Intel Core i3-380UM Mobile processor (CN80617005190AF)

Intel Core i3-380UM is the second ultra-low voltage (ULV) microprocessor from Core i3 Mobile family, aimed at ultra-thin and light notebooks. The CPU belongs to Nehalem group of CPU families, and is built on 32nm manufacturing process. The i3-380UM core design, codenamed Arrandale, combines two CPU cores and a graphics controller in one package. The cores operate at 1.33 GHz, and use integrated DDR3 memory controller for memory access, and Direct Media Interface for communications with peripheral devices. The graphics controller operates at 166 MHz. The main purpose of the i3-380UM processor is to provide low-power operation, therefore it employs various techniques to reduce power consumption, such as Enhanced SpeedStep technology, multiple low-power states, and lower (in comparison with standard-power mobile CPUs) operating frequency. For example, this i3-380UM is clocked almost twice as slow than Core i3-380M microprocessor. On the plus side, the Core i3-380UM has almost twice smaller Thermal Design Power, 18 Watt as opposed to 35 Watt for the 380M model. Performance enhancing features on this ULV CPU are:

• HyperThreading technology, that doubles the number of simultaneously executed threads,
• instruction set extensions, like SSE3 and SSE4,
• three-level caching, with 64 KB level 1 and 256 KB level 2 caches dedicated to each core, and 3 MB level 3 cache shared between the cores.

The Core i3-380UM microprocessor is manufactured in micro-FCBGA package, and it is typically soldered on a motherboard. Official launch of the Core i3-380UM model will likely coincide with release of other ultra low power CPUs, such as Core i5-470UM, Core i7-560UM and Core i7-680UM. Before the launch, the Core i3 Mobile i3-380UM model was spotted in several notebooks - Acer TravelMate 8172, Dell Inspiron 13z, HP TouchSmart tm2-2105tx, Lenovo IdeaPad U160 Laptop, and in Fujitsu LIFEBOOK T580 tablet PC. Some of these laptops were available for sale before Intel's official announcement of the 380UM and other ULV microprocessors.

The Core i3-380UM lacks many advanced features, present in more powerful i5 and i7 families. Compared to Core i5-470UM, the 380UM is short of Turbo Boost feature. Under certain conditions, this feature can boost 470UM CPU frequency up to 1.86 GHz. Compared to budget Pentium U5400 model, the Core i3-380UM ultra-low voltage processor has 133 MHz higher core frequency, and adds HyperThreading and Virtualization technologies.
