These days, it’s not unusual for individuals or families to have more than one type of computer. If you’re looking to carry your computer to work or on vacation, you obviously need a laptop. And some have slimmed down to weigh as little as a couple of pounds.
If mobility isn’t a concern, get a desktop, because it’s very likely that you’ll get more performance for the same money—plus more flexibility in customizing the machine once you buy it. (That’s one reason lots of serious gamers have desktops.)
Those are two major categories of computer, but there are several variations to consider—and we haven’t even mentioned the choice of operating system yet.
Choices among computers are becoming more confusing as the boundaries between categories blur. For instance, some new desktops are almost as small and inconspicuous as a laptop. Conversely, you can easily find a laptop that’s just as powerful as a typical desktop. And then there are some slightly unconventional categories, such as laptops that can be used liked tablets and all-in-one desktops that don't need a separate monitor. For more, check our full computer ratings (available to Consumer Reports members).
Many people have moved away from desktops in the past decade. However, they still may be useful for many consumers.
Desktops typically offer more performance for the money than laptops and are less expensive to repair. They may allow for a more ergonomically correct work environment, generally come with better speakers, and allow you to view your work on a larger screen. Click here for our computer ratings.
Though they require a lot of room under or on top of your desk, full-sized desktops are the least expensive and the easiest to upgrade and repair.
At less than half the size of full-sized desktops, compact or slim desktops are ideal if you lack space under your desk or if you plan to put the computer on your desk.
All-in-one desktop computers, also known as "all-in-ones," incorporate the computer and monitor in one case. The components are tightly packed behind and underneath the display, making them difficult to upgrade or repair. Meant to be space-savers, they're also designed to look less stodgy than traditional computers. You'll pay a premium for these models.
The sky's the limit for gaming systems. You get the fastest processors, the most sophisticated graphics cards, multiple large hard drives, and lots of RAM. Cases are usually large and offer room for additional components like extra memory or dedicated sound cards. These tend to be quite expensive.
Laptops let you use your computer away from your desk, but you pay for that mobility with a keyboard that's a little more cramped, a higher price, and (sometimes) reduced performance. A laptop can also be more difficult and expensive to repair than a desktop.
Whether your main consideration is portability or power, screen size will be an essential factor in deciding which type of laptop is right for you. See our computer ratings (available to CR members) for more.
A 10- to 13-inch laptop is best for people frequently on the move.
Why? For one, these laptops are typically light enough to be brought, say, to and from your office without needing the strength of a powerlifter. They may not have the fastest processors around, but laptops in this size range are nowadays more than capable of handling everyday productivity tasks with ease. Battery life varies but you should be able to get through at least a full workday nowadays.
This size range offers the ideal balance of performance, portability, and price for many users. Midsized models are a good choice if you take your machine along less frequently or if you need to use it extensively for work or school. Such a laptop can easily be configured as a desktop replacement.
Until a few years ago, only 17-inch and larger models had graphics processors with dedicated video memory, but now some 14- to 16-inch models have them, making them suitable for gaming.
For photo editing, our tests of the 15-inch MacBook Pro reveal its screen to be among the best we’ve seen for color accuracy and crispness.
For folks wanting a desktop replacement, big enough to sit semipermanently in one place but portable enough to take from room to room, these laptops will deliver. They tend to use top-performing processors with standard hard drives that give you tons of storage, though not top performance.
You might find some with better speakers than smaller laptops can offer. However, they still won't sound as good as external speakers. And, of course, the larger screen can make it more comfortable to work on multiple windows or large spreadsheets.
Lighter and less expensive than most laptops, these highly mobile devices offer an extra dose of portability and many—but certainly not all—of the features. Click here to check our computer ratings.
Chromebooks use Chrome OS, an operating system developed by Google. They're generally inexpensive, with some starting at just under $200, and are designed for users willing to work on and store most of their files online. Since Chrome OS is very similar to the popular Chrome web browser some users may have an easier time using a Chromebook than other computers.
On the downside, there’s not a lot of storage space on a Chromebook, so consumers should be prepared to stream, instead of download, content like music and movies. You need access to the internet to get the best work out of one of these machines. And these aren't workhorse computers, though they are fine for office productivity work like email and spreadsheets, and browsing the web.
