The iMac lineup
The Apple iMac lineup was last updated in March 2019 and includes models with a 21.5-inch and 27-inch display. The least expensive iMac begins at $1,099, with the most costly model starting at $2,299. Price is largely affected by differences in display quality and size, processor speed, RAM, and the type of hard drive and graphics card.
The display size
The 21.5-inch (diagonal) iMac is available in two display flavors. The least expensive features an LED-backlit display with 1920‑by‑1080 (HD) resolution. All other available 21.5-inch models include a Retina 4K display with 4096-by-2304 resolution, 500 nits brightness, and Wide color (P3).
All 27-inch models come standard with a Retina 5K display, 5120‑by‑2880 resolution, 500 nits brightness, and Wide color (P3).
i5 vs. i7 processor
The current iMacs come with a choice of processors, each better than the next, of course. When looking at processors, keep in mind its number of cores, which are the brain of the CPU. These cores receive instructions and perform calculations: the more cores, the better the performance.

- 3.7GHz 6‑core Intel Core i5 (Turbo Boost up to 4.6GHz), configurable to 3.6GHz 8-core Intel Core i9 (Turbo Boost up to 5.0GHz)
Upgradable RAM vs. non-upgradable RAM
In recent years, Apple has made it nearly impossible to update its computers after purchase. One of the few exceptions is the 27-inch iMac, which still offers users the ability to replace and upgrade RAM. The 27-inch model comes with at least 8GB of RAM, which you can expand to 16GB, 32GB, or 64GB of RAM.
The 21.5-inch iMac, regardless of model, comes with non-upgradable RAM. It ships with at least 8GB of RAM, which you can increase at the time of purchase to 16GB or 32GB.
Hard drive vs. Fusion Drive vs. SSD
When it comes to purchasing storage for your iMac, the choice comes down to Fusion Drive vs. SSD, although you can still buy a traditional hard drive on the least expensive model.
As Apple explains, SSD storage delivers improved performance compared to a traditional hard drive, the speed you'll notice when you start up your iMac, launch an app, or browse your photo library. Because SSD storage uses no moving parts, there's no noise.
By contrast, a Fusion Drive combines the speed of SSD storage with a high-capacity hard drive. By doing so, the Mac intelligently manages what goes where using the SSD storage for files you access frequently and keeping the rest of your digital life on the roomier hard drive.
Price-wise, SSD costs much more than Fusion, but many argue that it's well worth the price difference.
Radeon vs. Iris
