There's nothing like an Apple iMac to bring excitement and productivity into your home. A popular choice for families and professionals alike who are looking for an all-in-one computer solution, the iMac comes in two sizes, 21.5-inches, and 27-inches. Our favorite for 2020 is the iMac 5K (2020), which is packed full of terrific features with a huge 27-inch display. There are other models worth considering depending on your needs.

Featuring an aluminum and glass enclosure with a five millimeter-thin profile, the best iMac, the iMac 5K ships with a matching Magic Keyboard and Magic Mouse 2. Apple offers an excellent lineup of three 27-inch iMac versions, starting with the entry-level model that includes a 3.1GHz 6-Core 10th-generation Intel Core i5 processor with Turbo Boost up to 4.5GHz, 8GB 2666MHz DDR4 memory, configurable up to 128GB, Radeon Pro 5300 with 4GB of GDDR6 memory, and 256GB SSD storage.

For more money, you can increase your RAM, processor, and storage. There's also an all-new option to get nano-texture glass instead of the standard glass.

The latest 5K iMac was released in August 2020 and includes faster Intel processors up to 10 cores, double the memory capacity, next-generation AMD graphics, superfast SSDs across the line with four times the storage capacity, a 1080p FaceTime HD camera, higher fidelity speakers, and studio-quality mics.

iMac 5K

Look at that display!

Reasons to buy

Beautiful Retina 5K 5120-by-2880 P3 display with True Tone
1080p FaceTime HD Camera
2020 models are here!

Reasons to avoid

Price can rise quickly with add-ons
8GB of memory might not be enough

Forget 4K, when you can have 5K. Great internals and a robust display in one package.

Best iMac Entry Level: iMac 4K (2019)

The iMac 4K is only available with a 21.5-inch display, which is something to consider before making a purchase. The least expensive model offers a 3.6GHz quad-core 8th-generation Intel Core i3 processor with 8GB 2400MHz DDR4 memory, configurable up to 32GB, 1TB hard drive, and Radeon Pro 555X with 2GB of GDDR5 memory. The more expensive version includes a 3.0GHz 6-core 8th-generation Intel Core i5 processor and other extras.

Like other Macs, the iMac 4K ships with macOS Catalina, which includes an all-new Music app alongside apps for Apple TV and Podcasts. The update is also the first to include Mac Catalyst, which allows developers to move iPad apps to Mac with ease.

When looking at the 21.5-inch iMac lineup, avoid the least expensive model unless you're buying it as a secondary device (see below). It's the one without 4K. The iMac 4K was last updated in March 2019, which means a hardware update could arrive soon.

Budget choice

Reasons to buy

Less money than 5K versions
Two main choices for 4K

Reasons to avoid

Can't buy 4K 27-inch iMac
Could soon get updated

You get Apple's impressive 4K Retina display on this iMac model. Inside you'll find less expensive parts than the 5K option.

Best iMac Secondary: Non-Retina iMac (2019)

This is Apple's least expensive iMac, and the only one that doesn't have a 4K or 5K display. Instead, it offers a 1,920‑by‑1,080 resolution, making it a great choice as a secondary iMac in your home. Inside, you'll find a 2.3GHz dual‑core Intel Core i5 (Turbo Boost up to 3.6GHz), 8GB of 2133MHz DDR4 memory, and 1TB (5400-rpm) hard drive.

If you decide to purchase this model, don't upgrade its memory or storage. Instead, buy the entry-level choice above.

Least expensive iMac

Reasons to avoid

Don't upgrade the specs on this
Could be nearing end-of-production

Whether for your younger kids or as an extra computer, this iMac is nice to have and available at a great, low price.

Best iMac for Pros: iMac Pro (2017)

First introduced in late 2017, the iMac Pro includes an 8-, 10-, 14-, or 18-core Intel Xeon processor, 27-inch (diagonal) Retina 5K display, AMD Vega graphics, up to 256GB ECC memory, and 10 Gigabit Ethernet. In other words, this is one powerful machine!

Geared towards highly professional creatives, the iMac Pro can easily cost you five figures, depending on your configuration. Only buy this model if you need the expanded resources, like the color black, and a no-brainer, have a budget to support the purchase.

The most significant issues facing would-be iMac Pro buyers is two-fold. First, the product hasn't been updated in three years, which makes a refresh likely. Second, with the Mac Pro (see below) now on the market, the choice isn't nearly as simple anymore.

iMac Pro (2017)

The one for massive projects

Reasons to buy

Lots of customization
Memory up to 256GB
Only iMac that comes in black

Reasons to avoid

Extremely pricey
Not for most buyers
Hasn't been updated since 2017

Get your boss to buy you this one -- or get it yourself if you're the boss!

Our choice for Best iMac

For 2020, we consider the iMac 5K (2020) the best iMac of the year, which includes lots of great features for everyone in your household, and most professional buyers.
