2021 24-Inch iMac Or 2020 27-Inch iMac: Which Device Is Right For Your Needs?

2021 24-Inch iMac Or 2020 27-Inch iMac: Which Device Is Right For Your Needs?

It’s safe to say that Apple blew us all away when the 24-inch iMac was revealed at their 2021 Spring Special Event. Boasting the M1 chip and seven different colour choices, it’s definitely an attractive option for many. Yet, the question on most enthusiast’s lips remains: is it better than the 2020 27-inch iMac?

Ultimately, it all depends on your business requirements. So, to make it a little easier, we’ve compared the two devices to help you figure out which one’s right for your needs.


Let’s start with the aesthetics. A key selling point for the 24-inch iMac is its slim design. It’s made the device significantly lighter, which is helpful if you need to move it around.

Yet this does have a downside. Being 24 inches (or 23 on the diagonal, if you want to get technical) means the screen size is less than the 27-inch model. Therefore, if you need to see slightly more on your display, it looks like the latter is your best bet.

As for resolution, the 24-inch device is 4.5K and 218 pixels per inch. This insane number of additional pixels makes it one of the only 4K standalone displays of this size, placing it on par with the 5K 27-inch iMac, which has the same amount. 


In terms of performance, the 24-inch model has taken single-core to a whole new level. It’s over a third (37%) faster than the 27-inch device, and even quicker than the iMac Pro.

That being said, when it comes to multi-core performance, the 27-inch version wins. Though it’s worth noting that the 24-inch isn’t far behind thanks to the M1 chip, which consumes significantly less power in contrast to Intel processors.

So, if you’re using your iMac for day-to-day tasks and need super speedy web-browsing capabilities, we’d say the 24-inch device is perfect. It won’t require multi-cores and will definitely boost your productivity. If you’re doing any sort of creative work on the other hand, the 27-inch iMac is the better option.


Many have a qualm with the 24-inch iMac’s lack of ports. Opt for the base model, and you get three connection ports (two USB-C/Thunderbolt 4 combination ports, and a 3.5mm headphone jack). Upgrade, however, and you gain another two USB-C ports along with a Gigabit Ethernet port. 

Yet there’s still no USB Type-A port (which the majority of users require) or SD card reader, meaning you’ll likely need to purchase an adaptor. That’s why the 27-inch device is favoured – it’s got ports aplenty! In addition to what a 24-inch upgrade would bring, you get an SD card reader and four standard USB ports.

Likewise, if you’re wondering about external screen support, we’d say the 27-inch version wins this round too. It can support an extra two screens at up to 4K resolution, or one screen up to 6K. The 24-inch iMac supports just one screen regardless of the resolution.

Other features

As for other functionalities, whilst both come with a 1080p Full HD, the 24-inch takes the edge through its M1 processor, which offers enhanced image processing. This is ideal if you’re a creative business, or if you simply like to make a lot of video calls. It also has a better webcam, improved sound quality, and a keyboard complete with Touch ID.

Which Mac should you lease?

Now you’ve had the lowdown, all that’s left to do is select the iMac that’s right for you. The 24-inch certainly offers value for money through its 4.5K design, efficient M1 chip, colour choices and SSD performance, and is ideal for boosting everyday productivity. Yet if you need better graphic or CPU performance, the 27-inch could be the preferred choice.

Whatever you decide, both devices are premium, so this will be reflected in the price tag. If purchasing outright is an issue for your cash flow, you’ll be pleased to know there is another way. Through Lease Loop, you can spread these payments out over time.
