Sometimes a video card needs to be just that. A card for video. Many high-end workstation motherboards don’t have integrated video, but what good is a computer without a display?

The Intel i7 is just the perfect example. A lot of people have the need for quad cores of number-crunching power, but they’re not gamers (we’ll convert you yet, we’ll start slow, like with a relaxing, if hypnotic game of 99 Bricks, followed by a little retro-tastic Gravity Hook. Toss in a few hours of Desktop Tower Defense, and you’re inches away from being neck-deep in Assassin’s Creed) and, appropriately, have no desire to own a beautiful set of GTX 50 millions. (But you’ll get there, we’ll see to that.).

And the Radeon HD 4550 is a perfect example of such a video card. It’s on par with really, really good integrated graphics, and Sapphire’s is half-height (and includes a half-height bracket for the SFF-bound) quiet enough, and consumes about zero watts of power. If that’s your speed, there’s almost nothing you could ever find wrong with an HD 4550. Everyone else, though, move along, nothing to see here.

The Card & Bundle

Like any well-behaved stick of Sapphire hardware, this card has a blue PCB. Unlike damn near any other card on the market, the heatsink is a tiny aluminum disk with brief fins and a fan right in the center. I haven’t seen a fan like this in years, it takes me back. In fact I wonder why this card is actively cooled at all, I’d think a chunky bit of aluminum would be cheaper than a dinky bit and a fan, but then, I don’t make ‘em, I just bench ‘em. Sapphire does, at least, offer a passively-cooled model of this video card.

This short card barely reaches the end of the PCI-Express slot, and is half-height, which means that all you need to do to make it fit in a short case is to swap out the expansion slot bracket for a short one. Good thing there’s one in the box, along with a driver disk, some paperwork, some instructions, a video-out adapter, a VGA adapter, and love.

DirectX 10 Titles

Performance Notes

This card is almost incapable of playing recent titles. Not that it’s intended to.

DX9, OpenGL, and Synthetics

Performance Notes

With older titles, things pick up a little, but are in no way praiseworthy.

Video, Power, and Overclocking

Of course, Sapphire’s HD 4550 has no problems with video playback, as all HD 4000 cards have ATI’s UVD–impressive perfect scores with a very small amount of room for improvement.

This card isn’t silent, you’d have to use a third-party fan control utility to slow down the fan’s speed to that point. But it’s pretty quiet, getting beaten out for noise production by other components of the test bench. For workstations, that’s probably a non-issue, but if you’re interested in this card for video playback (and not gaming) then seek out the fanless version.

Power consumption, on the other hand, is alarming. Alarming good, not alarming bad. This card sets a new record for low power consumption, without compromising on the other features it sets out to perform. That is to say, it drives a monitor, it plays some video, and it consumes almost no electricity.

There are no overclocking options available to this video card in the Catalyst Control Center, but then, what’s the point of that? I think there’s a built-in limit to the speed at which Aero renders.


Like I said, this card delivers. Not on games, though, you’d want to avoid any of that for the welfare of your brain. But it plays video just fine, it’s happy to run a couple of monitors, and it’s half-height with accompanying hardware to fit any size chassis.

But the massively-parallel stream-computing powerhouse just isn’t there. This video card is essentially just integrated graphics for a desktop computer. Which, by its own right, is fine. That’s all some people need, anyway.

This card’s purpose is for workstations to have some way to run a display. If you’re building a home theater PC, this hardware has all the right functions but loses on the aesthetic, just because it has a fan. Fortunately for you, Sapphire also sells one that’s fanless. Just buy that one instead.
