What else does the top-of-the range 21.5in i Mac offer that the mid-range model doesn’t?

Apple sells six different i Macs in two different sizes.

The size is the most obvious difference - either you choose a model with a 21.5in or a 27in display (measured diagonally).

There are a few reasons why we would dissuade you from doing so.

First of all it not have the has a 21.5in 4K screen that the other 21.5in i Macs offer.

This means there will be more detail visible in photos and movies.

The entry-level model also only has a dual-core 2.3GHz processor, with all the other i Macs offering 3GHz or more quard-core processors.You're other option is to spend a little more and buy the next i Mac model in the series. Here you get that 4K display, a quad-core processor, and a Radeon Pro graphics card.This model does still lack some features that you might find useful though.The other thing letting this i Mac down is the fact that it is the only one with an integrated graphics card - Intel’s Iris Plus Graphics 640, which is incorporated onto the processor.All the other i Macs have superior, discreet graphics cards from AMD which are better suited to games and other graphic intensive operations.The screen on the entry-level i Mac is LED-backlit, shows ‘millions of colours’ and is capable of 1920x1080 resolution.
