Why processors in laptop and desktop are differently specs?

I won't give up my desktop computer anytime soon.Antonio Villas-Boas/Business Insider
  • I have a big towering desktop that I can't carry anywhere and stays in a single room at my home, but I still prefer using it for work and play over a laptop.
  • The right desktop can cost less than a laptop, and I can get my work done more quickly and more smoothly than I can with a laptop.
  • I still have a laptop just in case I need to go mobile, but for anyone who's finicky about their computer's performance, there's nothing better than a big, heavy desktop.

It's 2019, and I still use a desktop.

In fact, I actively prefer using a desktop over a laptop.

It sounds ridiculous, but desktops make more sense than a laptop for a lot of people. Usually, those people value performance over portability, or they'd rather not pay for a laptop's comparatively high price tag.

Sure, powerful laptops out there offer the best of both worlds for those who need power and portability just hook up a laptop to a monitor if you need a bigger screen and you're set. Thing is, though, powerful laptops don'treally offer the best of both worlds. They're often relatively heavy and large, and while they may be powerful, they're not always as powerful as a desktop with the "same" specs.

Check out why I use a desktop in this day and age:

You get better performance, even if they have the "same" parts.

Lenovo/BestBuy

There's no two ways about it. A desktop with similar parts as a laptop works faster and smoother.

That's because desktops usually come with full-size parts that are often more powerful than the similar counterparts designed for laptops. It's especially noticeable with processors and a computer's overall speed.

Laptops may come with processors that have similar model numbers, but they're rarely as powerful as the desktop counterparts.

For example, my 2016 15-inch MacBook Pro has an Intel Core i7 6700HQ with four cores. The "HQ" is Intel's line of high-performance mobile processors, so it's the top of the line model for laptops. Meanwhile, my desktop has an Intel Core i7 6700K, also with four cores. You'd think both computers would have similar performance because they have the same model number, but they don't. My desktop is noticeably smoother and faster because its full-size desktop processor is more powerful, despite having the same model number as the processor inside my MacBook Pro. In fact, my desktop's processor is up to 28% more powerful than my laptop's, according to benchmarks, which is a pretty significant difference.

Even when laptops and desktops are evenly matched in performance, desktops tend to be significantly less expensive.

Dell/BestBuy

Let's compare a desktop and a laptop from Dell, both with Core i5 8400 processors that perform pretty similarly, according to benchmarks.

The Dell laptop costs $1,200. The Dell desktop with similar specs costs $440. You would need to factor the cost of a monitor for the desktop if you don't already have one. Inexpensive 24-inch monitors that get the job done can be as cheap as $150.

For reference, here are the specs for both computers:

Laptop:

  • Intel Core i5 8400H [high-performance series]
  • 8GB RAM
  • 500GB hard drive

Desktop:

  • Intel Core i5 8400
  • 8GB Ram
  • 1 terabyte hard drive

Desktops are usually associated with being big, bulky, and heavy, but some desktops aren't big at all, or they come with built-in screens.

Lenovo

There are some pretty slim and small desktops you buy or build yourself that can fit around your work area without taking up too much space.

Most computer companies, including Apple, sell all-in-one desktops where the entire computer is built into the screen enclosure. These are great if you want to avoid messy wires everywhere and want a neat package.