Some laptops are known as two-in-ones and either have a keyboard that can be bent around the back of the display or whose keyboard can be detached entirely. These are called convertibles and detachables, respectively. They may be useful if you want to be able to use your laptop in bed while holding it like a tablet (to stream video, say) or if you want to prop up the laptop like a "tent" to more easily show off the display to other people nearby.
Apple does not make a two-in-one laptop but you could pair an iPad with a keyboard to have a similar experience.
See our tablet buying guide for detailed information about shopping for a tablet. But in brief, for some users a tablet can take the place of a laptop. These machines are lightweight and highly portable. They’re multifunctional, serving as web browser, e-book reader, movie viewer, and music player.
They weigh from just less than a pound to about 1.5 pounds and have 7- to 10-inch touch screens. And in our tests, battery life ranged from 4 hours to nearly 13 hours. Tablets are not ideal for office productivity tasks, but you can add a keyboard to many of them.
Speed matters. Processors with multiple cores can process more data simultaneously, with four cores now increasingly common on laptops. Our ratings say how many cores a laptop's processor has.
Clock speed, measured in gigahertz (GHz), along with the number of cores and other factors, determines how quickly a processor can process information. Many processors can up the speed a bit for a brief time to yield maximum performance. Generally, within a processor family, the higher the clock speed, the faster the processor. Clock speeds typically start at around 1 GHz for a mobile processor. Speeds can exceed 5 GHz for a desktop processor.
Power Consumption
Another important factor when choosing a processor, especially for laptops: Lower power consumption equals longer battery life.
If you're looking for a very basic or budget computer to browse the web, email, and work on Office documents, basically every processor on the market should be sufficient.
If you plan to watch high-resolution videos or play mainstream games, you should consider the Intel Core i5 and AMD's Ryzen line of processors.
How Much Memory?
The more memory a computer has, the faster it is, up to a point. Memory is measured in gigabytes (GB). On both desktops and laptops 8GB has become common, with 16GB found on higher-end devices. Unless you regularly have multiple large apps open at the same time, 8GB should be your target.
Operating System
Windows 10 brings a more uniform interface across a variety of devices: computers, tablets, Xbox consoles, and smartphones. In addition, "universal apps" developed for Windows 10 will look and work the same on a variety of devices. And far more games are available for Windows computers than for Macs.
Macs can be more expensive, but they're less prone to most viruses and spyware (in part because there's more Windows PCs out there than Macs, making them a bigger target for hackers), and Apple's support has been tops in our surveys. The company's phone support is free for only 90 days, but you can get unlimited technical support through the Genius Bar at any Apple Store. The latest version of macOS (previously known as OS X) is called Catalina and was released in the fall of 2019.
Graphics Adapter and Graphics Memory
Also known as the video card, graphics processing unit (GPU), or graphics card, this hardware is responsible for drawing what you see on your screen. Graphics processing comes in two basic flavors: It can either be integrated into the same chip that's running the rest of the computer or it can run on a discrete piece of equipment.
Most computers have integrated graphics. This has usually been the less expensive and lower-performing option—fine for most tasks but not for serious gaming. If you play mainstream and extreme games with all the visual effects turned on or if you edit video, especially HD and Ultra High Definition (4K), you need discrete graphics. Light video editing and gaming and all other typical computer tasks will do fine with integrated graphics.
Some new CPUs integrate discrete-class graphics, offering excellent graphics abilities without adding a separate chip.
Solid-State Drives: SSDs are a different type of storage technology, letting your computer access data without the moving parts required by a traditional hard drive. They are also the single largest performance boost you can give a computer over an identical computer with a hard drive.
SSDs don't have the spinning disk of a conventional hard drive, so they use less power, work more quietly, and should be more resistant to damage—and less likely to fail mechanically. And because there are no moving parts, access to data should be quicker.
Although they once cost several times as much as traditional hard drives and had smaller capacities, prices are coming down and capacities are inching upward. In general, Consumer Reports recommends solid-state drives over hard drives.
Hard Drives
Also known as a hard disk, this type of drive uses a spinning hard disk and uses more power than a solid-state drive. It is also slower overall.
