Difference between i5 with 1.6 GHz and i3 with 2.3 GHz

Date: 26 Aug 2014    Group: Computers & Smart Devices    Category: Laptops & Tablets   

I have checked out some laptops for buying but I have a doubt regarding processor version and clock speed of processor. I just need to know, is the performance of an i5 processor with less clock speed say 1.6 GHz the same as an i3 processor with a higher clock speed say 2.3 GHz?

So, if I want to choose one of these two laptops which one would be better? the one with a higher clock speed or the one with the higher version of processor?

How does the performance vary between i5 and i3 computers? Is it worth going for an i5 laptop? Find out which gives better value for money.

Performance wise i5 4200U with 1.6 Ghz clock speed with work better. It has a max memory configuration of 8GB which is less than the i3 2.3 Ghz capacity of 16 GB but you rarely would run anything that would demand so much memory.

In matter of power consumption, i3 will take less power than i5 4200U.

If you want to select between these two then I would suggest you go for i5 4200U which is giving a clock speed of 1.6Ghz for better performance as power consumption in most cases is not a big priority and then, the difference between the power consumption between these two processors will give you only a extra power of around 15 minutes after full charge.

I used Intel Core i5 4200U and Intel i3 2350M processors for comparison. Both are dual cores and run at the specified clock speeds.

These are my observations.

1. When it comes to performance there is a slight domination by i5 processor even though at 1.6GHZ.
2. i5 Processor consumes more power when compared to i3 processor.

Its better to go for Intel i5 processor because performance plays more important role when compared to power consumption as said by Ankit.
