What Do “Dual Core” and “Quad Core” Mean?

Mihir Patkar Updated 15-12-2019

When you are purchasing a new laptop or building a computer, the processor is the most important decision. But there’s a lot of jargon, especially the cores. Do you need a dual core, a quad core, a hexa core, an octo core…


Let’s cut the jargon and understand what it all really means.

Dual Core vs. Quad Core, Explained

Here’s everything you need to know:

This article deals with dual core vs. quad core processors for computers, not for smartphones. We have a separate post on understanding smartphone cores Is an Octa-Core Better than a Quad-Core? Not Always! Android Processors Explained More cores don't necessarily mean a faster processor. Read More .

How Speed Is Affected by Dual- and Quad-Core CPUs

You might think more cores will make your processor faster overall, but that’s not always the case. It’s a little more complicated than that.

More cores are faster only if a program can split its tasks between the cores. Not all programs are developed to split tasks between cores. More on this later.


The clock speed of each core also is a crucial factor in speed, as is the architecture. A newer dual core CPU with a higher clock speed will often outperform an older quad core CPU with a lower clock speed.

Power Consumption

More cores also lead to higher power consumption by the processor. When the processor is switched on, it supplies power to all the cores, not just one at a time.

Chip makers have been trying to reduce power consumption and make processors more energy efficient. But as a general rule of thumb, a quad core processor will draw more power from your laptop (and thus make it run out of battery faster).

More Cores Equal More Heat

More factors than the core affect the heat generated by a processor. But again, as a general rule, more cores leads to more heat.


Due to this additional heat, manufacturers need to add better heat sinks or other cooling solutions.

Are Quad Core CPUs More Expensive Than Dual Core?

More cores isn’t always a higher price. Like we said earlier, clock speed, architecture versions, and other considerations come into play.

But if all other factors are the same, then more cores will fetch a higher price.

It’s All About the Software

Here’s the dirty little secret that chip manufacturers don’t want you to know. It’s not about how many cores you are running, it’s about what software you are running on them.


Programs have to be specifically developed to take advantage of multiple processors. Such “multi-threaded software” isn’t as common as you might think.

Importantly, even if it’s a multi-threaded program, it’s also about what it is used for. For example, the Google Chrome web browser supports multiple processes, as does video editing software Adobe Premier Pro.

Adobe Premier Pro instructs different cores to work on different aspects of your edit. Considering the many layers involved in video editing, this makes sense, as each core can work on a separate task.

Similarly, Google Chrome instructs different cores to work on different tabs. But herein lies the problem. Once you open a web page in a tab, it is usually static after that. There is no further processing work needed; the rest of the work is about storing the page in the RAM. Which means even though the core can be used for a background tab, there is no need for it.


This Google Chrome example is an illustration of how even multi-threaded software might not give you much of a real-world performance boost.

Double the Cores Is Not Double the Speed

Dual Core vs. Quad Core - double the cores is not double the speed

So let’s say you have the right software and all your other hardware is the same. Would a quad core processor then be twice as fast as a dual core processor? Nope.

Increasing cores does not address the software problem of scaling. Scaling to cores is the theoretical ability of any software to assign the right tasks to the right cores, so each core is computing at its optimal speed. That’s not what happens in reality. In reality, tasks are split sequentially (which most multi-threaded software does) or randomly.

For example, let’s say you have a quad-core processor (Core1, Core2, Core3, Core4). You need to accomplish three tasks (T1, T2, T3) to finish an action, and you have five actions (A1, A2, A3, A4, A5) like this.

Here’s how the software will divide tasks:

  • Core1 = A1T1
  • Core2 = A1T2
  • Core3 = A1T3
  • Core4 = A2T1

The software is not smart though. If A1T3 is the hardest and longest task, the software have should split A1T3 between Core3 and Core4. But now, even after Core1 and Core2 finish their tasks, they have to wait for the slower Core3’s task to complete the action.

All of this is a roundabout way of saying that software, as it stands today, isn’t optimized to take full advantage of multiple cores. And doubling the cores does not equal doubling the speeds.

Where Do More Cores Really Help?

Now that you know what cores do and their restrictions in boosting performance, you must be asking yourself, “Do I need more cores?” Well, it depends on what you plan to do with them.

Dual Core and Quad Core in Gaming

If you fancy yourself to be a gamer, then get more cores on a gaming PC How to Build an 8-Core Gaming PC from Cheap Server Parts Want a beefed-up gaming or video-editing PC with dual Intel Xeon processors for under $200? The parts are out there, but finding and putting them together could prove difficult. Read More . The vast majority of new AAA titles (i.e. popular games from big studios) support multi-threaded architecture. Video games are still largely dependent on the graphics card to look good, but a multi-core processor helps too.

Editing Videos or Audio

For any professional who works with video or audio programs, more cores will be beneficial. Most of the popular audio and video editing tools take advantage of multi-threaded processing.