Bigger is better. Hard-drive sizes are measured in gigabytes and terabytes, and commonly range from 250GB to more than 1TB.
Speed is equally important and is measured in rpm (revolutions per minute). A slow hard drive will take longer to start up the OS and programs, and complete tasks (such as installing programs or scanning your hard drive for viruses).
For best performance, get a desktop with at least a 7,200-rpm hard drive or a laptop with a 5,400-rpm hard drive.
Hybrid Drives
Lower-priced hybrid drives, which combine a hard drive with solid-state memory, represent a good compromise.
Optical Drives
Blu-ray Disc (BD) drives are the newest standard. They're capable of playing Blu-ray movies and can store 25GB (single layer) or 50GB (dual layer) of data.
Many of today's laptops come without an optical drive, saving weight and cost. With high-capacity flash drives available, extra storage isn't a problem on these models. But installing older software—usually distributed on a CD or DVD—could be a problem. Most of today’s software is distributed via download, so there’s little need for an optical drive.
The Battery
When not plugged into a wall outlet, laptops use a rechargeable lithium-ion battery for power. Laptops go into sleep mode when used intermittently, extending the time between charges.
You can lengthen battery life if you dim the display, turn off WiFi connectivity when it's not needed, and use only basic applications.
An increasing number of laptops have batteries that cannot easily be removed by users, which means they'll need to be taken to service centers when they die.
Although most computers come with a basic, predefined set of features, that doesn't mean you don't have choices. Use this guide to help wade through your options. For more, check our computer ratings (available to CR members).
Screen sizes (measured diagonally) generally range from 15 to 24 inches, but you can find larger ones. The most common sizes are 19 and 20 inches.
Most are wide-screen, which fit wide-screen movies better but give you less screen area per inch. Those who plan to edit photos or videos should note differences in color, viewing angle, contrast, and brightness. Monitors are often less expensive when bundled with a new computer.
A 15- to 16-inch display should suit most people. Displays that are 13, 14, and 17 inches are also common, and some manufacturers are also offering 11-inch laptops.
The screens on most laptops are glossy instead of matte. Glossy screens have more saturated colors and deeper blacks but are also more prone to glare. Like desktop monitors, most laptop displays are wide-screen to show wide-screen movies at their best.
Borrowing from tablets, companies have begun including touch screens on many laptops. The notable exception is Apple. These have custom, touch-enabled multimedia apps and include multitouch capability, which lets you use your fingers to zoom, turn, and scroll.
Windows 10, which is engineered to work on mobile devices as well as conventional computers, appears to be accelerating the trend. Computers with touch screens tend to cost more.
For connecting to the internet, all desktops come with an Ethernet port that lets you run a cable between your desktop and your router. If it’s not possible to run such a cable through your home, consider using a WiFi adapter. Many desktops have this built in. If not, you can buy one for about $40 and plug it into a USB port. You’ll also need a wireless router.
Laptops come with wireless built in, and some have a port for connecting an Ethernet cable, although many are ditching it to save space.
Most of those that come bundled with desktops are optical, meaning light sensors on their undersides track movement. If you have a wireless mouse, you won’t have to deal with a cord, but you will have to recharge or replace the batteries every few months.
The latest port to arrive on computers is USB-C. It’s reversible, so you’ll never insert a USB-C plug in the wrong way. It can also be used to supply power to your laptop. With an adapter, it’s compatible with earlier versions of USB.
USB ports let you connect a variety of add-on devices, such as digital cameras or external hard drives, as well as flash drives for copying files to and from the hard drive. Having these ports at the front of the desktop case makes connecting devices more convenient.
An Ethernet port or wireless network card lets you link several computers in the household to share files, a printer, or a broadband internet connection.
Thunderbolt, a very fast data-transfer port, is also used for connecting external devices. The latest version, Thunderbolt 3, uses a USB-C connector. However, there are fewer compatible devices available for it than there are for USB.
An HDMI output jack lets you run a video cable from the computer to a TV, so you can use the computer’s DVD drive to view a movie or stream from an online service such as Netflix to a TV instead of watching on a computer monitor.
This list comprises the major computer brands. In choosing a brand, consider the manufacturer's technical support and reliability as shown in our surveys.
