Sapphire Radeon HD 7770 OC Vapor-X 1GB Graphics Card Review

Noise is generally the bain of most consumers lives and in the hope of finding the quietest operation, we feel it’s necessary to show you the audio level of components. We use the same components throughout this test and use a sound level meter to record the audio level of the system with a passive graphics card installed. Once we have the level recorded with the passive card, we continue to change the graphics card for the one that we are testing. Due to us having the audio level recorded before installation, it gives us a guide to work with and shows that anything over our initial level is an audio gain.

As this card uses the Vapor-X cooler, it wouldn’t be right to not look at cooling performance. With that in mind, we start with acoustics and see the 7770 OC Vapor-X around 2-3 dBA quieter than the reference 7770 XT card. We also see it being one of the quietest cards we’ve tested recently.
