Testing:

Testing of the Sapphire HD 7770 Vapor-X OC Edition will consist of running it and comparison cards through the OverclockersClub.com suite of games and synthetic benchmarks. This will test the performance against many popular competitors. Comparisons will be made to cards of a range of capabilities to show where each card falls on the performance ladder. The games used are some of today's newest and most popular titles, which should be able to provide an idea of how the cards perform relative to each other.

The system specifications will remain the same throughout the testing. No adjustment will be made to the respective control panels during the testing, with the exception of the 3DMark Vantage testing, where PhysX will be disabled in the NVIDIA Control Panel, if applicable. I will first test the cards at stock speeds, and then overclocked to see the effects of an increase in clock speed. The cards will be placed in order from highest to lowest performance in each graph to show where they fall by comparison. The latest press release driver will be used in testing of the GTX 690 and GTX 680. Other NVIDIA comparison cards will be using the 296.10 drivers; AMD will be using Catalyst 12.4 drivers.

Overclocking:

  • Sapphire HD 7770 Vapor-X OC Edition — Core 1215MHz, Memory 1430MHz

Overclocking an AMD GPU is about as simple as it can get. I simply used Catalyst Control Center to raise up the GPU and memory clock speeds using the sliders. As with any overclocking using CCC, the PowerTune slider was slammed all the way to the maximum of +50%. With such high stock clocks it wasn't easy to push the card much further, maxing out the sliders was definately not an option like you might do with lower factory clocked cards. It was pretty easy to push the card up to 1225/1450 and run marginally stable -- but any part of not stable means it isn't worth running. I bumped it down to the 1215/1430 to run the benchmarks, which seemed to be a pretty solid overclock of this already pre-clocked beast. 

 

 

 

Maximum Clock Speeds:

Testing for the maximum clock speed consists of looping Unigine 3.0 for 30 minutes each to see where the clock speeds fail when pushed. If the clock speed adjustment fails, then the clock speeds are adjusted and the test is rerun until each card passes the testing.