Photoshop and Design

If you’re a designer, then a higher clock speed and more processor cache 5 Little-Known Specs That Could Be Slowing Down Your PC We'll take a look at five lesser known factors that affect your computer's performance, and show you how you can always get maximum bang for your buck when upgrading. Read More will increase speeds better than more cores. Even the most popular design software, Adobe Photoshop, largely supports single threaded or lightly threaded processes. Multiple cores isn’t going to be a significant boost with this.

Should You Get More Cores?

Overall, a quad core processor is going to perform faster than a dual core processor for general computing. Each program you open will work on its own core, so if the tasks are shared, the speeds are better. If you use a lot of programs simultaneously, switch between them often, and assigning them their own tasks, then get a processor with more cores.

Just know this: overall system performance is one area where far too many factors come into play. Don’t expect a magical boost by changing one component like the processor.

    At some point Intel got off the speed bandwagon and now says cores is the key to performance. So give me more cores in my XPS 13 Dell but cut the base speed down to 1.6Ghz in order to handle heat. Sorry but turbo mode doesn't make up for that lower base speed. It just doesn't for most users, who would see better results with duel core at 2.5Ghz and a similar turbo speed. Like the author says not nearly enough apps that take advantage of multi core assignments to benefit for more cores.

    I'm using an old AMD Athlon X2 dual-core; a 2 GHz 3800+.

    'Ancient!', I hear you cry. 'It's a dinosaur...'

    By modern standards (and Windows usage), is. But I haven't run Windoze for years. I run Linux. And not just any Linux..... I run 32- and 64-bit versions of 'Puppy' Linux.

    'Jeez', I hear you sigh. 'Not another one; spare us...' (There'll be plenty of you saying this..!!) lol

    The thing about Pup is that every included app (and in the average 200 MB .iso image, there's somewhere around 150+ of these) has been carefully picked to be as lightweight as possible. Consequently, I can be multi-tasking with at least half-a-dozen apps open (including a 'heavy' one, like a browser), and the X2 takes it in its stride, barely breaking a sweat in the process.....

    They might not be especially 'pretty' to look at, most of 'em.....but they all,without fail, get the job done, as quickly and efficiently as possible. And I'd put functionality over eye-candy ANY day of the week.

    For Puppy, even an elderly 'duallie' is still a powerhouse..!

    Can different programs use different cores, or are multiple cores only useful within individual programs? My PC has like 50 processes running as soon as a turn in on before I can even start to use it for my work - everything from Dropbox and anti-virus to Windows Search and Windows Update (not to mention Google Update, Corel Update, and Adobe Update). Can these processes use different cores, so they aren't competing with what I'm trying to work on?

    • Doc

      Any task can spawn a single thread or several. For example, Adobe Photoshop might spawn several threads in order to process a filter. Each thread can only run on one core; it's not possible for two cores to safely change memory that the other core *might* be using. Processes with threads that are user-intensive (such as moving the mouse pointer or processing what you're typing) are assigned to less-used cores by default, so you'd have to really bog down the computer to affect them.
      In another case, remember when computers only had 1 core? Each process (and each process's threads) run on "timeslices," usually 1/1000th of a second or so, before stopping and being assigned to another thread that may require CPU time (and any thread can go "idle," telling the process manager "My work is done; wake me up when it's time to do something again.") This is how dozens (or hundreds!) of processes and their threads "multitask"; having multiple cores simply means there two or more threads that can run at the same time as long as they don't mess with each other's memory. Intel CPUs with Hyper-Threading can switch between two threads while waiting for main memory to catch up with idle threads; AMD's new Ryzen CPU architecture is said to have something similar. Hope this isn't too confusing...

    So, if I understand this correctly, as most consumer level, non-media programs are only capable of utilizing a single core, dollar-for dollar, my grandmother would be better off with a higher clock speed CPU with fewer cores and my gamer nephew would be better off with a lower clock speed with more cores.

    I appreciate that a higher clock speed PLUS more cores is optimal, but I am talking trade-offs within products of the same price range.

    Do I have that right? Or is there something that I am missing?

      Almost every CPU now made (except for the really low-end stuff, like Intel Atom) is at least dual-core. The best thing to do is look at a few different computers, whether laptop or desktop, preferably with the option to play with it for awhile. Once you have a good idea of the different performance levels, buy the best computer you can afford - you're going to be using it for awhile. Don't skimp on CPU speed, RAM, or storage (hard disk or SSD) space. Pick a decent-looking screen, too. Nothing will hit you in the wallet harder than buying a PC to find it's too slow (opening your web browser takes forever; Word or OpenOffice Writer takes forever to reformat a page; your printer takes 2-3 minutes between pages because your PC can't handle printing).
      The amount and speed of the RAM in the computer will also affect the speed, whether it's office tasks or 3D gaming. An SSD (at least big enough to store Windows, if nothing else; you can add a spinning hard drive for large files) is also a good upgrade.

    Multiple cores are for performing multiple tasks simultaneously whereas more GHZ will help you to achieve better/faster performance for specific tasks, more core does not merge within for a single operation. Hence HTC will be better at multitasking whereas blackberry will perform better at demanding tasks such as high tech gaming.

