Sapphire Radeon HD 7750 Low Profile Review

» Discuss this article (15)


Power consumption of the system will be measured at both idle and loaded states, taking into account the peak wattage of the entire system with each video card installed. I will use Unigine's Heaven Benchmark version 3.0 to put a load onto the GPU using the settings below. A 15-minute load test will be used to simulate maximum load with the highest measured wattage value recorded as the result. The idle results will measured as the lowest wattage value recorded with no activity on the system.


  • Unigine 3.0 Heaven Benchmark
  • 1920x1080 Resolution
  • 8x AA
  • 15-minute load test
  • 15-minute idle test
  • Measurement is in watts













At stock speeds this little 7750 really sips the juice delivering the lowest load wattage of any card in testing. Things change when cranking up the power, though as the overclocked wattage jumps by 75 watts or so! No wonder that little heat sink got so hot; the 7750 is pulling over double its stock TDP at these settings! It even surpasses the overclocked Sapphire HD 7770 by almost 40 watts.
