PowerColor 5770 PCS+ Vortex Review



The PowerColor HD 5770 PCS+ Vortex is tested in a standardized method where the video card is first run through nine gaming benchmarks and three synthetic benchmarks. The results are recorded and then the testing is repeated at an overclocked speed to see how much of an improvement can be expected from overclocking. All the test results are tallied up and placed into graphs on pages dedicated to each benchmark. The results can then be compared to other video cards with performance similar to the 5770. Settings used in the testing do not change for any of the graphics cards, so results can truly be compared to each other, and all testing is done on systems with similar hardware running the 64-bit versions of Windows 7.


Comparison Video Cards:



Overclocked settings:

  • PowerColor Radeon HD 5770 PCS+ Vortex 970/1360

Overclocking the PowerColor Vortex card was very easy - ATI Catalyst was able to handle clock speeds and fan adjustment without a hitch and with 100% fan speed, the card was able to run at 970 MHz core and 1360 MHz memory completely stable. There wasn’t much more headroom and 1 GHz core was unachievable as it caused freezing during 3D load. Memory had more room left, but was running pretty hot already, so I didn’t pursue higher speeds. Voltage control through software doesn’t appear possible, as GPU-Z or any other video card software I tried didn’t report voltage levels or real fan speed, only set speed so the fan likely is only a two-wired fan (no RPM wire). Considering reference clock speeds are 850 MHz core and 1200 MHz memory, these are great overclocks.



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.
