Quad-core vs Dual-core processor: What Is Best For Your PC? How they are different? Is quad core better than Dual-core for gaming? Quad-core vs Dual-core which is better in MacBook pro? How much faster is Quad-core vs Dual-core? Dual-core vs Quad-core i5? Yeah! in this post, we will cover all such topics related to processors.
Introduction: Quad-core vs Dual–core processor
Nowadays, possessing a PC or laptop is not a great deal. Everyone has one Laptop or at least wants one. Some buy laptops for their official use while some game lovers get gaming PCs for themselves to play Graphically Demanding PC Games. Even though everybody has their own computers, there are certain technical terms that are not understood properly.
I have seen many of my friends who know a few computer terms but don’t have a clear idea about every term they utter. Consider this example-Almost all PC users might have heard about these words Quad-core vs Dual-core processor or Hexa-core vs octa-core processor, but we still don’t have in-depth knowledge in it. We still get confused about the processor’s core. Even sometimes we compare dual-core or quad-core with that of intel i3,i5, and i7.
In reality, we cant compare Quad-core or dual with i3,i5, and i7 because they aren’t mutually exclusive. That is to say, Quad-core just means having four processing cores whereas i3,i5, and i7 are brands of Intel. They are named according to the advanced technology used in the manufacture of the chip. It’s just basically a name convention that they are okay with. For instance, you can have a Core i5 processor with dual CPU cores and another quad-core.
Anyway, this is only an example. In this post, we will try to understand more such terms and their functions in more detail. Before figuring out which is better between quad-core vs.dual-core processors, let’s start with some basic terms and concepts about computer processors, which can clear up the fog around the subject. This will not only help us to make our understanding more clear but will also help while going to buy a new PC.
What is a Processor in computers?
In simple words, the processor is an integrated electronic circuit that is placed in the motherboard to perform the calculations. These calculations helps to run a computer. A processor performs all arithmetical, logical, input/output and other basic instructions that are passed from an operating system (OS). Physically it is a separate chip or multiple circuit board that is responsible for the allocation of commands for other chips and components present in a CPU. It makes all the logical decisions, from opening a window to the most complex like completing a 3d animation.
To understand how it works imagine this scenario we have a processor, memory RAM, and inputs coming from the output devices like hard drive, mouse, keyboard, and monitor. The mode of communication between them is the motherboard. The motherboard is responsible for linking the processor to all the other components.
The processor executes three basic functions-
- receive input data
- process this data
- and provide output data
All this is done in a fraction of a seconds There are other types of processors too which may be installed on your system but every processor contains several important components. Some of the importanr ones are
The socket: The socket is a type of physical connection between the processor and the motherboard and it is responsible for transmitting energy to the processor
The clock: Clock is responsible for defining the frequency that the processor will use to execute one task. It is measured by a unit Hertz. To clarify, it is the number of cycles that can happen in a given amount of time in seconds . for example, if a processor has a two gigahertz clock it can have up to two billion cycles per second. So the higher your clock speed is the lower the execution time and faster processing power
The caches: Basically, the cache is the auxiliary memory of a processor where the most accessed data will be processed, identified, and then stored. The processor accesses this memory and is able to execute the action faster because it’s more readily available. This is one more important factor that has a direct impact on the processor speed. The more cache means more quick storage capacity and good speed.
The core: It is the brain or processing unit of the processsor.
What is a Core in Processor?
As I said before it is the processing unit (brain)of the Processor that handles all the data for your device. The cores are responsible for the processing speed. It receives directions and performs calculations or operations to fulfill those directions. The more cores a processor has, the more functions it can execute simultaneously without overloading our system. A core can work on one task, while another core works a different task. A Core is named Dual-core, Quad-Core, Hexa-core, Octa-core, and Deca-core according to the number of cores placed in a processor chip. So, A processor with two cores is called a dual-core processor; with four cores, a quad-core; six cores, Hexa-core; eight cores, octa-core.
What are Single-core and Multi-Core processors?
Let me explain to you what is basically a single-core, multi-core, or whatever dual-core,quad-core, six-core,eight-core processor or something is?
Basically, let’s think a the single-core processor as one hand. If you have one hand that’s a single core now. And If my the processor was a dual-core I’ll have two hands. Similarly, if I have a quad-core the processor I’ll be having four hands and so on.
So your general conclusion would be that more hands I will have, faster the task I can complete. You are actually right but it’s not entirely true. Let’s consider an example, I have one scissor and I have to cut one thread, now this task is ideal for just one process that too by one hand. If let’s say all of my four hands would start cutting that thread it’s not going to make any sense at all. So basically this task was ideal for just one processor
Now let’s say we have this another task where we need to pack 300 smartphones, packing each smartphone in each box. Now this task can easily be divided among all the 4 hands and we may even work faster. And the same happens with the core too.
