Testing:

Testing of the Sapphire HD 7950 FleX Dual-X 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 11 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 Sapphire HD 7970. Other NVIDIA comparison cards will be using the 296.10 drivers; AMD will be using Catalyst 12.4 drivers.

Overclocking:

  • Sapphire HD 7950 FleX 3GB — Core 1131MHz, Memory 1558MHz

Overclocking this video card is as simple as booting up the Sapphire TriXX utility and moving some sliders around. I started at a baseline of 1050MHz on the core and 1500MHz on the memory. I took bigger steps on the core, making the jump from 1130MHz to 1150MHz and began to saw artifacting and snow start to show up. Backing down 5MHz at a time, I regained stability at 1135MHz, but I took it down another 4MHz to be conservative. The memory performed great and was rock stable until 1560MHz where it basically hit a wall. A few MHz here separated the memory from running great and complete failure. Compared to other HD 7950s, the clock speeds presented by this one aren't as impressive — although the idea to this card is multimonitor support and not raw overclocking potential right out of the gate.

 

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 and tests are rerun until they pass a full hour of testing.
