Q

Types of CPU

oldest type of computer CPU, which
was used in the 1970s. It has only one core to process different operations. It
can start only one operation at a time; the CPU switches back and forth
between different sets of data streams when more than one program runs.
So, it is not suitable for multitasking as the performance will be reduced if
more than one application runs. The performance of these CPUs is mainly
dependent on the clock speed. It is still used in various devices, such as
smartphones.

Q

Types of CPU

contains two cores in a single Integrated Circuit (IC). Although each core has its own controller and cache, they are linked together to work as a single unit and thus can perform faster than the single-core processors and can handle multitasking more efficiently than Single Core processors.

Q

Types of CPU

uses a technology that allows four independent processing units (cores) to run in parallel on a single chip. Thus by integrating multiple cores in a single CPU, higher performance can be generated without boosting the clock speed. However, the performance increases only when the computer’s software supports multiprocessing. The software which supports multiprocessing divides the processing load between multiple processors instead of using one processor at a time.
