HIS is a Hong Kong based PC component maker specializing in ATI graphics cards. They first grabbed our attention when they began selling cards with well-known and recognizable third party coolers pre-installed. Their IceQ series cards were perhaps the first high-end video cards that really ran cool and quietly without user modification as they utilized the famous VGA Silencers from Arctic Cooling. Today, similar stock heatsink designs on many high-end cards are based in part on the VGA Silencer. The last ATI card we examined was also a HIS: The HD Radeon 5870 iCooler V Turbo.


The boxes.

The trio of cards examined here aren't as fancy as some of the previous HIS models we've tested; in fact they are humble by comparison. They are from the HIS "Silence" line, based on lower-end ATI GPUs with low power requirements. While modest in 3D performance, they run much cooler, and so have a far greater potential for being cooled silently. We have a HD 5570 and a pair of HD 5550s, one full-sized, and one half-height, all cooled with fanless heatsinks. The lowest rung of the HD 5000 family is the HD 5450, a 6~7W card that excels at playing video but little more. Though hardly a gamer's delight, the 5550 and 5570 should offer a nice boost to those who prefer to game on a budget.


HD 5570, technical specifications according to GPU-Z.


HD 5550: fewer shaders, lower clock speed.


HIS' half-height HD 5550. DDR3 memory instead of DDR5.

One thing we should note is our half-height HD 5550 Silence 1GB sample didn't match the official specifications at the HIS website. According to the site, the card is saddled with DDR2 memory, but ours shipped with GDDR3. This discrepancy will likely improve its performance and power draw somewhat.