Single-core CPUs are designed with one core to process all data. A single-core processor will do only one task at a time. The single-core processor will slow down the process of storage, order, execution, and retrieval of instructions. If multiple applications are run at the same time, the computer speed will decrease.
A multi-core processor is a CPU with the core logic of two or more processors on the same single physical processor chip, each with its own cache. This is equivalent to two microprocessors in one single unit. So Dual-core, Quad-Core, Hexa-core, Octa-core, etc are the multi-core processors. The multi-core processor can perform multiple tasks at the same time and increase the overall performance of co-processing console programs
For day-to-day apps, multi-core performance is more useful. However you do not need a multi-core processor to run multiple applications, even multitasking can be served by single-core processors. But power consumption is more in single-cores as compared to multi-core processors. It will use its entire high frequency to provide the desired output. Ultimately your laptop has to sacrifice much of its power to run the processor.
For nowadays you definitely need a multi-core based processor. As applications are getting more flexible and advanced, this requires much more power and battery optimization for the smooth running of the CPU
Quad-Core vs Dual-core: Which is better? Quad-core vs dual-core MacBook pro
As we already know that dual-core and quad-core are multi-core processors, they have been also prefixed as duo and quad according to the number of cores present in a unit. It pronounced as dual-core and quad-core because dual-core means two cores processing for the one information simultaneously and quad-cores are basically four cores processing for the same information.
What I’m trying to explain is that basically the efficiency of dual-core vs a quad-core processor differs from task to task. Generally, it is ideal to have at least a dual-core processor. Its because the dual-core processor is going to deliver a really great general experience for most basic users. If you’re using your PC just for checking your email, browsing the internet, listening to music, watching movies, those are all simple tasks that a dual-core processor can handle very well
Again for professional users who deal with very specialized applications or heavy software like video editing, Animations, Sound mixing, or gaming, a quad-core processor is more than enough.
Quad-core vs dual-core macbook pro
As I have already explained which is better between quad-core vs dual-core. The same answer is applied to Mac Pro too.The dual core Mac is optimal for daily works like Internet browsing and other office works (datasheet, word processing, PowerPoint presentation etc).However the quad core is much better for heavy tasks such as video editing, 3D rendering and has a particularly superior multitasking performance.
Note 1.Quad-core processors generate more heat than dual-core chips, as each core emits its own heat. When quad-core processors are fitted, you usually have to set a better cooling fan in your system
Note 2. Power consumption in quad-core laptops is comparatively higher than dual-core computers. So you can see good battery life in quad-core running PCs
Price vs performance: Dual-core vs Quad-Core
It is important to strike the right balance between price and performance. As I said before, you should not go for quad-core if you are a basic PC user. You should also consider the price factor And it is obvious that the quad-core processor will cost you higher than dual-core processors. So Quad-core only will be a worthwhile investment. if you want to use your computer for professional use. Also, it should be kept in mind that Double the Cores does not always mean Double the Speed.
Suppose you got a PC with a dual-core processor and you are using this PC to surf on Google. Let us assume that you have installed a good antivirus on your PC. While surfing on the internet, antivirus scanning has stated in the background. So if you’re having a dual-core process what will happen is that one core will be assigned to whatever task you are doing that is surfing the internet and the second core can be used to do the antivirus scan in the background.
Now moving to quad-core basically depends upon the type of application you use. It is because not every application can take advantage of all the four cores. Although it is not bad to have four four-core processors, you have to also consider whether all the cores are being utilized effectively or not.
Generally what happens is that the software or whatever game which is not optimized for a quad-core or whatever only the two-course or one core will be working and the other two cores will be staying idle. So it is not mandatory to just go for a quad-core or a higher core processor so if you are doing a simple task or dual-core processor is more than enough
Nevertheless, if you’re working on some heavy applications like Photoshop, video editing apps, animation software or even playing games then a quad-core processor will be helpful for you. Some of the latest games are designed with several elements. And these types of games can utilize all the four cores of the processor at a time. Suppose you are playing a fully graphics loaded game on a quad-core PC. Then, One core can be assigned for the artificial intelligence of the game, the second core can be assigned for basic physics of the game and the other two cores can run the main game engine
In short, if you are a heavy gamer and you are trying to build a new system then you can go for the quad-core, six-core, or eight-core processor. Also, these multi-core processors are ideal for people who are heavily involved in tasks like media production, sound editing or video editing, animation, graphic design, etc. So choose between Dual-cores vs. Quad-cores wisely by considering your needs and PC usage
1.Casual Computing: Dual-Core Processors
2.Mainstream Computing, Programming, Gaming: Quad-Core Processors
3.CPU Intensive Games, Full-stack Application Development,4K Editing and Rendering, Live Streaming and Gaming Simultaneously: Higher multicore processors like Hexa-core,octa-core or deca-core
How to check what Cores Does My Computer Have?
