Apple in March introduced a refresh for its 21.5 and 27-inch 4K and 5K iMac models, which did not receive an update in 2018. The new iMac models feature the same design as the previous models, but have upgraded internals, including 8th and 9th-generation Coffee Lake processors from Intel.

In our latest video, we checked out the 27-inch 5K iMac with 16GB RAM, a 512GB SSD, Radeon Pro Vega 48 graphics, and the high-end 3.6GHz 8-core 9th-generation Core i9 Coffee Lake processor.


Apple hasn't updated the design of the iMac for six years. The slim unibody design that we're familiar with was first introduced in November 2012, and since then, there haven't been any design updates (with the exception of some display changes and port refreshes), which is a bit disappointing.

The 2019 21.5 and 27-inch iMacs continue to feature a slim 5mm display, aluminum stand, aluminum border at the bottom of the machine and relatively thick top and side bezels.

Both iMac sizes feature two Thunderbolt 3 USB-C ports, four USB-A ports, an SD card slot, a headphone jack, and an Ethernet port, with support for one 5K display or two 4K displays. On the 27-inch model, RAM is user upgradeable through a slot in the back of the machine, so upgrading the RAM more affordably after purchase is an option.

The specific model that we tested uses Apple's highest-end iMac processor, the 9th-generation 8-core version from Intel. It's outfitted with 16GB RAM, a Radeon Pro Vega 48 graphics card, and 512GB of storage, making it a higher-end option priced at $3,449 that's ideal for creatives and professionals who need a lot of processing and graphics power.

For work like video editing, intensive photo editing, 3D modeling, and other tasks, you're going to want the best processor and graphics card you can get as these elements are not upgradeable after purchase.

Based on benchmarks, Apple's new 2019 iMac models offer significant speed improvements over the prior 2017 models. Multi-core performance on the machine we tested is up to 66 percent faster, and while single-core gains aren't quite as impressive, it's still approximately 6 to 11 percent faster on average.

This particular high-end iMac with 8-core chip is actually comparable to the 2017 iMac Pro with a 10-core chip. In real-world testing, performance was impressive and the iMac was more than capable of handling our video editing workflow.

Whether or not the 2019 iMac is worth the upgrade depends on your current machine. If you're using a much older model you're going to see significant speed improvements with the latest processors, but compared to something like a 2017 iMac, it's probably not worth shelling out the extra cash at this time because the processors are the bulk of what's new.

The 27-inch iMac that we tested is ideal for system-intensive workflows, but if you just need a machine for browsing the web, light photo editing, sending email, and other tasks, one of the more affordable 27-inch machines or even the smaller 21.5-inch iMacs will be a better pick.

What do you think of Apple's 2019 iMac refresh? Are you picking up a new machine? Let us know in the comments.

I saw the headline "8-core" and for a second I was excited that perhaps there was some new unannounced iMac model, but then looking at the photo, it immediately killed the excitement.

Those big. fat. bezels. In 2019.

Compared to new crops of monitors with 0.3" bezel, iMac's 1" bezel and 5" chin are almost humorously large. I will take thicker iMac with slimmer bezel any day. Come to think of it, I don't think any consumers wish for thinner iMac.

One area where Apple is trying to maintain their ecosystem! Some hope at least. This is what Apple was about, filling all the niches that are necessary so can have your work machines linked to your portable devices, phones, iPads and not have to leave and get a PC for work and then have a broken ecosystem.

I hope they can make an amazing Mac Pro - and then I don't have to buy some HP box and screw up all my syncing.

Pretty sure you’d be the same person crying “form over function” if they released a new look iMac, but with the same specs at a higher price.

It’s a very capable machine at a reasonable price for an AIO. Why can’t that be enough?

Still one fan though? That alone would have me worried. The cooling system on the iMac Pro is much better designed.
The iMac Pro also has a 140 Watt CPU, a higher wattage GPU, four thunderbolt 3 ports and a 10Gb Ethernet port. It’s a lot higher thermal load. But yeah it’s nice, though you lose the easy RAM upgradeability.

I'm planning on getting a new MacBook Pro this year, but only if they fix the thermal throttling and the keyboard issues...

Don’t worry—they’ll release one without bezels but will kill the USB A ports and that will drive people nuts.

Does the bezel REALLY matter to you that much on a 27" display? Honestly I think you're really overreacting.

Is VEGA 48 worth it as an upgrade? Will be using it for 360' video, RAW 30+MP photo editing and maybe VR in the distant future. $500 is a lot of money for an incremental upgrade.

I don't care so much about the bezels (it is 100% cosmetic), but I think they could've added some biometrics, increased the resolution of the webcam, and maybe some day incorporate 120 Hz panels.

I know the current design is "tried and true", but I think there is some room for improvement in the design apart from cosmetic changes.

Bezels on a phone or tablet is one thing because it allows for a much larger display in a smaller form factor or a smaller, lighter form factor for the same size display (like the 12.9" iPad Pro). For a desktop it barely matters.

The only small reason I can see for needing smaller bezels on a desktop is for tiling multiple displays. But even that isn't seamless and hardly makes a difference. Someday when they do redesign they will put in smaller bezels just because, but did it occur to anyone that if they make the bezels smaller it would make the volume smaller and negatively impact the cooling? Maybe they are waiting until they can include a larger 6K display with larger bezels or for Intel (or Apple) to release more energy efficient CPUs on a smaller 10nm/7nm process.

Nothing about thermals or fan noise?
Max Yuryev addresses thermals and fan noise in (his video)

Jason Snell also has a top-end 2019 model on loan from Apple and he noted that the fans ramp up slower and their peak RPM is lower than the 2015 and 2017 models with i7s, though his base iMac Pro is quieter under similar load. I have heard other reports of the 2019 not running as loud under load.

So it sounds like the 2019 model's thermals may not be as stressed as the 2017. Intel solders the heatspreader on the i9-9900K so this improves the ability of the heatsink to dissipate heat compared to the older i7's using thermal interface material.

Also, these i9's might be "TDP-locked" (for lack of a better term) to 95W no matter the load whereas the i7's could clear 100W or more even though their official TDP is 91W. This 95W limit is used by some SFF vendors due to the lower cooling capacity of their cases so it would make sense for Apple to adopt it for the iMac.

And Apple might have modified the fan itself to move more air at a lower speed (we'll know once we see the iFixit teardown).

Your buying the computer for it's power - not as a furniture :)

Testing shows good thermals and low fan noise, surprising due to the i9 - 8 core chip.

Design was important to Steve. The original iMac was as much about design as it was about functionality.

"The back of this thing looks better than the front of the other guys, by the way," Jobs said as he detailed the thought that went into its design.

Now PCs look better than the fat bezel 2019 iMac.
