XFX is a well known company among PC gamers and hardware enthusiasts. It is a division of PINE Technology Holdings Limited. The XFX manufacturing branch specializes in high-performance PC hardware with a focus on gaming products including AMD and NVIDIA graphics processing units and motherboards.

On our test bench today is the XFX Double D HD 7970 GHz Edition video card (FX-797G-TDFC). Note: To view the correct specs you will have to manually select the above mentioned video card from the list of HD 7970 GPUs.

AMD Radeon HD 7970 GHz Edition

AMD released its first of the next generation GPU with the Radeon HD 7970 on December 22nd, 2011, codenamed "Tahiti." This released ruled the market in both performance and price until NVIDIA released the GeForce GTX 680 which had better performance and a lower price. AMD continued its release of the Radeon HD 7950 on January 30th, 2012 and later on with the Radeon HD 7870 and 7850 video cards on March 4th, 2012, codenamed "Pitcairn."

On June 21, 2012, AMD refreshed the Radeon HD 7970 with higher clock speeds and GHz Edition branding. The biggest difference between the Radeon HD 7970 GHz Edition and a reference Radeon HD 7970 is the operating frequency. The reference design of the original 7970 has the GPU running at 925MHz and the memory running at 1375MHz or 5.5GHz GDDR5. The Radeon HD 7970 GHz Edition has the GPU running at 1000MHz base clock with a 1050MHz Boost Clock, while the memory is set to run at 1500MHz or 6GHz GDDR5. Both video cards still have 128 Texture Units, 32 ROP's, 128 Z/Stencils, and 3GB of GDDR5 memory on a 384-bit bus. The typical board power for each video card is 250 Watts.

The XFX Double Dissipation HD 7970 GHz Edition video card comes with default speeds for a GHz Edition video card, meaning no factory overclock. It will run at 1050MHz out of box with the memory running at 6GHz GDDR5. While XFX does not have its own overclocking utility, users will still be able to overclock this video card with AMD Overdrive which is included with the driver.

The biggest feature of the XFX Double D HD 7970 GHz Edition video card is the Double Dissipation technology. Instead of using several copper heat pipes that touch the GPU there is a large copper HydroCell piece that is designed to transport and dissipate heat via condensation wicks and evaporation wicks. The Double Dissipation system is designed to have one fan directly cooling the HydroCell and GPU, while the other fan cools the elevated heatsink, PCB, and other board components.

Another interesting feature that the XFX Double D HD 7970 GHz Edition video card supports are the HD/4K resolutions. We are usually limited to 2560x1600 on a single display, however this video card will support up to 4096x2160 resolution.

The XFX Double D HD 7970 GHz Edition is currently available at Newegg for $424.99 after rebates. You can read more about the XFX Double D HD 7970 GHz Edition's specifications here.
