Power Consumption and Operating Temperatures
How low can you go?
We'd like to cover a few final data points before bringing this article to a close. Throughout all of our benchmarking and testing, we monitored how much power our test system was consuming using a power meter. Our goal was to give you an idea as to how much power each configuration used while idling and under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the graphics cards alone.
Although it features a faster core clock and more onboard memory, the V9800 shows lower power consumption than the V8800. Out of all the cards tested, it even showed the lowest usage in an idle state. At full load, it required 16% less power than the Quadro 6000.
The V9800 turned in impressive temps during testing. At full load, it maxed out at 73 degrees Celsius, 15 degrees cooler than the Quadro 6000.
Also, its worth mentioning the noise level we experienced using the V9800. Ultimately, the V9800 provided a quiet working environment during testing. Fan speed remained about 20% during most benchmarks, which is extremely quiet. In fact, we still could not hear it during our load testing with Furmark, where fan speed increased to only 30%.
