Conclusion on Linux Benchmarks

I have to say that the benchmark numbers in Linux came as a bit of a surprise. The card wasn't far behind the Radeon HD4650, but still fell behind the numbers we got from the GeForce 9600 and 8800 series cards.

As always, it's well known that that AMD's Linux driver isn't the best. For proof, once can compare similar games in bot Linux and Windows and see where the card falls behind in Linux. That's partially the purpose of the review to look at how well AMD has implemented their driver.

Final Thoughts & Conclusion

Sapphire's Radeon HD4550 pulls its weight, despite being a mid-range card. The card doesn't fall far behind the Radeon HD4650 in terms of performance, and is priced slightly lower. On top of this, the card can fit both low-profile and full-profile systems. This makes for an ideal card for small-profile workstations or DVRs.

Linux performance wasn't particularly what I would have liked to have seen, but to be fair, it did perform as well as it performed in Windows. nVidia-based cards typically always perform above and beyond AMD cards in Linux, but this can usually be blamed on AMD's graphics driver in Linux. AMD has promised further improvements to the drive, so it's only a matter of time before we see equal performance in both Linux and Windows from ATI cards.

Sapphire definitely has a great mainstream card on their hands with the Radeon HD4550 overclocked. With DDR3 memory and the adjustable profile size, the card is sure to be a hit in the mainstream market, especially as the card is capable of playing today's latest games. For the price, performance, and usability of this card, we've awarded it our "#1 Recommended" award.
