iMac vs Mac Mini: Which Desktop Mac Should You Buy?


If you're looking for a desktop Mac, rather than the mobile charms of the MacBook, MacBook Air or MacBook Pro, there are currently two obvious choices in the Apple range: the iMac and Mac mini. In this article we look at how they compare for features, specs and value for money, and help you decide which is the right choice for you.


As you might expect for a device that doesn't come with a display, the Mac mini starts off a bit cheaper than its glass-wielding sibling. There are two stock options, with the base 3.6GHz Quad-Core model that features 128GB of PCIe-based SSD storage and 8GB of RAM costing £799/$799, and the 3.0GHz (Turbo Boost up to 4.1GHz) 6-Core, that boasts a 256GB SSD and 8GB of RAM available for £1,099/$1,099.

Either can be configured up to a whopping 64GB of RAM (for an equally whopping £1,260/$1,260 additional cost) and 2TB of PCIe-based SSD storage (which will set you back another £1,440/$1,440).

The iMac range has a few more strands, due to the different displays on offer. Those happy with a 21.5in panel can opt for either of the following:

  • 2.3GHz dual-core 7th-gen Intel Core i5, 8GB RAM, 1TB HD, 1920x1080 display, for £1,049/$1.049
  • 3.0GHz quad-core 7th-gen Intel Core i5, 8GB RAM, 1TB HD, Retina 4K 4096x2304 P3 display, for £1,249/$1,249
  • 3.4GHz quad-core 7th-gen Intel Core i5, 8GB RAM, 1TB Fusion Drive, Retina 4K 4096x2304 P3 display, for £1,449/$1,449

Should you prefer the larger 27in display, these are the options:

  • 3.4GHz quad-core 7th-gen Intel Core i5, 8GB RAM, 1TB Fusion Drive, Retina 5K 5120x2880 P3 display, for £1,749/$17,49
  • 3.5GHz quad-core 7th-gen Intel Core i5, 8GB RAM, 1TB Fusion Drive, Retina 5K 5120x2880 P3 display, £1,949/$1,949
  • 3.8GHz quad-core 7th-gen Intel Core i5, 8GB RAM, 2TB Fusion Drive, Retina 5K 5120x2880 P3 display, £2,249/$2,249

All are configurable in different ways, offering extra storage, RAM, and processor upgrades via the Apple store.

(There's also the iMac Pro available for £4,899/$4,899, but that's a very expensive and niche product that will most likely only appeal to professionals using it for work, so we won't go into it here. If you want to see what this incredible powerhouse can do, then read our full iMac Pro review.)


As you can see from the price list above, there are far too many options to include in a comparison review without the whole thing descending into a complicated spreadsheet-style affair. So, for the sake of clarity we will restrict ourselves to the entry level offerings of either model. Just be aware that the other variants are available if you want more power, different screen sizes, storage options and so on.

Anyone who has seen an iMac in the last few years will instantly recognise the slim, all-in-one design of the current model. Under the expansive display is a brushed aluminium 'chin' bearing the Apple logo, and around the back is a curved bulge that contains the bulk of the hardware as well as an array of ports and the built-in stand.

If you're looking for a complete system in an attractive package, then the iMac is one of the best you can currently buy. The elegant, simple look is one that still holds its own, but with little change since the design was first unveiled back in 2012, Mac users wouldn't be unreasonable to hanker after a new aesthetic. Even a black chassis like the one found on the iMac Pro would be a start.

Keeping with the 'if it ain't broke' motif, the Mac mini (reviewed here) is also identical to its predecessor in terms of construction, with the classic 19.7cm x 19.7cm x 3.6cm aluminium chassis making it a perfect fit for smaller desks or even rack mounting.

Again, you'll find all of the ports situated at the rear, but as this is a Mac mini you won't find a display, keyboard, mouse or trackpad, as none are included in the package. Apple did make one external alteration when revamping the mini in 2018, changing the colour from the plain aluminium to Space Grey, which does look much cooler.

Features and Specifications

Apple hasn't updated the iMac range since June 2017, and as a result the internals are now ageing in comparison to its rivals. The Intel chips are 7th-generation Kaby Lake, while the Mac mini uses 8th-generation processors, storage is on hard-disks rather than the much faster SSDs in the mini (although this does mean that capacity on the iMac is a lot larger) and the base model doesn't feature the 4K display that adorns the other 21.5in device in the range.

That being said, the performance and features of the iMac 21.5in will be perfectly acceptable for general computing duties such as working on documents, browsing the web, streaming content, creating music on GarageBand, or editing home videos on iMovie.

The HD panel that Apple fits in the iMac is also a nice one, with crisp definition and warm colours, meaning you'll only bemoan the lack of 4K if you're already used to viewing a display of that quality.

There's no such deliberation to be made about the Mac mini display, as you have to bring your own. But when you do so the unit can support up to 5K resolutions, and also has the option to run three 4K screens simultaneously.

Internally, the Mac mini is a snappy performer, with the 3.6GHz Quad-Core Intel Core i3 proving 5x times faster than its predecessor. Now, to be fair, the previous model was four years old and somewhat underpowered to begin with, but the switch to 8th generation chips definitely brings the speeds up to modern standards.

This is aided by faster 2666MHz DDR4 RAM (the iMac has 2133MHz DDR4) and the PCIe-based SSD, which zips along at a much higher clip than the spinning hard drive on the iMac, making the system generally feel more responsive when launching apps and retrieving information.

You pay for this rapidity with a drastically reduced amount of storage. 128GB is small for laptops these days (or even phones!) and on a desktop device it's minuscule. If you want to store any movies, along with a music collection and a few larger applications like Logic Pro X, then you'll be running out of space almost before you begin.

This can of course be augmented by the addition of external hard drives via the Thunderbolt 3/USC-C or USB A/3.0 ports, but that adds more to the cost, which is a constant theme with the mini.

In the past the Mac mini was always attractively priced, so when you factored in the purchase of a display, keyboard, trackpad/mouse, speakers, cables and such, it was still a good deal for the consumer. 2018's model raised that entry price significantly, so the £800/$800 starting point quickly escalates to way above £1000/$1000, especially if you buy Apple products.

For example, we configured a setup on the Apple Store which included the base Mac mini, a 4K HDMI cable, Magic Keyboard with numeric keypad, plus a Magic Trackpad 2 and the total came to £1,126.95/$1,126.95, all of which is still without a display and speakers.

Even choosing the cheapest option from our recent Best Mac monitors & displays roundup, the Dell S2718H, added a further £272, and that left us with only HD rather than 4K abilities. So, for around £1400/$1400 the Mac mini is far from affordable for most people.

Of course, if you have previous hardware then this price comes down, but it's worth considering the real cost when comparing the Mac mini to its seemingly more expensive counterpart.

Here's a breakdown of the full specifications for both models.

The new Mac mini is faster than the iMac in all departments thanks to its updated hardware, but the price hike makes it harder to recommend than in previous years. Once you factor in the required peripherals the total cost can be well beyond the iMac, especially if you head down the 4K route.

It's also difficult to point towards the current iMac, as the internals are getting too dated to justify the current asking price. Oddly, we'd advise you to buy neither at the moment, and instead wait to see what Apple unveils for the iMac in 2019, as the revamp could give the new mini a better run for its money.
