Intel Core i5 for the laptop, how to choose the best processor in this category

Intel Core i is the new processors in 2010 and came to replace the Core 2 family processors such as Core 2 Duo and Core 2 Quad. Of chains in the new processors are a series Core i5. We'll take a look at this article in the buyer. Com and how these processors choose from.

In the beginning, there are several series which is the i7 and the i3 and the i5. We will devote this article for the i5. Alkor i5 class came to replace the Intel Core 2 Duo, and no doubt you have started to see the new processors in each place in the laptop market.

Differences between the Core i5 and Core 2 Duo:

1 - Use less energy, where it manufactured the 32nm technology, which is less heat and energy from Alkor 2 Duo, which is usually 45nm or 65nm

2 - Strengthening the graphics card built in the new generation, and transportation of motherboard for the processor.

3 - the Turbo Boost technology in the i5, which allows the processor to work quickly and increase the default maximum speed only when needed, which saves energy instead of using the full processor power without need.

4 - The Technology Hyper-Threading, which allows for dual-core processor to work similar to the quad-core processor.

How do you choose?

Intel has facilitated it this time, in the past, the Alkor 2 Duo contains a number of sub-categories, each category contains a number of models with several differences between the classifications and models make matters complicated for the buyer. This time you will find less complexity with a focus only on the speed difference.

In the history of writing this article you will find these models for the individual user in the laptop:

Core i5-540M: Dual-Core / Speed ​​2.53Ghz / turbo speed after 3.06Ghz / Cash 3 MB / 35 watts

Core i5-520M: Dual-Core / Speed ​​2.4Ghz / turbo speed after 2.933Ghz / Cash 3 MB / 35 watts

Core i5-430M: Dual-Core / Speed ​​2.26Ghz / turbo speed after 2.533Ghz / Cash 3 MB / 35 watts

After that you will find a low-power processor for use in devices slim and light and noted the letter U in the name of the processor, which indicates that low-energy "Ultra-Low Voltage"

Core i5-520UM: Dual-Core / Speed ​​1.066Ghz / turbo speed after 1.866Ghz / Cash 3 MB / 18 watts

The latter is a little like very 520E of the 520M, but with a slight difference in the way the memory and the user does not care about an individual matter, but some special uses.

If it can be said that there are currently three formal treatments you can choose from, each of the three processors are identical in the specification, the only difference is the speed of the processor, what determines your choice? The budget.

And by virtue of the processors are identical in specifications and the only difference is the speed, you will not find a significant difference between species, especially the third and you rarely will need to already full processor speed, so it can be said that the three processors are close together in most cases and applications.
