HIS iCooler Turbo HD 7790 reviewed

Review: Good OC potential and cooling

Today we’ll take a closer look at a factory overclocked HD 7790, courtesy of HIS. The HIS HD 7790 iCooler Turbo graphics card is cooled by HIS’ in-house iCooler which should keep the temperatures in check while providing silent operation.

The HD 7790 is based on AMD’s new Bonaire core, which fits snugly in between the HD 7770 and HD 7850. The new Bonaire GPU is a 28nm CGN part, optimized for superior power efficiency.

HD 7790 iCooler Turbo’s GPU is clocked at 1075MHz, while the memory ticks at 6400MHz. The reference core speed is 1000MHz, and the reference memory speed is 6000 MHz. HIS also has a reference clocked iCooler card. This means that only the difference between the plain and "Turbo" card are tuned up operating clocks (+75MHz for the core and 100MHz for the memory). The overclock is not spectacular, but we believe it is controlled by AMD. Other AMD partners came up with the same factory overclock but not one of them dared to push his card further. In our overclocking tests we will prove that the card is capable of attaining much higher clocks than 1075MHz.
