Introduction to the Sapphire Radeon HD 5550 Overclocked Edition

These days, we are witnessing a great abundance of video card releases. We have seen new models come from Nvidia in the form of the 4xx series, and with ATI we have seen them filling in the gaps of their current line-ups. Many will claim there is just too many on the market, I believe the number of cards on the market is a great way for individuals to pick just the card he or she needs and at the price in which they can afford. One of the major players in the video card market is Sapphire, as they have released their fair share of great cards. While  typically they release models based on the reference design, when it comes to non-reference models they are always ahead of the curve, which our next sample is a testament to that.

Sapphire’s take on the Radeon HD 5550 Series

“The SAPPHIRE HD 5500 series is based on the highly successful graphics architecture from the ATI division of AMD, built in its 40nm process. It supports the advanced graphical features of Microsoft DirectX 11, as well as on-board Stream Processing and video decoding, delivering superb video clarity and visual effects, whilst consuming very low power levels.

The SAPPHIRE HD 5550 family of graphics cards have 320 Stream processors and support Microsoft DirectX 11 as well as accelerating applications compatible with ATI Stream. SAPPHIRE now offers several new models with different memory configurations and display output options giving users a choice of card for different applications, and different budgets. As the core technology is low power, no external power connection is required, making this series ideal for system upgrades or mainstream PCs that do not have high end power supplies.”

Closer look

The Radeon HD 5550 OC comes based on Sapphire’s signature teal blue PCB, and is kept cool by an Arctic Cooling cooler. As you can see there is no humongous cooler on this model, as the HD 5550 is meant for those looking for a low power solution.  Other visual evidence of this being a low power GPU is the absence of a power connector. This is the result of the 40nm core technology which is the brain behind this card.

Here we have a close up of the Arctic Cooling supplied fan. The cooler uses an 80mm cooling fan atop an all aluminum block. The cooler is used to stabilize the 650MHz overclocked Redwood core, which as previously mentioned is upped 100MHz from the reference design.  The heatsink also cool the 512MB of GDDR5 memory. Sapphire does offer models of the HD 5550 with 1 GB of ram as well. The memory onboard here is clocked at 1000MHz (4000M/Ts).

Don’t let the single slot PCI expansion panel fool you since the cooler will most likely take up an adjacent slot on the motherboard. The rear of the card has all the video connection goodies you could ask for as well with HDMI, DVI and display port all being present. While there isn’t a cross bridge interface present, Crossfire is still supported through software if you feel so inclined.

Capcom Resident Evil 5
Capcom officially announced Resident Evil 5 on July 20, 2005. Jun Takeuchi, the director of Onimusha and producer of Lost Planet: Extreme Condition, took over producer duties from Hiroyuki Kobayashi. Keiji Inafune, who served as promotional producer for Resident Evil 2 and executive producer for the PlayStation 2 version of Resident Evil 4, oversaw the project.[26] In February 2007, members of Capcom’s Clover Studio were also called upon to help develop the game.

Capcom Street Fighter 4
All the characters and environments in Street Fighter IV are rendered as 3D models with polygons, similar to the Street Fighter EX sub-series Capcom produced with Arika. However, there are a couple of key differences. Art director and character designer Daigo Ikeno, who previously worked on Street Fighter III 3rd Strike, added cel-shading to give them a hand-drawn look, with visual effects accented in calligraphic strokes, ink smudges and ink sprays during the fights.

Power Consumption

The power consumption of this card, along with the rest of the build, was not too bad at all. Using an overclocked processor, a full-sized motherboard and this video card, the consumption maxed out at just over 157 watts total.


We were surprised to see this particular Radeon HD 5550 overclock as high as it did,  Considering the card was already overclocked from the factory a moderate 100MHz over reference cards. Letting ATI’s Control Center do the honors we were able to get the card up to 815MHz from the 650 in which it was clocked at. This was done without any voltage increasing, just playing around with the simple settings offered in CCC.


The Radeon HD 5550 OC is part of Sapphire’s newest budget line-up.  It is a smart buy for someone looking to upgrade from an older card, especially if their current card doesn’t have the feature set of a card like this. If digital video is a must for you then the 1080P support is great, watching movies or playing the newest video game is a great experience and have never been as good as it has now.  The latter will have its limitation of course, but we have seen in the testing the 5550 OC can game at moderate setting.

If you intend on using a card like this for connection to a large screen television, the video and sound quality is awesome. A far better choice than the on-board graphics that are coming on some of today’s motherboards.

Cards like the Radeon HD 5550 are big sellers due to their low price point. A card in this family would go for less than $100. And not only does it give the consumer various ways of connecting to your favorite display but it comes overclocked from the factory. A nice way to push the performance envelope and give the consumer more for his or her money.

If you are a quiet geek and want the least amount of noise coming in from your HTPC, then this is worth taking a look at. Sapphire did right by selecting Arctic Cooling to produce the heatsink for this card. Throughout our testing we could not hear the card, once again making it ideal for the home theatre buff.

However, if you are expecting to see a lot of accessories in the box coupled with the card, you will be disappointed. The card comes shipped with just a manual and nothing else. There are neither video adapters nor cables. This allows the card to keep it’s low-end price point. Drivers can be had from the web.
