AnandTech has compared the AMD 780G, NVIDIA GeForce 8200 and Intel G35 IGP chipsets. This time they don't focus on performance but on power consumption.
Notice we say platforms. Yes, the chipsets are a very important factor in the overall power consumption of a system, though the main watt robbing items are generally the CPU and GPU. In addition, the number of storage devices, cooling apparatus, and the power supply all play an integral part in the ecosystem we like to call the personal computer.
Our quick look today is by no means a comprehensive review of system power consumption; instead, we are providing an additional focus on the power requirements of the three latest IGP solutions available in the market. We felt like this information would get lost in the multitude of pages in the forthcoming roundup, so a sidebar article seemed appropriate. The results today will provide an extra glimpse into the platform differences when using the same exact components on the AMD side sans the motherboard/chipset and competitive offerings from Intel for comparison. We plan to do the same for our video comparisons between these platforms.
You can check it out over here. The tests aren't really conclusive as they only tested three motherboards but overall the system with the NVIDIA GeForce 8200 IGP seems to consume the least power. The reviewer also didn't test the performance of the chipsets but he says a IGP performance per watt article will be published soon.
