What are the differences between hexa core and octa core processor? In simple mathematical terms, octa-core processors are those that come with 8 cores and hexa-core processors are those processors that have 6 cores in them.

Ideally, these processors are suitable for multitasking due to the larger number of cores.

Each of the cores in a multi core processor, whether it is quad core, hexa-core or octa core processor, is dedicated to do different tasks.

It is this division of workload that makes the processors work much more efficiently as compared to other processors that do not have multi-core features.

This means that in a multi-core processor the cores will perform differently such as:

  • One core of the processor may be operating your call
  • Another doing the needful to open a website
  • A third one helping you in playing games or listening to music and so on.

All these jobs done at the same time will make your computer system work more efficiently.

However, this does not mean a single core of the multi-core processor will be dedicated to perform a particular task only.

Typically, the main reason to have multiple cores in a processor is to distribute the workload among the cores so that the computer system, on the whole, can function more smoothly. There will be no interruptions or freezes.

Modern octa core processors have two sets of four cores each. One set is of low power while the other is of high power. All these cores are, however, independent. The tasks, according to its type, are split between these two cores.

In most of the cases, it is the low powered set of cores that will perform the necessary tasks. However, when you need to do some advanced tasks, such as rendering or watching HD videos, the high-power set of cores will be employed as well.

On the other hand, hexa-core processors also belong to the multi-core processor family. This has six different cores but this does not mean it has six different Central Processing Units.

This may perform at a speed that is much higher than a dual or a quad core processor. For example, the AMD Phenom II X6 is a six-core processor that can perform within a speed range of 2.6 to 3.8 GHz.

Which processor is better in performance? Well, that will depend on several other factors and not only on the number of cores available in the processors. To know this, you will need to know about the difference between a six-core and an octa core processor.

Ideally, you will not be able to tell the difference between the two processors simply by the number of cores it has. There are several other things to consider for that matter to judge the performance level of any processor. These include:

  • The core designing
  • The volume of silicon used in making it
  • The fabrication processes
  • The types of transistors used
  • The clock speeds
  • The cache memory and more.

When you consider all these factors you will know that there is a significant difference between what is on paper and in the performance of a processor in real life. Check out differences between Octa Core and Quad Core processor.

Differences Between Hexa Core and Octa Core Processor

Differences between Hexa Core and Octa Core Processor

1. Design and Architecture

A hexa-core processor will come with 6 cores that may function independently or together as per the need.

However, if it is of a dual + quad-core variant, there can be two performance cores and four power efficient cores. Depending on the make and model of the processor, it may help in neural processing as well.

An octa core processor will have 8 cores. If it has a dual-hexa-core architecture there will be 2 performance cores and 6 efficiency cores.

Alternately, if it has a quad-quad architecture then it will have 4 performance cores and 4 efficiency cores. This indicates that a quad-quad architecture will be much better in performance.

2. Increasing the Speed  

The hexa-core processors can ensure a faster performance because this is a bionic chip that uses a larger cache memory.

The octa core processors can however increase the performance speed by using a large number of transistors.

3. Use of Silicon

In an octa core processor the performance can be enhanced by using a large amount of silicon. However, that will increase its cost.

On the other hand, a hexa-core processor will not be such a costly upgrade because the silicon amount used in it will be far less.

4. Superior GPU

Though both the processors are capable but a hexa-core processor is much faster than an octa core processor because of its superior GPU.

The octa core processor lacks this as of now, but specific manufacturers are now focusing on creating custom architecture to increase the performance and benchmarking results.

Which is Better – Octa Core or Hexa Core Processor?

There is nothing called a better processor. Ideally, a quad core processor may even beat a six core or octa core processor.

This is because the number of cores simply indicates how fast the task will be completed.

Obviously, larger the number of cores, faster will be the job done. This means, usually, an octa core processor will be faster than a hexa-core processor if it belongs to the same family and generation of processors.

Based on this principle, it can be said that an octa core processor will be much better than a hexa-core processor in terms of speed only but the same may not be said sternly about its performance.

This is because you will need to take the processing power of these processors into account to determine the level of performance. This is more important factor than the number of cores.

Another important factor to consider is the clock speed of the two processors. Typically, an octa core processor will have a lower clock speed as compared to a quad core or a hexa-core processor.

If the architecture of the two processors are the same, then the clock speed will be a vital deciding factor.

Cost can also be an important factor for a few users to decide for or against such an upgrade depending on their budget.

Ideally, a hexa-core processor will give you some peace of mind if you are looking to future proof your computer. It will have the power and potential to meet your future needs without you needing to pay a premium for an octa core processor.

These are cheaper than the 8 core counterparts. Nevertheless, these hexa-core processors can deliver the desired performance for high-end tasks and intense gaming, whether it is a CPU intensive game or that of the MMO or Massively Multiplayer Online genre.

However, the hexa-core processors come with or without multithreading ability. Therefore, if you want the processor to do complex tasks simultaneously then an octa core processor will be a much better choice. These tasks may include:

  • 4K editing
  • Rendering
  • Gaming and
  • Streaming HD videos

An octa core processor is the premium offering in the desktop segment that comes in both multithreaded and non-multithreaded variants.

These chips are designed to run intensive apps and provide the best to the users. However, these chips can come with a price tag that is equivalent to a new laptop or desktop computer of entry level.

Finally, there is one more thing to consider. There are hardly any games available as of now that will need to use the 8 cores of a processor.

Therefore, there will not be any significant change in the efficiency. In fact, there is a high possibility that playing such high-end games on an octa core processor can be an overkill.

In a Nutshell

Now that you know that there are lots of differences among hexa-core and octa core processors in terms of CPU clock speeds, manufacturing process, and CPU architecture, you should choose a processor wisely.

It is best to choose a processor that will serve your purpose and suit all your varied requirements.
