Intel Core i3-330M vs Intel Core i3-380M

Intel Core i3-330M

► remove Intel 330M

The Intel Core i3-330M is a lower-middle class dual core CPU for laptops and clocks with 2.16 GHz. The difference to the Core i5-430M is the lacking Turbo Boost overclocking and the slower core speed. 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 i3-330M is the integrated graphics card called Intel HD Graphics or GMA HD and a DDR3 1066 MHz 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 in synthetic benchmarks is mostly on par with a 2.4 GHz Core 2 Duo P8600 (due to the improved hyperthreading). The speed should be at least as fast as a 2.2 GHz Core 2 Duo and therefore the i3-330M positions itself in the middle class (lower middle class regarding Core i CPUs). It should handle all applications well, but some demanding games could profit from a faster CPU.

The 32nm cpu cores of the Westmere generation can also process some new instructions to accelerate AES encryptions. In the i3-330M Intel has deactivated these new AES functions.

The integrated Intel Graphics Media Accelerator HD (GMA HD) graphics card is known to be clocked up to 500 MHz 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. A GeForce 9400M (ION) should still be a faster (especially as Nvidia and ATI cards have a better driver support than Intel up to now). According to rumors, the GMA core will also use the Turbo Mode regulate the clock speed.

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 i3-380M

► remove Intel 380M

The Intel Core i3-380M is a middle class dual core CPU for laptops and clocks with 2.53 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). It is part of the Arrandale refresh and successor to the 2.4 GHz i3-370M.

A feature of the new Core i3-380M 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 i3-380M should be at a level of a 2.6-2.7 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).
