iMac 27 inches Design.

As you know that 27 inch iMac has gone through several updates but nothing about the exterior has changed since the 2014 release. 

Its frame features 5mm tapered casing and a hump on that back that is large on the back. This big hump houses the internal components and large ching under your iMac’s screen.

Despite a pixel dense screen and even powerful chipset and graphics, the cooling system has not changed yet and also the slotted exhaust holes run across the bottom of the screen. 

All the power cables and ports connect in the back and there is a hole which allows for cable management.

But, one of the things you can say that is unfortunate is the design which prevents users from accessing the ports easily and makes the connection temporary. Because of this, it is also harder to hide or manage.

iMac 27 inch Processor.

iMac 27 inch: Processor.

By default, the latest 27 inch iMac comes with the 10th generation intel i7 and i5 chipsets.

The base model contains Radeon Pro 500 Series GPU. It is an advantageous improvement over the previous generation based GPU. 

If you wish to have a powerful graphic machine without jumping up to much more expensive iMac Pro then upgrade your 27 inch iMac to Radeon Pro 5700 XT .

Upgrade Path.

There is a rear door below the power cable in the 27-inch iMac that allows users to change or add the installed RAM. users can use cheaper third party solutions and can upgrade the RAM up to 128GB.

Internal storage is fixed to the logic board and cannot be upgraded or removed by the user. Storage is available in 8TB, 4TB, 2TB, 1TB and 512GB configurations and the 8T and 4TB versions connect extra storage with the help of expansion mount and cables.

Even if the user soldered in new storage or detached the storage, the system will automatically reject it as the storage and the logic board are paired in hardware at installation.

As mentioned above, there are two THUNDERBOLT 3 ports in 27-inch iMacs, that allows for two 6K monitor connections. It also includes Pro Display XDR. 

This also allows for fast speed data transfer, that means the external memory is limited only due to its data transfer speed as if it is hard wired.

Users can attach to the external GPU via Thunderbolt 3 if needed more graphic powers. Companies like Blac Magic are pros in making powerful GPUs. It can massively boost up a Mac’s performance. You don’t have to buy a new machine for it.



The iMac updates starts with 4GB of GDDR6 memory with Radeon Pro 5300 graphics.

It can also be upgraded to Radeon Pro 5500XT with 16GB or 8GB of memory if you need much improved graphics.
