HIS 7790 iCooler Turbo 1GB (H779FT1GD)
The product box is large and vertical. There’s a picture of a sword, a Turbo sticker, and some key product information on the front of the packaging.
AMD’s technologies and system requirements are described on the back of the box. You can also see a list of awards from mass media there. The card is shipped together with a drivers and utilities CD, a DVI->D-Sub adapter, an installation guide, and a computer transportation notice.
The card is manufactured in China and costs $130, which is very inexpensive compared to the two products discussed above. The warranty period is 3 years.
The HIS 7790 iCooler Turbo is exceedingly simple. Its face side is covered by the cooler’s plastic casing with a small fan in the center.
The casing is larger than the PCB by 37 mm, making the card longer. It is a shame as the product might have been even more compact than its current 210 mm.
The HIS version has a standard set of video outputs…
…MIO and power connectors:
The PCB follows the reference design with a NCP81022 controller:
Manufactured on the week between the GPUs of the ASUS and Gigabyte cards, this chip lacks a protective frame, too.
Surprisingly, its 3D clock rate is 1075 MHz, too. So, we’ve got three almost identical GPUs so far. Its ASIC quality is somewhat different, though, at 70.1%.
The HIS card has 1 GB of memory in the same Hynix chips as we’ve seen on the ASUS and Gigabyte cards:
The memory is pre-overclocked from 6000 to 6400 MHz in 3D applications, making this card one of the fastest three in this review. The GPU-Z utility shows us the full specs:
The HIS 7790 iCooler Turbo has a primitive cooler: a piece of aluminum with a copper base and a 75mm fan.
There’s a heatsink on the power components, cooled by the same air flow.
The HIS card is considerably cheaper than the above-discussed products from ASUS and Gigabyte, so its cooler is low-end, too. Reaching a fan speed of 1880 RPM in the automatic regulation mode, the cooler kept the temperature at 68°C, which is higher than the GPU temperature of the ASUS or Gigabyte.
Auto fan mode
Maximum fan speed
At the maximum speed of 4190 RPM, the peak temperature was 62°C. Notwithstanding the humble cooler, the GPU could be overclocked somewhat better, by 175 MHz, than on the previous cards.
The memory chips were only stable at 6640 MHz, though:
Working at 1250/6640 MHz, the HIS 7790 iCooler Turbo had a GPU temperature of 70°C and a fan speed of 1920 RPM.
