Should you purchase a computer with an x86 processor, an Intel Atom processor, or an ARM processor? What are the pros and cons of each type of processor? Will you want a multicore processor? Why or why not?

Here is a tip:

It is used mostly in electronic devices such as tablets and mobiles.


  • It is of very low cost, energy efficient and requires less power than other processors.
  • Although its process is a bit slow when compared to x86 processors, it has more efficiency than x86.
  • The expandability of the processor is more than the others.
  • As chips are integrated in a small space, the size of the processor is also small and easy to use.
  • This is why almost all mobile phones and tablets are coming up with this processor.

Verified Answer

Intel Atom, as it consumes very less power and heat when compared to the others.

Intel atom:

  1. Pros: Low cost, low power consumption, low TDP, expandable
    Cons: Its performance in 3D is very poor and the chipsets are integrated.
  2. X86 processor:
    Pros: System configuration, more powerful performance
    Cons: More heat and power used, it compromises the system easily
  3. Arm processor:
    Pros: Less consumption, ideal for embedded devices
    Cons: Its capacity to calculate is very low, not expandable
