Graphics card round up March 2013

The XFX R7770 Core Edition ships in an artistic looking box featuring a 3D render of the word ‘CORE'. A nice high resolution image of the product wouldn't go amiss, we think.

A rather disappointing bundle, a ton of literature on the XFX power supply range, fitting instructions and a ‘Do Not Disturb' sign for a door handle.

The XFX R7770 is a tiny little card based around a black PCB. The XFX branded metal cooler is attractive and is finished in a silver and black colour scheme. A single large fan is positioned in the middle. This is a dual slot card.

The R7770 is Crossfire capable in a 2 way configuration. The R7770 has proven popular with users who buy a single card, then add another later for added horsepower.

The R7770 requires power from a single 6 pin connector.

The R7770 is fully loaded, with two DVI ports and a full sized HDMI and DisplayPort connector.

As we know from past experiences, AMD's HD7770 doesn't require a substantial cooler. XFX have opted for a small circular cooler, made from metal and painted black. It resides directly over the core underneath with the remainder of the card cooled actively via the fan.

Above, we can see an overview of the Cape Verde hardware built on the 28nm manufacturing process. The R7770 core is clocked at 1GHZ and the memory @ 1,125mhz (4.5Gbps effective). The HD7770 is bandwidth limited, featuring 1GB of GDDR5 memory connected via a 128 bit memory interface. There are 640 shaders onboard and 16 ROPS/40 TMU's.
