It does make a difference-an 8GB folder took about 10 percent less time. Note that we didn’t test GPU compute heavily, but it’s worth noting that the latest version of Winzip, Winzip 16.5, offers an option to enable OpenCL GPU acceleration to compress files. AMD’s focus on building a GPU that performs well in both graphics and GPU compute seems to have paid off.

DiRT Showdown is the first game shipped to use global illumination, plus other advanced lighting techniques. DirectCompute is also used for high-dynamic-range ambient occlusion shadow effects and depth-of-field calculations. Sniper Elite V2 uses supersampling plus DirectCompute accelerated antialiasing.
Now let’s turn to a couple of newer game titles that make heavier use of GPU compute. These are power ratings for a system with a 1200W PSU. The new AMD progeny is the same 11-inch length as the original both are a half-inch longer than the GTX 680. Note that the HD 7970 GHz Edition still uses the same power connectors as the first 7970-one 8-pin PCIe power connector and one 6-pin connector.
The GTX is more power-efficient than either card, at 119W idle and 318W under load.

However, PowerTune Boost, the higher core clock speed, and the faster memory does come at a cost-while idle power is actually a little better than the original, at 120W (versus 124W for the first Radeon HD 7970), full load power is a whopping 384W, over 18 percent higher than the 324W maximum power draw on the original HD 7970. The architecture hasn’t changed, and the AMD reference card looks nearly identical, right down to the display connectors and fan. All the game tests are reported at 2560 x 1600 pixel resolution with 4x multisampling antialiasing enabled.
