“The first question you may ask yourself is, “What makes a low voltage part?” A standard Intel Xeon (Woodcrest) is rated at 80W TDP, and their low voltage parts are rated at 40W TDP. Most of AMD’s Opterons operate at 85W TDP and their low voltage parts come in at 68W TDP. At first glance, it would appear that Intel servers should utilize less power than AMD, but that would be an incorrect assumption. Given the many components that make up a server (especially memory), and the difference in how each vendor handles their different power states, there is more to low voltage than meets the eye.”

AMD and Intel seem to currently be in a race to see who can use the least amount of power, especially when it comes to servers. Instead of measuring who is the fastest, or the most powerful, AnandTech’s review focuses on the power consumption of Intel and AMD’s low power chips, when performing an identical task. Whether you are looking to lower your power costs, or even just trying to figure out what TDP means to you, this article will help you along your way.
