Review: AMD Radeon HD 7750 and HD 7770 + XFX Black Super OC Edition
by Damien Triolet

Noise, heat and infrared thermography
For this test we used the new protocol as described here.

Here first of all is a summary of all the readings:


The reference Radeon HD 7750 is rather noisy at idle while the XFX Double Dissipation model is really quiet.


In load, the reference Radeon HD 7750 is still the noisiest of the three cards, while the XFX model is the quietest. Once the two Radeon HD 7770s have been overclocked, the XFX card has an even bigger advantage.

Here’s what our thermal imaging showed:


Reference Radeon HD 7750
Reference Radeon HD 7770
XFX Radeon HD 7770 Black Super OC
  [ Idle ]  [ Load ]
  [ Idle ]  [ Load ]  [ OC ]
  [ Idle ]  [ Load ]  [ OC ]

In spite of the significant factory overclocking, the XFX Radeon HD 7770 Black Super OC Double Dissipation is better cooled than the reference Radeon HD 7770.
