Graphics card round up March 2013

Exactly the same ‘Core' artwork as the XFX R7770 box. No images of the R7850 on the front of the box which is unfortunate, as they are such an attractively designed solution.

XFX bundle a lot of literature with their cards, but sadly no converters or games with this one.

The XFX R7850 is longer than the R7770, built around a similar black PCB and black and silver metal cooler with XFX branding. It is a dual slot cooler.

The R7850 is Crossfire capable in a 2 way configuration. Ideal if you find you need more rendering power at a later date.

The R7850 takes power from a single 6 pin PCI power cable.

Underneath the shroud there is a separate circular Zalman style cooler, built around a single thick copper base and heatpipe which is bent in a circle through two racks of aluminum fins.

The XFX R7850 is built around the Pitcairn core, manufactured on the 28nm process. The core runs at 860mhz and the memory 1,200mhz (4.8gbps effective). AMD's HD7850 is much more powerful than the HD7770, featuring 2GB of GDDR5 memory connected via a 256 bit memory interface. There are 1,024 unifed shaders onboard along with 32 ROP's and 64 TMU's.
