What Makes a Computer Fast? (Explained)

There are a lot of factors that contribute to how fast a computer is.

What Makes a Computer Fast

It could be the processor, the amount of RAM, the hard drive, or even the software that’s installed.

But at the end of the day, it all comes down to how fast electrons can move. That’s right – speed is nothing more than an electrical current.

So if you want a fast computer, you need to find a way to get those electrons moving quickly. One way to do that is to use a solid-state drive instead of a traditional hard drive.

SSDs don’t have any moving parts, so they can access data much faster than a traditional hard drive. And since there are no moving parts, there’s less chance of something going wrong and causing a slowdown.

So if you’re looking for a speed boost, switching to an SSD is a good place to start.

So let’s get into what makes computers faster.

What makes a computer faster RAM or processor?

When it comes to making a computer faster, there are two schools of thought: those who believe that RAM is the key to speed, and those who think that the processor is more important.

The truth is, both components play a role in determining a computer’s speed. RAM provides the temporary storage space that enables a computer to quickly access the information it needs.

However, if the processor is slow, then the computer will still be sluggish. Likewise, a fast processor won’t be able to do much if there isn’t enough RAM to store all the information it needs to access.

In short, you need both a fast processor and enough RAM to get the most out of your computer.

What makes a computer faster RAM or SSD?

If you’re looking to speed up your computer, you might be wondering whether you should invest in more RAM or a solid-state drive.

Both options can give your machine a boost, but which one is best for your needs? More RAM will help your computer to run more programs at the same time without slowing down.

However, if your programs are constantly swapping out memory for disk storage, you’ll see little benefit from extra RAM.

A solid-state drive, on the other hand, can make a big difference in boot time and how quickly programs load. If you’re looking for the biggest speed boost possible, adding an SSD should be your first priority.

Of course, there’s no need to limit yourself to just one upgrade – adding both more RAM and an SSD will give you the best of both worlds.

Does more RAM make a computer faster?

Like many people, you may be wondering if upgrading your computer’s RAM will make it faster. After all, more is almost always better, right?

Well, not necessarily. More RAM can help your computer to run more programs at once without slowing down, but it won’t make individual programs load any faster. So if you’re looking for a way to speed up your computer, adding more RAM is unlikely to help.

But if you often find yourself running multiple programs at once or working with large files, then upgrading your RAM could be a worthwhile investment. Just don’t expect it to work miracles.

How do I choose a fast computer?

When it comes to choosing a fast computer, there are a few things to keep in mind. First, consider what you’ll be using the computer for.

If you’re a graphic designer or video editor, you’ll need a machine with a powerful processor and plenty of RAM. For general office use or web browsing, however, you can get by with something a bit less powerful.

Second, take a look at the hard drive. A solid-state drive will be much faster than a traditional hard drive, so it’s worth paying extra for one if speed is a priority.

Finally, make sure the computer has good cooling – a fast machine will generate a lot of heat, so it’s important to choose one that won’t overheat.

With these factors in mind, you should be able to find a fast computer that’s just right for your needs.

Is 16GB RAM enough?

I’m often asked if 16GB of RAM is enough for gaming. The simple answer is: it depends. For most PC games, the answer is yes – 16GB will be plenty.

Even the most demanding AAA games tend to max out at around 8-10GB of RAM usage, leaving plenty of headroom for other applications.

However, there are a few exceptions. Games that make extensive use of modding or high-resolution textures can benefit from more RAM, and those who stream their gameplay or run multiple applications in the background may also find themselves needing more than 16GB.

Ultimately, it comes down to how you use your PC and what your specific needs are. If you’re not sure whether you need more than 16GB, my advice is to start with that amount and upgrade only if you find yourself running into performance issues.

What is more important cores or RAM?

Anyone who has ever shopped for a computer knows that there are a lot of technical terms to keep track of. Two of the most important aspects of any computer are its processor and memory.

The processor, or CPU, is responsible for carrying out instructions, while the memory, or RAM, stores data that can be accessed quickly by the CPU. So which is more important: cores or RAM?

The short answer is that it depends on what you want to use your computer for. If you are doing simple tasks like browsing the web or checking email, then a dual-core processor with 4GB of RAM should be plenty.

However, if you are doing more demanding tasks like video editing or gaming, then you will need a quad-core processor with 8GB or more RAM.

In general, cores are more important for performance while RAM is more important for memory-intensive tasks.

So if you need a fast computer, look for one with a high number of cores; if you need a computer that can handle a lot of data, look for one with a high amount of RAM.

What is the difference between RAM and processor speed?

There’s a lot of confusion out there about the difference between RAM and processor speed. So let’s clear things up once and for all. RAM, or random access memory, is the temporary storage area for data that your computer is currently working with.

The processor, on the other hand, is the part of the computer that actually processes that data. So think of it this way: The processor is the brain and the RAM is the short-term memory.

Just like you can’t think very clearly when your head is full of jumbled thoughts, your computer can’t work very efficiently when its RAM is full. That’s why it’s important to have enough RAM to hold all the data your processor needs to work with at any given moment.

As for processor speed, that refers to how fast the processor can carry out its instructions. A faster processor can obviously handle more instructions in a given amount of time, which means it can get through its work more quickly.

So if you’re looking to speed up your computer, you need to focus on both the amount of RAM and the processor speed. Adding more RAM will help your computer hold more data so that its processor can work more efficiently.

And upgrading to a faster processor will help your computer carry out its instructions more quickly. But ultimately, you need a balance of both to get the best performance from your machine.


CPUs are complex pieces of hardware, but by understanding a bit more about how they work and what makes them fast, you can make better decisions when buying or building your next computer.

We hope this article has helped demystify some of the concepts behind CPU speed and given you a better idea of what to look for when shopping for a new machine.
