I love Intel products because they make cool products they engage in a lot of community stuff. But when it comes to confusing people with models! What the heck is Core i7? What is 1st, 2nd ,7th generation?

Core I processors Explained

Core i3 supports Dual core while both core i5 and core i7 support Quad Core. What does quad means in processor?

Cores in processor

Each core acts as a single processor. Dual core processor, therefore is having two internal processors. Same in quad core it has 4 internal processors in it. More cores are useful for multi-tasking; for example, you can run two applications at the same time each one having access to its own dedicated processor. More cores are also important for muti-threading application, such as video editing and graphics designing.

Hyper threading technology

Hyper threading is a technology which allows a single processor to act as two logical different proccessor. In terms of performance, Hyper threading speeds up the multi-tasking and muti-threaded application. It’s not as fast or as efficient as extra ‘real’ cores, but it’s an improvement over a single core.

Turbo Boost

Intel’s turbo Boost technology allows processors for automatic overclocking and boosting its clock speed higher than the default settings. The CPU monitors its temperature and, when it’s running cool enough, it will apply overclock

Clock speed

The faster the clock speed in GHZ, the faster each core can run. For example, a Core i3-4370 Hanswell processor runs at 3.8 GHz and Core i5-4590 runs at a clock speed of only 3.2GHz. In this case Core i3 would be faster in running a single threaded application. However, in a case of running a multi-threaded application, the Core i5 would most likely be quicker, as it is a quad core processor and has four real core in it.

 

Features Core i3 Core i5 Core i7
Number of Cores Dual Core Quad Core Quad Core
Hyper Threading Yes No Yes
Turbo Boost No Yes Yes
Max Clock speed 3.8 GHz 3.5 GHz 4.0 GHz
Maximum Cache Mem 4 MB 6 MB 8 MB

 

 

Generations Explained

The last time when I went to a computer shop to buy a laptop the seller told me that this laptop is having fourth generation of intel processor. I asked him, what is the difference between 1st generation and 4th generation of processor. His just told me that the 4th generation is faster than subsequent generations of processor. Is this the only difference between first generation and 4th generation?

Let’s find out:

Processors size is measured in nm. Nm stands for Nano meter. It is the size of a transistor in processor. The smaller the transistor, the more transistors that can be fixed in a processor. For example, 42nm transistor will occupy more space in a processor compared to 14nm transistors. In simple language, the smallest transistor will give you better performance. Therefor always go with the latest generation of processor.

Processor Generation Processor Code Name Nano meter(nm) Processor Graphics
1st Nehalem 42 nm Intel HD Graphics
2nd Sandy Bridge 32 nm Intel HD 3000
3rd Invy Bridge 22 nm Intel HD 4000
4th Haswell 22 nm Intel HD 4600
5th Broadwell 14 nm Intel iris Pro 6200
6th Sky Lake 14 nm Intel HD Graphics 530
7th Kaby Lake 14 nm Intel HD Graphics 620

 

With this, Intel also improve its Graphics quality in each generation. As for example in 6th generation processor, you are able to play almost all the new PC Games at medium settings. So, if you are looking for a PC for playing games in medium settings always go with the latest generation of processor.

Recommendation:

Core i3

Bloggers and Webservers

Core i5

Software programmers & image/video editors

Core i7

Pc gamers & 3D rendering
