Intel Core i3-390M vs Intel Core i3-380UM

Intel Core i3-390M

► remove

The Intel Core i3-390M is a middle class dual core CPU for laptops and clocks with 2.67 GHz. The difference to the Core i5 and i7 series is the lacking TurboBoost overclocking, and the missing AES, VT-d and Trusted Execution functions. 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 i3-390M is the integrated graphics card called GMA HD and the 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 performance of the Core i3-390M should be at a level of a 2.7-2.8 GHz Core 2 Duo (upper class CPUs in the last year). This is mainly due to the efficient HyperThreading function and the integrated memory controller. In single threaded applications it should be at least as fast, as a similar clocked Core 2 Duo.

The integrated Intel Graphics Media Accelerator HD (GMA HD) graphics card is known to be clocked up to 500-667 MHz (due to Turbo Boost) and should be clearly faster than the old GMA 4500MHD. The Core i5 and i7 models should still be a bit faster because of the higher max. clock speed of the GPU. The performance of the graphics in 3D should be on par with a Radeon HD 4200 but the driver support is usually worse.

The power consumption of 35 Watt TDP (max.) counts for the whole package and therefore it is clearly better than the 35 Watt TDP of the Core 2 Duo T-series (CPU alone).

Intel Core i3-380UM

► remove

The Intel Core i3-380UM is a Ultra Low Voltage dual-core processor for small and light laptops. It is clocked with 1.3 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). 

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.

A feature of the new Core i3-380UM 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 i3-380UM is faster than a similar clocked Core 2 Duo (1.3 GHz) in all (us known) applications and benchmarks. Therefore it beats the 1.3 GHz Pentium SU7300 and performs in some areas even as fast as a 2 GHz Core 2 Duo. Still the gaming performance can 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).
