Intel Core i3 vs Core i5 Processor

Posted by Stefan on October 7th, 2010 in Uncategorized | 1 Comment

Most of the latest desktops and laptops available these days are fitted with either Intel core i3 or core i5 processor. The main difference in the two processors basically lies in if the turbo boost technology has been used or not.

Turbo Boost technology:

This technology is a technique to enhance the frequency of a core processor according to the necessity. As for example, the usual core frequency in Intel i5-450 processor is 2.4 Giga Hertz. This frequency can be boosted up through the turbo booster to 2.66 GHz. It implies that the central processing unit normally runs on 2.4 GHz, but when the processor requires very high power for computing, the core frequency will be increased to 2.66 GHz to handle the additional power necessitated by processor.

The turbo boost technology assists in two ways. First it maintains low power consumption under control and increases the processing speed. The battery power is saved and the processor gives optimized top performance with high battery life. Due to the difference in technology involved i5 core processors are costlier in comparison to i3 core processors. In case your computing needs require more power frequently such as you need to do video encoding or compiling of a few programs, etc. in that case i5 core processor is more appropriate for your needs. On the other hand, if your requirements are just for basic use such as word processing, spreadsheet, or, demonstrating etc. you can go for i3 processor and save money.

.Another worth noting fact is that core i5 processors come in dual core and quad core. The dual core i5 processors are just alike i3 processors. But the quad core i3 versions are quite closer to dual core i7 processors.

Normally, i5-450m processor will cock 2.4 GHz. There are two major factors that will make it work faster than similar Core 2 processor. The first feature is its integrated memory controller. The processor is capable of directly communicating with the memory and has not to go through another chip. This increases its performance and reduces the latency.

The second feature that improves its performance substantially is its hyper threading as compared to core 2 duo. There are two threads in each processor and total four threads running help numerous processes to run simultaneously and improve the performance.

Now you are almost cognizant of the basic difference between the core i3 and core i5 processors and can buy your desk top or notebook according to your needs for a specific processor.

    I think we should wait for the Sandy Bridge processors to arrive. Just for core i3-250m or core i5 – I will wait for sandy bridge instead.
