Consumer Ultra-Low Voltage (CULV) is a computing platform developed by Intel. In January 2009, it was estimated that this market could reach 10 million CULV laptops shipped this year.[needs updating] Competing platforms include the VIA Nano, AMD Yukon, the AMD Nile notebook platform, and Nvidia GeForce series graphics chips within the “Nvidia Ion platform”. Some of the lowest power processors for the ultra-thin CULV category consume only a few watts more than the Intel Atom, which is rated at 2.5 W or less. Because of their low power and heat dissipation, CULVs enable very thin computer systems and long battery life in notebooks, such as those designed to Intel’s Ultrabook specifications.
While the first processors in this category were single-core processors (such as the SU3500), newer CULV processors are dual-core processors they are all based on the Intel Core 2 architecture, but the ultra-low-voltage versions have a thermal rating of 5.5 W – more than the Intel Atom, but a fraction of Intel’s dual-core mainstream mobile chips at 25 and 35 watts – and they come in a small 22-mm chip package.
Consumer Ultra-Low Voltage (CULV) processors are a class of Intel processors for ultra-light notebooks and embedded devices. CULV processors are designed to consume less power, so the notebook battery lasts longer and the notebook generates less heat. CULV laptops can be built thinner and lighter than conventional laptops with traditional processors. CULV processors do not heat up so much that the case needs to be equipped with a fan or other cooling components.
