Guide: Is Laptop RAM Different VS. Desktop RAM

Did you know that RAM is one of the most important parts of a computer system? It can be the difference between a slow, frustrating experience and lightning-fast performance. In fact, as with any other component in your system, selecting the right RAM for your laptop can make all the difference. The good news is that you don’t have to be an expert to figure out what kind of RAM you need.

But there are some disparities between desktop and laptop RAM technologies that might not be immediately obvious. In this guide, we’ll get into those details so that by the end you’ll know is laptop ram different from desktop ram, and how much RAM your laptop should have (and what type).


When choosing a device (laptop or desktop), we tend to check its specifications. But one of the checklists we ALWAYS neglect is to check the RAM. In this section, we will reveal which device has the best RAM and how this specification affects laptop and desktop performances.


The first difference between laptop and desktop RAM is capacity. A laptop’s RAM capacity can vary depending on how much storage space you’re willing to sacrifice, but even the highest-end laptops have far less RAM than desktops. Laptop memory capacity ranges from 4GB up to 32GB, with most models falling somewhere in between. Desktop computers’ RAM typically has 8GB or more installed by default, and some can be upgraded to 64GB or even 128GB (though I’d caution against anything over 16GB).


The second difference between laptop and desktop RAM is speed, and it’s not all good news for laptops here either! The reason laptops tend to have slower RAM than desktops has to do with their power consumption requirements. This is because they’re designed for mobile use, they have lower power requirements than desktops. This means that manufacturers often use slower DDR2 chips rather than faster DDR3 or DDR4 chips in order to save energy while running at full speed


The second major difference between laptop and desktop RAM is the type of memory used in each. While both use dynamic RAM (DRAM), there are several different types of DRAM that are optimized for different uses.


The Dynamic Random-access Memory is the most prominent variety of RAM installed in computers today. It’s inexpensive and can be found on many laptops and desktops alike. The only downside to this type of RAM is its tendency to lose stored data when power is disconnected. This means if you turn off your laptop without shutting down (or close it while running an app), any data still being processed will be lost once you reopen it again!

And this can be problematic when working with large files or applications where data transfer takes a long time! However, this isn’t too common with laptops because most people close their machines as soon as they’re done using them anyway.


Double Data Rate refers specifically to DDR4. This type works with higher clock speeds than traditional DDR3 modules. In fact, some have been tested at up to 4000MHz. As such, these modules offer better performance for those who need heavy graphics processing capabilities like video editing or gaming. However, they’re also much more expensive than other kinds of memory because they require special hardware support inside your computer’s motherboard/CPU chipset combo system architecture design.


RAM frequency is the speed at which it can access data, while CAS latency is how fast it can access specific memory locations. The lower the computer’s CAS latency means there will be fast access to data, and therefore precise execution of instructions.

In general, desktop memory has a higher CAS latency than laptop memory. This means that when choosing between laptop and desktop RAM for your computer or laptop, you should choose a lower CAS rating over a higher one if possible.

Ram frequency

Frequency is widely measured using megahertz (MHz), which means how many cycles per second are there. It’s the number of times a processor can execute instructions in a second, which usually increases as new processors are released. You can imagine frequency as being like a car engine. It’s not as important as other specifications like latency and bandwidth. But it still makes a difference because the faster your processor runs, the better its performance will be at completing tasks quickly.

However, increasing your computer’s frequency won’t improve performance if you have higher-end components than what’s required for your workload (for example, if you’re running an older desktop PC with modern laptop components).

CAS latency

The CAS latency of RAM is the time it takes for the CPU to access data from RAM. The CAS latency is measured in nanoseconds (ns). This is a function of the memory type and the clock speed of the RAM. For example, an 1866 MHz DDR4 SDRAM has a CAS latency of 17 at JEDEC standard and 16 at Intel standard.


Q: Why does my computer have to have RAM?

A: RAM is a type of memory (storage) that stocks information while your computer is running. When you turn off your computer, all data kept in RAM is gone. In addition to storing programs and files temporarily, RAM also keeps track of what’s going on inside the computer at any given moment. For example, where information is being read from or written to and how quickly it’s moving between internal storage devices like hard drives and optical discs.

RAM also helps load programs into memory so they can run quickly when you turn on your machine. It’s usually referred to as “random access memory” because its contents can be accessed randomly (in any order).

Q: What makes RAM so special?

A: As mentioned, RAM is the busiest specification of a computer. It’s a combination of high-speed semiconductors, capacitors, and other components that store information as electrical charges. Unlike most other forms of memory, RAM operates at extremely high speeds to enable it to read and write data quickly. This makes RAM ideal for storing instructions for the CPU and short-term storage (recall) when executing those instructions.

Q: What is the variance between RAM and hard drives?

A: RAM is the primary storage area for your computer. On a Mac, it’s located on the motherboard and is used to store data while it’s being processed by the CPU. Data stored in RAM has the shortest access time, which means that things like changing applications and opening files happen very quickly when you’re using RAM.

As opposed to hard drives, which are non-volatile (store data even when turned off), RAM is volatile (lose its contents when turned off).

Q: Will adding additional RAM induce the speed of my computer more?

A: Increasing the RAM to your laptop or desktop can make it faster, but only if you’re running out of memory. If your computer has enough RAM for all the programs and files you’re using at the moment, adding more will not speed up your computer.

RAM is a temporary storage space for your computer. It rations data that your computer demands to get access swiftly, such as while it’s running an application or playing a game. When you close an application or game, this information goes back into long-term storage (your hard disk).

It’s not possible to add more RAM to a computer because it doesn’t have any permanent storage spaces. The only way to increase its memory is by buying additional modules of DRAM (dynamic random access memory) chips that connect directly into the motherboard by plugging in place of existing ones (or there may be an empty slot where one could go).

Q: How does RAM work with the rest of the system?

A: RAM is used to store data temporarily. It’s a form of memory that stores detail your computer inevitably requests for access promptly. This includes the files you are currently working on, the web pages you have open in your web browser, and temporary files created by programs running on your PC.

For example, when you’re editing photos in Adobe Photoshop, RAM allows you to work with large image files without having them load from storage all at once. This way, if something goes wrong during the process (like accidentally deleting some pixels), it’s easier for you to recover than if it had happened while trying to load an entirely new file instead!


RAM, or memory as it is more frequently called, is one of the most commonly misunderstood computer parts. As a result, many people end up making purchasing decisions based on marketing gimmicks and not actual needs. Hopefully, this guide on is laptop ram different from desktop ram has helped you clear this confusion, and finally walked you through the best device suitable for your needs.
