A Closer Look


The Gigabyte HD 7790 WindForce OC 2GB graphics card uses a custom WindForce cooling solution with a pair of 100mm fans and two large aluminium heatsinks with a single large 8mm copper heatpipe transferring additional heat from the first to the second heatsink.

The PCB is traditional Gigabyte blue. You can see we have memory chips on the back because this uses 2GB not 1GB so needs the extra memory mounting points.

Underneath the fans you can see two different heatsinks. The primary larger one covers the GPU die and has a heat pipe carrying heat into the second heatsink which is slightly smaller and covers the VRM area. There is also a small heatsink on the far left for some VRM components.

The card has a pretty beefy design for a relatively budget HD 7790 GPU, it measures in at about 27cm or 10.5 inches.

In terms of thickness this graphics card comes in at a hair under two PCI slots.

Here more closely we can see that the second heatsink is slightly raised up to allow for the VRM underneath it to fit.

The end of the graphics card is open ended to allow for heat dissipation.

Out of the box the unit comes overclocked to 1075MHz, a 7.5% OC from the stock 1000MHz. The memory runs at default clocks.
