Club3D Radeon HD 7790 13Series 1GB Graphics Card Review
Chris Hadley / 12 years ago
Looking at the card, the one thing that is quickly noticeable is the apparent lack of any plastic shrouding that we typically find covering the heat sink. Instead what we find is an exposed PCB and circular heat sink which resembles the style of cards we used to find years ago. Hopefully this will not hinder temperature or acoustic performance too drastically.
Looking a little closer, the circular heat sink measures only 100mm across, whilst a 65mm fan sits in the middle. Two copper heat pipes rotate out from either side of the coolers base to draw heat away from the Bonaire core.
On the end of the PCB we find a single 6-pin PCIe power connector giving the ~85W of power that the Bonaire core requires.
Display outputs come with a standard array of options with both single and dual link DVI, HDMI and a full sized DisplayPort. Given the fact we don’t see any channelling for hot air through the card, there is not an amass of grills on the rear, but instead a single grill that does allow for some air throughput.
Like many other cards that I look at, the 13Series 7790 comes with a light factory over clock to give a little extra performance over reference speeds, and we see that the memory speeds have been left at the stock 1500MHz, whilst the core clock has been raised to 1030MHz.
