Sapphire HD7770 GHZ FleX Edition Review

Here she is again, the famous, well endowed ‘Sapphire' army lass, looking equally moody and fierce with a barbed wire tattoo on her arm. That would normally be enough to get the young geeks salivating at the mouth.

For a budget oriented card this bundle is actually quite impressive. Sapphire have bundled a high grade HDMI cable, various power and video converter cables, a software disc, and a quick start guide.

The Sapphire HD7770 Flex Edition is built on a bright blue PCB with a black plastic cooler covering the full length. In the center is a single, large fan with the FleX branding on both shroud and cooler.

The card is Crossfire capable in a two way configuration only. If you want three or Quad Crossfire configurations you are expected to buy a HD79xx series card.

Power is supplied from a single 6 pin PCI power connector.

This is a dual slot design with two DVI connectors and a single full sized HDMI and DisplayPort. It is Eyefinity capable and can power up to 6 displays. This solution can simultaneously output multiple, independent audio streams from the HDMI and mini Displayport connectors at the rear of the card. The GPU can support 3GHz HDMI with frame packing support for Stereo 3D.

Sapphire have adopted a simple heatsink which is based around two thick copper heatpipes which run into separate racks of aluminum fins on either side of the base. They are using high quality ELPIDA GDDR5 memory for this card.

An overview of the hardware via GPUz. The Cape Verde core is built around the 28nm manufacturing process, with a core clock of 1,000mhz. The 1GB of GDDR5 memory is connected via a 128 bit memory interface. The card is equipped with 16 ROPS and 640 unified shaders. This is no powerhouse gaming card, but should cope with many titles at 1080p.