    Pardon my ignorance here, I've jsut bought a second hand desktop PC dual core HP short form.
    I recently found a 2nd hard drive for it - a thrown out Western digital 250 GB.
    When I installed this hard drive I notice it splits into 2 drives (as well as the original C Drive) showing 164 GB and 87-odd GB each. (the 87 GB seems to hold the programs and the 164 GB is all freed up). What is this split up, is it because the PC is 'dual' core. ? I'd rather have all my files in just the one 250GB drive.

    I dont know whether Chris Hoffman used a bad example or whether he really does not understand multi-threading, multitasking and pipelining. Both the examples he chose above are not the best cases of non linear mixes. Unzipping an archive is a compute bound function and will have few or no I/O interrupts. Browsing on the other hand is subject to very slow I/O and many interrupts where such interrupts permit the Interrupt Service Routine to context switch to the next or highest non suspended task.
    Furthermore traditional linear processes can never be multi-tasked and can only be optimised if the data is subject to random arrival rates and hence continuously varying queue lengths usually following a Poisson distribution- what this means is that during intervals in the distribution the ISR can context switch to other tasks. Users of Laptops ipads and the like do not run nuclear reaction or world economy models nor do they do major movie post production involving high rates of rendering (compute bound) jobs so the pseudo antics of sizing a baby system wrt to 3GHz QC or DC is a pretentious nonsense.

    They say that processors are for smooth working for any application to run then why is there a RAM there? What's the difference between a RAM and Processor?

    The technology which we are using today is good but the budget of some peoples are not enough to analized this latest technology so my request is the this technology should be made little cheaper inorder to make kind achievement search for some talent in this world...

    Is there a link/site anywhere which lists the main applications such as microsoft office, adobe creative etc and shows if they support multi-threading or not?

    Would be useful to know.

    There was 2 good points in this post

    1)Set Affinity.-- This was a good trick. Never knew I could do this
    2) "It’s becoming a more crucial problem, as the future looks to be computers with more and more cores instead of fewer cores at faster and faster speeds."

    Fewer cores at faster speeds that should be the way to go.

    So, I guess the conclusion is, if you multitask a lot, go for more cores.

    BTW, I heard Intel Core i3 has 2 cores, but can do 4 threads, does that mean one core can multithread?

      I'm pretty sure all i3's are dual core with four threads with Hyper-threading. Each core can do two threads

    Any way to find no. of cores in my computer ? As much as I know its i3 and 3.1 GHz.

      Hi Bro,
      You can check that out using Device Manager-->(open sub) Processor
      and you will see how many processors are available for your system.
      (example: I have a i7 so i can see 8 processors on the list)

      • Md Mukhtar Mohsin
        May 8, 2013 at 10:18 am

        Thanks , but bad luck to me ,it shows only 2 cores.

    • Colper
      May 7, 2013 at 2:55 pm

      What I would do:

      1. Start button or C: drive
      2. click on "System Properties" on the top ribbon.
      3. Copy and Paste the line on "Processor". i.e. Intel Pentium 2400 @ 2.4 GHz
      4. Google the line you just copied. Intel's results should be one of the top choices. Scroll down to find all of your specs.

      • Md Mukhtar Mohsin
        May 8, 2013 at 10:21 am

        Thanks bro but no need to google as Tim Vels told above you can see it in device manager .

        • Colper
          May 8, 2013 at 2:37 pm

          No prob. Glad you found what you were looking for. I like to google to see all the other specs and capabilities that come with the processor. Intel lays it out nicely. Cheers!

      May 7, 2013 at 2:58 pm

      Sorry, Forgot to mention in Step 1. Click on start Button then and/or "Computer or My Computer" depends on your OS. Then follow to "System Properties" on the top ribbon.

      By the name of the CPU either it's Dual Core (two cores) or Quad Core (4 cores) and so on.

      • null
        May 8, 2013 at 1:52 am

        the i7 is decribed as Intel Core i7 which is not descriptive of its quad core
        8 thread capability.

    hyper threading used to be on older Pentium 4 CPUs as well, does that mean they were 'dual core' as well?

    • null
      May 7, 2013 at 2:41 pm

      no, hyper threading is NOT dual core. basically it can do two separate tasks at once by using different instructions but on a single core.

    I have a dual core processor running at 2.3Ghz which is average for causal uses but the upper number of core is good for gaming or high demanding tasks.

      May 7, 2013 at 2:44 pm

      very few games right now take advantage of multiple cores. I'm pretty sure Battlefield 3 is one of them. In the future this will be true, but right now more cores is not much of a bonus unless your streaming or multitasking.

    Just wondering, why don't they have a tri-core or a pent-core?

    • Jumbybird
      May 7, 2013 at 2:34 pm

      Even numbers fit better on a piece of silicon. Otherwise you have wasted space. If you have 3 cores a quarter of the chip will be empty

    • null
      May 7, 2013 at 2:35 pm

      Yes, Tri-cores are often (if not always) quad-core with one of the cores disabled.
