The HIS HD 7790 iCooler Turbo 1GB is very nice package at a fair price. The main selling points the low price and solid performance. You can get one for as low as €122. However, if you feel like pinching pennies, we recommend you go for the non-Turbo version which costs a bit less, but it uses the exact same PCB and cooler. Judging by our tests, the iCooler is more than adequate to cope with reference clocked or overlocked HD 7790 cards.
The factory overclock did not result in any noteworthy performance gains, but once we tried tinkering with the clocks we managed to hit 1290MHz for the GPU and 1750MHz for the memory. The bumped up clocks did not have a big effect on the fan speed, the GPU stayed quiet and there wasn’t much noise, either.
AMD designed the HD 7790 to fill the gap between the HD 7770 and HD 7850 and it did a pretty good job. Judging by our tests, the HD 7790 iCooler Turbo is sufficient for gaming on resolutions up to 1680x1050, with high detail settings and antialiasing. At 1080p it is still possible to have some fun, but with less antialiasing and details. It is still possible to get a good balance between performance and image quality at 1080p, which is pretty impressive for such a low-cost GPU.
The HIS HD 7790 iCooler Turbo has plenty of overclocking potential, it ships with a top notch cooler and it costs about 6 euro more than the reference clocked HIS card, which is an equally good choice.
