27-inch iMac

For years, until the recent advent of iMac Pro and Mac Pro, the iMac was seen as the professional's desktop Mac. Its sizable 5K display and powerful graphics options made it powerful enough for most development and production. The 27-inch model hasn't been updated with Apple Silicon processors, but that may change soon.

The 27-inch iMac was discontinued in March 2022, but that may not be for long. Rumors indicate that Apple could announce a new iMac with high-end processors. It would have a new design similar to the 24-inch iMac with improved external monitor support and a mini LED backlight.

For now, Apple released the 27-inch 5K Studio Display. It is essentially the same display panel as the 5K iMac, but designed to look like a cross between the 24-inch iMac and the Pro Display XDR.

iMac 5K Features

Design

While the 27-inch iMac has gone through a few updates, nothing about the external design has changed since its 2014 release. The frame features a 5mm tapered casing with a large hump on the back to house the internal components and a prominent chin under the screen.

Despite a pixel-dense screen and ever-more-powerful graphics and chipsets, cooling hasn't changed, either – slotted exhaust holes run across the bottom of the screen. All ports and the power cable connect in the back, and the stand has a hole to allow for cable management.

Unfortunately, this design prevents easy access to ports, making temporary connections harder to manage or hide.

Processors

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

The base model comes with a Radeon Pro 500-series GPU, which significantly improves the previous generation's base GPU. Upgrade to the Radeon Pro 5700 XT, which is in shouting distance of the iMac Pro's Vega 56, and you will have a powerful graphics machine without jumping up to the much more expensive iMac Pro.

Upgrade path

The 27-inch iMac has a rear door below the power cable to add or change the installed RAM. Users can upgrade the RAM up to 128GB and use cheaper third-party solutions.

Internal storage is fixed to the logic board and cannot be removed or upgraded by the user. Storage is available in 512GB, 1TB, 2TB, 4TB, and 8TB configurations, and the 4TB and 8TB versions connect the extra storage via cable and expansion mount. The expansion mount isn't present in the lower storage options.

Even if users detached the storage and soldered in new storage, the system would reject it, as the logic board and storage are paired in hardware at installation.

Same body, same ports in the 27-inch iMac

The 27-inch iMac has two Thunderbolt 3 ports, allowing two 6K monitor connections, including the Pro Display XDR. These versatile ports also allow for fast data transfer speeds, meaning external memory is limited only by its data transfer speed as if it were hard-wired.

Users who need more graphics power can attach external GPUs via Thunderbolt 3. Companies like Black Magic make powerful eGPUs that can massively boost a Mac's performance without needing a whole new machine.

If you are not a fan of the included iMac stand, you can remove it and add a VESA mount. This allows for better control over the screen position because the installed stand does not offer much movement at all.

27-inch iMac Product History

2022

Apple discontinued the 27-inch iMac in March 2022 after an Apple event that announced the Mac Studio and Studio Display. The product may still be revived in the future with Apple Silicon processors.

2020

On August 4, Apple updated the iMac line to align with other Macs released in 2020. The naming scheme shifted to be more standardized to address the display size, not the resolution.

The 27-inch iMac can now be configured with a nano-texture display for an additional $500. It comes with the latest 10th-generation Intel processors and now has the T2 for added security.

These updates are expected to be the last for the classic iMac models. The next update should arrive in 2021 with a larger display and running Apple Silicon. Rumors show a 24-inch iMac is likely to hit the market first.

2019

The iMac saw a new performance update in March 2019, while in the iMac Pro shadow, it still held steady as the budget-minded pro desktop. This iMac can fill most consumers' needs with the option to go all out and add an i9 processor and new Vega graphics.

While rumors had circulated that 2019 was the year for a new iMac design, we still received the same tried-and-true 2012 model. Concerns persist that this old design will limit thermal overhead, which may necessitate a change in design.

Also, additional USB-C ports were missing in the update. The same two Thunderbolt 3 ports are present, but instead of more USB-C ports like in the Mac Mini update, it has the same 4 USB-A ports.

2017

The 2017 update was a significant one that introduced massively improved Radeon graphics options and Thunderbolt 3 spec ports.

Replacing the two Thunderbolt 2 ports, the Thunderbolt 3 ports offered much greater capabilities, such as connecting two 4K monitors or a single 5K external monitor.

2015

In 2015, Apple introduced the 21.5-inch iMac 4K with various upgrades that were passed to the iMac 5K, like new chipsets, SSD options, and the P3 color gamut.

Also of note was the launch of Apple's new peripherals, rechargeable Magic Mouse, keyboard, and trackpad, which were included in the box.

2014

In October, Apple held its 2014 product keynote with viewers hoping for some upgrades to the ill-fated 2012 Mac Pro. Instead, we got the iMac 5K, a powerful machine with a new display.

Touted as having the highest resolution of any display at the time, Apple was quick to brag about the new timing controller and display panel they had to build from scratch to make such a display work.

Offering Intel Haswell CPUs, the machine could perform tasks without issue, even at the entry level. However, the base-level 8GB of RAM struggled with some more intensive tasks, requiring users to upgrade or add RAM after the fact.

iMac 5K Pricing

The 27-inch iMac comes with a base configuration of 3.1GHz 6-core 10th-generation Intel i5, 8GB DDR4 RAM, 256GB SSD, and Radeon Pro 5300 graphics for $1,799. It can be configured with faster Intel processors up to the 10th-generation Intel i7, an 8TB SSD, up to 128GB RAM, and improved graphics with a Radeon Pro 5700 XT.

A maxed-out iMac 5K costs $8,799 and would likely perform better than the same-priced iMac Pro.

Common 27-inch iMac 5K Questions

Is 27-inch iMac 5K good for gaming?

Since macOS isn't known as a gaming platform, the iMac 5K isn't a good choice for a gaming machine. But if you already own one and want to use it for gaming, you could install Windows through Bootcamp for a decent gaming experience.