For Windows users – To check the number of cores and Base speed of the CPU you have to open Task Manager. To visit Task Manager move your mouse pointer to Taskbar. Right-click on the taskbar and click on Task Manager. Then select a Performance to know every detail of the processor and cores. You can also open task manager directly by pressing Ctrl + Alt + Delete key + Esc button simultaneously
For Mac users – It is not so simple to find the number of cores of the Mac OS, but you can check what kind of processor your PC has. For this, you have to click on the Apple logo in the top right-hand corner and click the About This Mac tab. This will tell you the processor information and you can use this info to find out more details using Google
What is Hyperthreading in processors?
Normally one thread runs on one core only. But Hyper-threading is a hardware innovation where two threads are able to run on one single core. It allows a single processor to act as a dual processor. This technology allows two threads to be processed in a single processor core allowing partially parallel execution whereas traditional single-threaded processors could only process one thread at a time. For example, if your laptop is having two cores, then by enabling hyperthreading this 2 core will act as a quad-core processor.
Under the right circumstances, this technology by Intel allows the CPU core to do two things effectively and simultaneously
What is thread and how it is different from core?
Let’s try to understand Thread in simple language. Each core process only that information or perform tasks what the operating system tells them to do. So the OS or the operating system is kind of like the boss and each core is a worker. On the other hand, threads are kind of sequences of commands given to the cores.
So you can think of threads as conveyor belts of products being sent to the worker(core). Now we have understood the general purpose of threads and cores. Butt It’s also important for you to know the difference between what a physical core is and what a logical core.
Logical core vs Physical core
A physical core is a kind of what it sounds like it’s physically on the CPU. A logical core is more like code it exists on the computer and we can also call it a thread. So, for example, if you have a processor with 4 cores and 4 threads, you can say the processor has 4 logical cores and also have 4 physical cores. And you should not count 4 cores and 4threads as a total of 8
Now if you have a processor with 4 cores and 8 threads, well then if you were asked how many logical cores you have you could say 8 logical cores but you still only have 4 physical ones. So logical cores are basically the different amount of pathways that you can see or that your computer has to process information. In common words, there are eight ways for logic or information to get processed through your computer.
In the case of two threads per core, each core can take on two different threads of commands. Now for a single core, if it gets two threads to work then during normal operation won’t see continuous execution on a single thread.
How to enable Hyper-Threading?
Most of the dual-core and quad-core come with pre-enabled Hyper-threading technology(by default). But you can turn it on and off from the BIOS environment to “enable” or “disable” “hyper-threading technology”. Note that Intel® Hyper-Threading technology is only available on some enthusiast CPUs: see the full list here.

When is Hyper-Threading best applied?
Hyper-threading technology comes to the best use in those situations where customers don’t want to go for a higher core number but want the lag-free or smooth performance of his PC. Applications demanding high CPU usage like -video editing, 3D rendering, and heavy multitasking, Playing games with the live stream, basic level animations, etc
On the other hand, operations where tasks have to be performed in serial, or where one operation has to be done before starting another, usually do not benefit from hyperthreading.

What is Intel Turbo Boost?
Suppose your processor has a base clock of 3.5 GHz. So whether you are watching a video or just browsing the web, even doing nothing on your computer, it will only run at 3.5 GHz. But when it starts to get a bit stressed or has a heavy workload, it needs to get more power and more power is needed to maintain it. Intel Turbo Boost is a technology that automatically makes the processor core to run faster than the marked frequency if power usage and temperatures are within limits.
When you are playing a heavy game, editing or exporting videos, 3D rendering, etc. and for such things, the CPU uses turbo-boost technology. Turbo Boost overclocks its CPU to increase its clock speed and allows it to actually accelerate to higher GHz.
How to Assign specific CPU cores to programs?
You can also assign individual CPU cores to the programs. To do this, open the “Details” tab in the task manager. Select the program you want to assign cores. Right-click on the corresponding program and select “set affinity“. After opening the Set affinity tab, uncheck the CPU that you don’t want to use. This is useful if computationally intensive programs slow down other applications. By default, Windows distributes the computational tasks equally among all cores. Even for games that are designed for less than the available cores, it is a good idea to limit the use of the cores
How to Limit the number of cores?
You can also set Windows to use only a certain number of processors. To do this, click on the search button and type “MSConfig” to open the “System Configuration“. Under the “Start” tab, select “Advanced Options…”. Then you can specify how many cores Windows should use. The changes will take effect as soon as the system is restarted.
Windows uses all of your computer’s processor cores by default. Therefore, changing the number of processors in the System Configuration utility will not increase your computer’s performance during startup or while Windows runs
