Sapphire Radeon HD 7790 2GB OC Review


Sapphire HD 7790 2GB OC Conclusion:

After all the testing is done, the Sapphire HD 7790 2GB OC will offer up additional FPS performance when the settings are increased to take advantage of the larger frame buffer. Instances where running with a quartet of 4K monitors or when attempting to game at Eyefinity resolutions can provide some benefit over the 1GB-equipped cards. The most graphic example I saw in my testing of where the 2GB on this HD 7790 paid dividends was in the 3DMark Fire Extreme testing where this card proved without a doubt when the game settings are indeed high enough you do see a point of difference.

Just looking at the Sapphire HD 7790 2GB gives you the impression that it is a mini-me version of the HD 7970 Vapor-X. From the shroud to the functional backplate it just has that aggressive look. By using a backplate that is there for more than just looks, Sapphire has provided added functionality in the form of an innovative way to improve the cooling effectiveness of the backplate. By attaching a heat sink to the backplate and sending it up through a knock out in the PCB, it uses the airflow generated by the aerofoil fan to keep the memory ICs on the back of the PCB cool for improved long term stability.

Using a smaller cooling solution rarely pays off with improved or comparable cooling performance. At stock speeds the cooling is not as efficient as the Dual-X design used on Sapphire's 1GB model. However when the fan is ramped up to 100% it is right back in the game and falls only two degrees shy of the Dual-X results. This cooling performance helps the card stand out when overclocking with a final clock speed of 1240MHz over the baseline clock speed of 1050MHz; a 190MHz jump that provides additional FPS in game.

Connecting three displays to AMD cards usually requires the use of an active adapter that only adds to the costs associated with running three monitors. Sapphire has a select group of its product stack equipped with FleX technology that eliminates that added cost when running a three monitor Eyefinity setup for gaming or use as a single large surface workstation desktop. Sapphire's equipped the HD 7790 2GB OC with this technology as an added bonus for the end user. Up to four displays are supported in a 16K by 16K configuration.

Another added value proposition is that this card qualifies for a free game key for BioShock Infinte as part of AMD's Never Settle Reloaded game bundle. An added $60 value on top of the $25 to $30 you save not having to pick up an active adapter if using three displays.

Overall Sapphire continues to put out products that sets it apart from the pack with innovative cooling solutions and cards that meet the needs of the gaming community. When you look at the total package you get a card that looks good, performs and cools well, and has an added feature set for the same low point of entry. If you are gaming at 1920x1080 and want to run at high settings you can do so all for that for the same $159 price point as the 1GB versions with Sapphire's HD 7790 2GB OC.
