Testing:

OCC has a standardized testing procedure that the Sapphire HD 5770 FleX is run through to see how it stacks up to other video cards from ATI and NVIDIA. Three synthetic benchmarks and nine games provide the majority of test results with four common resolutions for all except 3DMark Vantage: 1280x1024, 1680x1050, 1920x1200, and 2560x1600. After a run through all of the tests the card is overclocked to near its maximum capabilities and then tested and compared all over again. Settings never change between video cards so the results are comparable, with the exception of disabling PhysX for all NVIDIA cards in certain tests, if disabled it is noted in the settings of the test. All testing is done on similar hardware running 64-bit Windows 7.

Overclocking:

Overclocked settings:

  • Sapphire Radeon HD 5770 FleX 980/1360

Overclocking the Sapphire HD 5770 FleX was a breeze! This card did not want to give up but it was difficult to pinpoint where it begun becoming unstable. The core went clear to 1000 MHz and ran through benchmarks but performance was decreased over 980 MHz so that is where the testing was conducted at while memory was set to 1360 MHz speed. The gains were 130 MHz on core speed and 160 MHz on memory speed, 15% and 13% gains respectively. A combination of AMD GPU Clock Tool and MSI Afterburner were used together since ATI Overdrive wouldn't allow for high enough speeds. The two overclocking programs had to be used together because Afterburner could only change fan speed and GPU Clock Tool could only change core and memory speeds, the two worked together flawlessly.

 

 

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.
