What is the difference between Core i3, i5, i7 and i9 processors ?

This is general question comes to your mind when you buy a new laptop or build your own computer. it is important to select the right processor that gives you the best performance, excellent speed in your budgets. remember one thing processor is the main part of pc or laptop. so that why it’s important to select right processor. processors i3 i5 i7 i9it’s important to select the latest generation processors for better performance each time the i3, i5, i7, and i9 are updated. the new update is known as 8th generation and the last update was known as the 7th generation. it’s important to select the latest generation processors for better performance. here we compare some functionality that Intel’s processor has.

Intel Core i3 :

i3_processorthis processor easily available at cheap price. core i3 processor is fine for day to day use. this processor perfects for those people who do not need to use high graphics video editing software or heavyweight game. 

  • No. of core: 2
  • Turbo Boost: No
  • Hyper-Threading: Yes
  • Cache Memory: 3 – 4MB

Intel Core i5 :

i5_processors

it is little more expensive than i3 but cheaper than i7. core i5 processor is for Intermediate users. this processor is best for those people who use high graphics photo editing software or heavy game. 

  • No. of core: 4
  • Turbo Boost: Yes
  • Hyper-Threading: No
  • Cache Memory: 4 – 6MB

Intel Core i7 :

i7_processors

it is more expensive than i5. core i7 processor is for users who need the high performance like video editing on daily basis. this processor perfects for those people who do need to use high graphics video editing software or lag-free gaming daily. 

  • No. of core: 4
  • Turbo Boost: Yes
  • Hyper-Threading: Yes
  • Cache Memory:  8MB

Intel Core i9 :

i9_processors

it is more expensive than all other processors. core i9 processor is for users who need the high-performance pc or laptop. these processors for few people who need to use high graphics work daily basis. 

  • No. of core: 10
  • Turbo Boost: Yes
  • Hyper-Threading: Yes
  • Cache Memory:  14 – 16 MB

terms that I use above use…

The number of cores :

only one thread can be served by one core at a time. the more numbers of cores mean more threads can run at same time. the dual-core processor has two internal processors, a quad-core processor has four. More cores are useful in multi-tasking. for example, you can run two applications at the same time, each one having access to its own dedicated processor.

Turbo Boost :

Clock speed is reasons behind why cheap i3 runs at a faster speed than the Core i5, i7, and i9.then first we see about clock speed.

clock speed: the speed of a microprocessor, expressed in cycles per second in gigahertz (GHz). remember that thing, the bigger number means the faster processor.

for example : 2.3GHz means 2,300,000,000 clock cycles.

  • i3 Clock Speed: 3.4GHz – 4.2GHz
  • i5 Clock Speed: 2.4GHz – 3.8GHz
  • i7 Clock Speed: 2.9GHz – 4.2GHz
  • i9 Clock Speed: 2.6GHz – 4.4GHz

The Intel Turbo Boost Technology is technology that allows a processor to increase its core clock speed dynamically whenever the need to arise. Turbo Boost dynamically increases the clock speed of Core i5, i7, and i9 processors when more power is required. A processor can use only Turbo Boost for a small amount of time. This means that the chip can use less power, produce less heat and only boost when it needs to. For example, the Core i5 chip can boost up to 3.8 GHz when required, so will end up being quicker. A processor can only Turbo Boost for a limited amount of time.

Hyper-Threading :

Only one thread can runs on one core at a time. for that, if CPU is dual-core processor then only two threads can run simultaneously…for solving this problem Hyper-Threading is used. Hyper-Threading is a technology used by Intel microprocessor that allows a single core to act like two different core. Hyper-Threading divides one physical core into two logical cores. That allowing the processor to run double the amount at the same time. So a 2 core processor will work like a 4 core processor and a 4 core processor will work as an 8 core processor.

Cache size :

Whenever the CPU finds data that use over and over then, it stores that data in its cache. Cache is just like RAM, it is faster because it is inside into the CPU itself. Both RAM and cache holding frequently used data. Without them, the CPU would have to keep on reading from the hard disk drive, which takes a more time. Basically, RAM minimizes interaction with the hard disk, while cache minimizes interaction with the RAM. This is clearly one reason why an i9 faster than i7, i5 and i3.
