Intel Core i5 vs. i7

For many consumers who want to buy a new PC or Laptop PC, one of the biggest question is related to the configuration i.e. type of Processor and memory. Top most Two CPUs often in considered for PC are the Intel Core i5 and Intel Core i7.

Intel’s Core i5 and i7 processors are faster in market, power efficient and better designed for modern computing than any others CPU. Now in world huge number of laptops and desktops consists of   i5s and i7s processor.

This post is written to help you decide whether you need to purchase the Core i7 or Core i5 based on different factor such as integrated graphics, clock speed, and hyper threading.

Price:

When we consider the price, there’s a clear difference between the two series, with some of the i5 chips are cheap as compare to i7 chips. Core i5-equipped systems will be less expensive than Core i7-equipped PCs.

Higher clocks: 

The clock speed is a common measure of how quickly each core on a processor can handle operations. so a higher clock speed means better performance. Intel’s dual-core i7 chips typically have higher clock speeds than their Core i5 counterparts, even at the same TDP. The fastest dual-core Core i7, which runs at 2.6GHz base and 3.2GHz standard. Where fastest Core i5 has a base clock of 2.3GHz and a max clock of 2.9GHz. The Core i7 processors have more capabilities than Core i5 CPUs.

Core:
For the most of operation, you'll get faster CPU performance from Core i7 than Core i5. The mostly of Core i7 desktop CPUs are quad-core processors, while many mobile Core i5 processors are dual core. This is not always the case, it may be dual-core mobile Core i7 processors and several quad-core desktop Core i5 CPUs.

More cache: 
Core i7 chips available with either 6MB or 4MB of cache. Core i5 chips available with 3MB or 4MB of cache. The i5 processors have in modern terms, when it comes to cache, this number smaller than most i7 processors by 2MB so it help the processor deal with repetitive tasks faster.

Hyper-Threading:
Hyper-Threading technology uses multithreading technology to increase performance on multithreaded tasks. The multithreading means a user running several programs simultaneously, but there are other activities that take advantage of Hyper-Threading, like multimedia operations.
In Hyper-Threading simplest situation is each core on the processor is capable of handling two threads instead of just one. Hyper-Threading technology is not found on Core i5 desktop chips. Where All Core i7 processors is build with Hyper-Threading technology, which means they all can handle twice as many threads as they have cores.
