What's the difference between an Intel Core i3, i5 and i7 ?

Difference ( Core i3 , Core i5 & Core i7)


Intel Core i3 Processor

This particular Intel processor is the enter level processor of this new series of Intel processors. While it may not be the fastest one of the bunch, it can get the job done, at least for most applications.
Mind you, if you need high speed, I suggest one of the other processors that I will unveil in front of your eyes later on in this post. Here’s some of the Core i3 features.
  • Uses 4 threads. Yes, it uses hyper-threading technology which is the latest craze due to its improved efficiency over earlier processors that were put on the market.
  • This processor consists of 2-4 cores, depending on which one you get your hands on.
  • Contains A 3-4 MB Cache
  • Uses less heat and energy than earlier processors, which is always a good thing in this day and age.

Intel Core i5 Processor

  • This is the mid-size processor of this bunch, recommended for those who demand a little speed, but not quite enough where the user will be running resource-intensive applications.
  • As with the Core i3 processor, this comes with 2-4 cores, the main difference is that it has a higher clock speed than the Core i3.
  • This is also a heat and energy efficient processor, but it does seem to be better at this particular job than the Core i3 processor.
  • The number of threads used in this is no different than the Core i3 with 2-4 threads, and it also uses hyper threading technology for a boost in performance.
  • The cache of the Core i5 is bigger than the Core i3, it’s at 3-8 MB.
  • The Core i5 is where the turbo mode is made available, this provides users with the opportunity to turn off a core if it’s not being utilized.

Intel Core i7 Processor

  • This is for the users that demand power, yes it does provide more power and if Tim Allen gets one of these, this would be the beast that he gets his hands on. Great for gamers and other resource intensive users. 
  • The cache on this one is 4-8 MB.
  • This processor comes with 8 threads, definitely enough to get the job done quickly, maybe even at the speed of light if you’re lucky.  And yes it also utilizes hyperthreading technology.
  • You will have four cores to take advantage of with this particular series.
  • And just like the other ones in this Intel series of processors, it is more energy efficient and produces less heat.
