On the lookout for a higher-end graphics card, but value both temperatures and acoustics? MSI, with its Radeon HD 6950 Twin Frozr III Power Edition (*phew*) may have just what you’re looking for. In our tests, it often settled right beside more expensive offerings, and where acoustics and temperatures are concerned, it can’t be beat.

Power & Temperatures

To test our graphics cards for both temperatures and power consumption, we utilize OCCT for the stress-testing, GPU-Z for the temperature monitoring, and a Kill-a-Watt for power monitoring. The Kill-a-Watt is plugged into its own socket, with only the PC connect to it.

As per our guidelines when benchmarking with Windows, when the room temperature is stable (and reasonable), the test machine is boot up and left to sit at the desktop until things are completely idle. Because we are running such a highly optimized PC, this normally takes one or two minutes. Once things are good to go, the idle wattage is noted, GPU-Z is started up to begin monitoring card temperatures, and OCCT is set up to begin stress-testing.

To push the cards we test to their absolute limit, we use OCCT in full-screen 2560×1600 mode, and allow it to run for 15 minutes, which includes a one minute lull at the start, and a four minute lull at the end. After about 5 minutes, we begin to monitor our Kill-a-Watt to record the max wattage.

In the case of dual-GPU configurations, we measure the temperature of the top graphics card, as in our tests, it’s usually the one to get the hottest. This could depend on GPU cooler design, however.

Note: Due to changes AMD and NVIDIA made to the power schemes of their respective current-gen cards, we were unable to run OCCT on them. Rather, we had to use a less-strenuous run of 3DMark Vantage. We will be retesting all of our cards using this updated method the next time we overhaul our suite.

On the temperature side of things, MSI’s card impresses. It almost matches the super-low-end Radeon HD 6450, and that says something. It even beats out MSI’s own GTX 560! Hitting about 60°C on a $300 GPU is quite nice, given we’re used to seeing temperatures about 20°C higher. Power-wise, MSI’s card manages to suck down a bit more than the reference card, though it’s to be expected with its overclock. It does however manage to idle just the same.
