5 Advantages and Disadvantages of Multi core Processor | Drawbacks & Benefits of Multi core Processor

 

Multi-Core Processor: What is it?

A chip with two or more processors on it is called a multi-core processor. Every processor has the capacity to handle multiple tasks at once. For instance, if one CPU is tasked with processing data, the other will handle data storage.

Why do we use Multi-Core Processors?

The configuration resembles that of a dual-core CPU. Different types of multi-core processors exist, based on the quantity and sort of cores. To achieve good performance, multi-core processors are used. It was introduced to get around the physical constraints of a CPU with one core.

While using a multi-core CPU has numerous advantages, there are also certain risks involved. The benefits and drawbacks listed below will assist you in making a decision if you aren't sure you should upgrade to a multi-core processor.

You will learn about the 5 Advantages and Disadvantages of Multi core Processor | Drawbacks & Benefits of Multi core Processor in this article. You will learn about the pros and cons of using a multi-core CPU from this page.


Now let's get started,

 

Advantages of Multiple Core Processor

1. Performance

A multi-core CPU by default facilitates more productivity than a single-core processor. Higher clock rates are possible when the cores on an integrated chip are positioned apart. 

 

As a result, the signals are durable and do not require a long distance to reach their destination. When compared to a separate processor, the speeds are noticeably higher.


2. Reliability

Software runs on separate cores on multicore processors at all times. If there are errors in one piece of software, it won't affect the other. 

 

A single core is the only area where defects can occur. As a result, multi-core CPUs have a higher fault tolerance.


3. Software Interactions

Software running on separate cores will nevertheless communicate with each other. Spatial and temporal isolation is a process that a multi-core processor goes through. 

 

These procedures guarantee that there is never a delay in core threads.


4. Multitasking

An operating system can run two or more tasks concurrently on a multi-core CPU. even if using the same application to complete tasks at the same time is possible. 

 

A Photoshop application, for instance, can be used to two tasks at once.


5. Power Consumption

Utilizing a multi-core CPU to perform multitasking essentially uses less power. The processor's portion alone will be producing heat. 

 

Over time, there is a decrease in power consumption, which lowers the amount of battery used. Still, some operating systems use more resources than others. 

 

Disadvantages of Multi Core Processor

1. Application Speed

While multicore processors are meant to be multitasking machines, their speed isn't really that important. 

 

An application has a tendency to switch between cores while it is processing. Consequently, the cache fills up to match its speed.


2. Jitter

A multicore processor with more cores will have more interferences, which will result in excessive jitters. 

 

This could lead to regular failures and a decline in program performance on your operating system. 

 

The user can only manage jitter by employing a microkernel and full synchronization.


3. Analysis

It takes more memory models to accomplish two or more jobs at once. This makes using a multi-core processor for analysis challenging. In particular, timing limits are difficult to measure and may not be precise.

Furthermore, the interference analysis may become more difficult as the number of cores rises. As a result, the O/S won't be able to perform as planned.


4. Resource Sharing

A multicore processor shares various resources, both internal and external. Main memory, the system bus, the memory controller, and networks are some of these resources. 

 

As a result, any program running on the same core will likely experience interference. Interference of this kind may be isolated in terms of time or space.


5. Software Interference

Spatial and temporal isolation may be hampered by software interference brought on by resource sharing. If there are additional cores, the likelihood increases even further. 

 

In essence, having more cores indicates having a large number of interference routes. Analyzing every possible interference path is nearly impossible.
