Intel Core i3-330UM vs Intel Core i3-380UM
Intel Core i3-330UM
► remove from comparisonThe Intel Core i3-330UM is a Ultra Low Voltage dual-core processor for small and light laptops. It is clocked with 1.2 GHz and does not feature Turbo Boost to overclock the CPU cores. Another feature missing compared to the i5 and i7 lineup is the AES function block. Each core is based on the Nehalem (Westmere) micro-architecture. Hyperthreading enables the Dual Core CPU to handle 4 threads at once (for a better usage of the pipeline).
A feature of the new Core i3-330UM is the integrated graphics card (called Intel HD Graphics) and memory controller. Both are on a separate die that is still manufactured in 45nm whereas the CPU die is already manufactured in the new 32nm process. The also called GMA HD is able to use Turbo Boost to overclock from 133 to 500 MHz.
Due to the integrated memory controller and HyperThreading, the Core i3-330UM is faster than a similar clocked Core 2 Duo (1.2 GHz) in all (us known) applications and benchmarks. Therefore it should beat the 1.3 GHz Pentium SU7300. Still the gaming performance will suffer from the low clock speed.
The power consumption of 18 Watt TDP (max.) counts for the whole package and therefore it is clearly better than the 17 Watt TDP of the Core 2 Duo SL-series (CPU alone).

The similar Core i5-470UM, i5-560UM, and i7-660UM are also clocked at a base speed of 1.3 GHz, but feature Turbo Boost and are therefore faster.
