How Much Do All-in-One PCs Cost?

All-in-One PCs run the gamut from affordable to premium pricing. Budget-friendly systems can be found for less than $1000, but will generally be limited to full HD resolution displays and low-powered Celeron and Pentium processors. Premium desktops can cost $2,000 or more, and boast 4K displays, the latest Intel Core i7 processors and discrete graphics cards from Nvidia and AMD.

Since these units are always plugged in, you might want to also invest in a good surge protector to make sure your all-in-one stays in good shape.

How We Test All-in-One PCs

Every all-in-one we review goes through a variety of benchmark tests in Purch Labs 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 20,000 names to addresses. To evaluate each system's hard drive speed, we measure how long it takes to copy 4.97 worth of files.

If an all-in-one has discrete graphics, we run it through many of the same benchmarks we use for gaming PCs. That includes 3DMark Fire Strike, as well as the built-in benchmark tools of games like Rise of the Tomb Raider, Hitman and Grand Theft Auto V. If an all-in-one is made to support virtual reality, we'll also run the SteamVR Performance Test.

Most importantly, we spend a ton of time simply using each all-in-one PC 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.
