Computers and their parts are filled with millions of jargon’s and specs making it difficult to understand them and find the right device for the right job. Let us shed some light into understanding the specifications of the core component of your computer – “the processor alias CPU

The number of bits 32 bit vs 64 bit:
If you have not studied computer architecture this is definitely confusing for you. When you walk into buy a CPU the vendor will say that 64 bit is better than 32 bit, but you notice its costlier and you are unsure if you need it. Let us understand that by going for higher number of bits we have following advantages:

  • More bits means that data can be processed in larger chunks which also means more accurately.
  • More bits means our system can point to or address a larger number of locations in physical memory.

You should  actually buy a 64 bit CPU.

Do I need an i3, i5, or i7?

First understand difference among these processor.

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 hyperthreading 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 hyperthreading 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.
