Best all-in-one computers in 2024: our top picks tested and ...

PCs that squeeze all the key components into the display are known as all-in-ones, and the best all-in-one computers give you all the capabilities of a desktop PC in an elegant display that's easy to fit on your desk.

ZHONGKANG supply professional and honest service.

I know because my team and I regularly test and review the best all-in-one PCs from the major manufacturers. While few are powerful enough for real gaming or other demanding work, the modern 24-inch Apple iMac we regularly recommend is surprisingly capable thanks the speedy M3 chip which drives it.

If you're on a budget, something more affordable like the MSI Modern AM271P won't make you feel like it. But if you can afford to splurge and would like an alternative to an iMac, the HP Envy 34 is a luxurious all-in-one computer with a lovely 34-inch display and a built-in wireless charger.

Read on for detailed comparisons, full reviews and a suite of test scores which back up our claims that these are the best all-in-one computers you can buy.

The best overall

The Apple iMac M3 looks an awful lot like its predecessor, but under the hood this all-in-one is powered by the all-new Apple M3 chip that helps propel it to our top spot on this list.

That cutting-edge slice of Apple silicon gives the 24-inch iMac a much-needed shot in the arm, since the previous model was powered by 's Apple M1 chip. That model's still fine for basic work, but the M3 upgrade gives the iMac more power and more features than before, including upgraded wireless connectivity, better image processing and support for modern graphics tech like hardware-accelerated ray tracing. 

Factor in the iMac's great speakers and beautiful 4.5K display and you start to see why it's so easy to recommend to families, students and teachers.

Reasons to buy

Reasons to avoid

The MSI Modern AM271P 11M is an awkwardly-named all-in-one that's quite good if you need something relatively affordable that's capable of tackling the day-to-day tasks of handling business and getting things done.

That's because this PC packs a speedy 11th Gen Intel Core i7 laptop CPU into its display along with 16GB of RAM and a 512GB SSD. The fact that it's powered by a top-of-the-line laptop CPU means this MSI can deliver a lot of speed and functionality even though the entire PC is housed inside the display itself. And with its built-in VESA mount, you can set it up on the included stand or mount it on a wall or monitor arm for more convenient workplace setups. Plus, you get a p webcam, keyboard and mouse packed in with every unit -- though all three leave a little something to be desired, so you may want to replace them with your own favorites down the road.

The HP Envy 34 is an elegant Windows 11 all-in-one that impresses thanks to its vibrant 34-inch 5K screen and powerful performance. 

It's a legit rival to the Apple iMac thanks to that lovely 

The updated Surface Studio 2 gets beefier processing and graphics hardware, switches to all-solid-state drives for storage, and gets an even better version of the PixelSense display that offers enhanced brightness and contrast. It's one of the best all-in-one computers we've seen, and our top pick for media creators and artists.

How to choose

How to choose the best all-in-one computer for you

Even the best all-in-one computers generally don't deliver a ton of power, so if you need a PC for serious photo/video editing, coding or playing games you should probably look elsewhere--like our regularly-updated list of the best gaming PCs.

But if you need an all-in-one for general computing, you have a lot of great choices. The first thing to decide when shopping for the best all-in-one computer for your needs is what operating system do you want: macOS or Windows?

While there are a few all-in-one Chrome PCs, the vast majority run on either Apple or Microsoft's operating system. And while Windows AIO PCs like the HP Envy support a wide variety of software and are compatible with any game you care to run, those strengths of Windows matter less when it comes to all-in-ones because these PCs generally don't have the power or cooling to run the most demanding apps and games anyhow.

So if you prefer macOS, you should definitely feel good about choosing an all-in-one like the 24-inch iMac. Macs are just as capable as Windows PCs these days, and the webcams built into Apple's PCs are excellent. Plus, the modern iMacs can also run apps from Apple's App Store and support modern features like iPhone Mirroring, so you can easily access iOS apps or even your 's home screen right on your desktop PC.

How we test the best all-in-one PCs

How we test to find the best all-in-one PCs

Every all-in-one we review goes through a variety of benchmark tests in our lab as well as long hours of real-world use. As with our laptop reviews, we use a colorimeter to measure the brightness, color accuracy and color gamut of each all-in-one's display.

For performance, we use the Geekbench 4 test to measure a system's overall processing abilities. We also run a custom spreadsheet test to see how long a PC takes to match thousands of names to addresses. To evaluate each system's hard drive speed, we measure how long it takes to copy a sizable workload.

Most importantly, we spend a ton of time simply using each all-in-one desktop for everyday activities. We watch movies, do work, play games, and blast music on the speakers, all to get a better sense of which ones are worth your money.
