Intel Core i-3, I 5, I 7 What is the difference between them?

 Now nearly all desktop and laptop includes Intel's Core i-3, 5, 7 of the processor. Core i-3, 5, 7 in the desktop and mobile processors (for laptops). We know that many of them do not know about most of them, but there are many wrong ideas about this process, so I'll talk about the differences.

** The existing processor clock speed, cache size, and hyper-threading technology turbo-boost the ratings and the number has been estimated.

** Some may think that the core of the 7 seven core of the 5 five core and three-core Core 3, it has meant the numbers for their processing power.

** Existing Intel processors, has been identified as the core of the star rating of 3 three-star, four-star 5 Core, and Core i-7 Five Star, and Celeron and other existing entry level processor is the star.

There are many differences between desktop and laptop processors 

Desktop processors:
If you want to know that the overlay performance forward, but the simple answer is, the core of the 7 most forward, Core, and Core i-3, then 5. Core i-7 processor core groups of four to six, four-core Core i-5 dual-core processor, and some are, and Core i-3 processors have dual cores are. There are many differences between the catches, as well as 3 of the 4 MB Core, Core i-5's in the 4-8 MB, and the core of the Seven's case is 8-12 MB cache memory.
Laptop processors: 
The Core Laptop Core 5 and Core i-3's than 7 forward. There are many models of the Core i-7 dual-cores (they are more used Ultra books groups). They are so much lower performance. It's closer to the core of the 5 and 3. 5 is a dual-core processor, the Core laptop, desktop and laptop processors are others that have approximately the same performance, But you need to know is that desktop processors are quad cores, (some models have dual cores) overlay performance desktop processor, so it has to continue. So if you think your ideas are wrong, but you can get a laptop with the same performance. The performance of the core is equal to 3, not only because they technologies turbo boost Core 3 was slightly ahead of, the performance is almost the same all over. It costs about the same.
