as their power supplies. They bundle a software disc with drivers. It is always best checking the AMD support site for updated drivers however.

The XFX HD7750 DD is built around a matt black PCB, which is very attractive. The cooler is the new silver and black metal design with twin fans in the middle. These fans are smaller than the units on the more expensive, high end cards.

The HD7750 has an HDMI and Displayport, alongside two DVI ports. XFX use a custom backplate with their logo cut into it. It is Eyefinity capable.

The cooler really looks good from all angles, with the product name highlighted on the red strip from the rear side. The HD7750 DD is Crossfire capable, in a two way configuration. It doesn't require a power connector, taking all the power it needs from the socket.

More ‘void if removed' stickers on the cooler mounting screws. Be aware that if you remove the cooler to apply your own thermal paste that the warranty is no longer valid. I really do not feel this is a necessary precaution by XFX, no other card manufacturer does it. Power supplies? sure I can understand that.

I always apply my own thermal paste on a new video card, but maybe I am in the minority.

There really is no need for their cooler to have multiple heatpipes, as it won't produce much heat. The cooler has a copper base and several generous racks of aluminum fins on either side. This XFX board is using Hynix H5GQ2H24MFR memory, same as the other boards we have looked at.

Above, the tiny cooler HIS used on their HD7750, so as you can see XFX really have opted for a more substantial design which is never a bad thing.

A basic overview of the HD7750 featuring the Cape Verde 28nm GPU Core. This card has 512 unified shaders, 16 ROPS and 1GB of GDDR5 memory connected via a 128 bit memory interface. The core runs at 800mhz and the memory at 1,125mhz (4.5Gbps effective).
