Sapphire Radeon HD 5670 Ultimate & HD 5550 OC Review



Testing on both the Sapphire Radeon HD 5670 Ultimate and the HD 5550 OC is done the same way as any other graphics card, once through stock speeds with Far Cry 2, Metro 2033, Crysis Warhead, Call of Duty Modern Warefare 2, Darkest of Days, Bioshock 2, Just Cause 2, Unigine Heaven Benchmark 2.0, Batman: Arkham Asylum, Resident Evil 5, 3DMark 06 Professional, and 3DMark Vantage. MSI Kombuster and Afterburner are used to measure the temperature at load and idle. All of these are then ran again after overclocking to a stable speed. Since this card falls into the low end tier, we use low settings so that performance may be more tolerable than forcing full quality settings on low end cards that were intended for mid and high end cards.



Comparison Cards:



  • Sapphire Radeon HD 5670 Ultimate

Overclocking the Sapphire Radeon HD 5670 Ultimate was quite simple, all that I needed to do was open up MSI Afterburner and begin to raise the GPU clock until it became unstable, which I could not go any higher than 850MHz on the GPU. The memory was also just as easy to overclock, I was able to raise it all the way up to 1050MHz. After a 10MHz raise on the GPU clocks, I would run a 15 minute stress test using MSI's Kombuster to check for stability at a 100% GPU usage, it if became unstable and crashed, I would back down to the most recent stable speed and begin with the memory clocks.





  • Sapphire Radeon HD5550 OC

The Sapphire Radeon HD5550 OC overclocking was very similar to the overclocking process of the HD5670, I would raise the clock speeds by 10MHz starting with the GPU until it became unstable then move onto the memory clocks. I was able to get the GPU all the way up to 780MHz before the core became unstable. Once I reached the maximum GPU clock, I moved to the memory, which was able to get all the way up to the same speed as the HD5670's memory as they both have the exact same memory modules, 1050MHz was the highest I could go.





Maximum Clock Speeds:

Each card has been tested for its maximum stable clock speeds using MSI's Kombuster utility. So far my testing has shown that higher clock speeds may be stable in games where GPU usage does not reach 100%, but will crash within a few minutes using this utility. The reported clock speeds are those that proved stable over a 15 minute test at 1920x1200 8x AA.
