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 HD4850, 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 implimented their driver.

Final Thoughts & Conclusion

For a mid-range video card, the overclocked Sapphire Radeon HD4650 pulls its weight. At a reasonable form factor and pricing point, the Radeon HD4650 packs a punch. Consider the fact that up to four HD4650 cards can be used in parallel with AMD's CrossFireX technology to improve performance further.While the card did fall behind in performance to the GeForce 9600 GSO, the Radeon HD4650 offers a better pricing point, and also features some technologies not found in the GeForce 9600, such as DirectX 10.1 support.

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 HD4650 overclocked. With the overclocked memory and GDDR3, the card is sure to outperform vanilla HD4650 models, and should be able to play many of today's popular games at reasonable settings without giving up too much detail.
