Throughout all of our benchmarking and testing with NVIDIA's Ion platform, we monitored how much power our test systems were consuming using a power meter. Our goal was to give you an idea as to how much power a few of our systems consumed while idling and under a heavy workload, versus the Ion platform.
Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the motherboards or processors alone. For this test, we loaded up both Cinebench and our 1080p Dark Night video clip to stress the CPU and GPU cores in the Ion system. Then we fired up ET: Quake Wars to compare notes between multimedia power consumption and gaming power consumption.
Finally, versus the other Atom-based products we tested, the Ion system did consume more power both at idle and under loaded conditions, but that was to be expected with the beefy GeForce 9400M drawing a bit more with its more capable GPU and video engine core.
