This article lists the difference between Desktop and Mobile CPUs. A central processing unit (CPU), also known as a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program.

In simple terms, a CPU is responsible for how fast an application opens on your phone, how smooth your apps run without your phone freezing, etc. A Desktop’s CPU (for example Intel’s Processors) is different from a mobile phone CPUs (for example Qualcomm’s Snapdragon Chips). Usually, desktops handle more multi-tasking than phones. By multitasking I mean you can open several windows at the same time as you switch between tasks smoothly. Desktops do this more efficiently than on phone. Some phones do not keep the last state they were in before the app was left.

Difference between Desktop and Mobile CPUs:

  1. Desktops usually have a higher processing speed and better cache than a mobile CPU that typically have a reduced speed.
  2. Because of their higher number of cores, computers with Desktop CPUs are normally more powerful but generate more heat than CPUs powered by mobile processors.
  3. Mobile CPUs work with RISC which means it is capable of executing fewer and simple instructions. On the other hand, the desktop CPU works with CISC which means it is efficient in executing very much and complex instructions.
  4. The architecture of mobile CPU is based on the ARM(Advanced RISC Machine) while the architecture of Desktop or computer CPU based on x86 or x64.
  5. Mobile CPUs consume less power while the desktop CPUs consume more power.
  6. The mobile CPU is smaller in size whereas the desktop CPU is larger in size.
  7. Mobile phone CPUs have more general purpose registers inside them than the desktop CPUs.
  8. Modern desktop processors have Cache Memory inside them. The present mobile processors do not have any cache memory inside them.

Those are some of the differences between the CPUs for Desktops and Mobile Phones.
