Sapphire HD7790 2GB: Beefing up the Midrange Monster


The HD7790 GPU has proven itself to be a very capable offering and now with 2GB available its even better.

The choice to lower the clock speed puzzles us when we have seen every tested HD7790 hit the 1200Hz mark without even trying. We wonder why Sapphire would choose to lower the clock speed in comparison to the 1GB model, which in some tests, makes the card look like a lower performing card due to how the program works with the GPU in coordination with its GPU speed.

The addition of the extra 1GB of framebuffer means that if you utilize multiple displays or even opt for a CrossFire configuration you will have much more memory to feed these hungry GPUs.

Overall the ability to overclock means these cards can see up to 6-11% performance increases depending upon the game/app, but out of the box it is a bit slower.

With the ability to CrossFire two cards together, 2GB framebuffer, and excellent overclockability, this is a very good option for any gamer looking to build a modest but powerful gaming rig. Add in the great design with the backplate and how it is built to help dissipate the thermal from the memory ICs, and this card is a winner.
