M3 iMac Reviews: Impressive Chip Performance but Lightning Accessories Disappoint

by

Last week, Apple updated the 24-inch iMac, with the headline upgrade being the M3 chip for significantly improved performance. Other new features include Wi-Fi 6E, Bluetooth 5.3, and up to 24GB of unified memory.

iMac M3 Blue Feature

The new iMac can be purchased from the Apple's online store, with prices starting at $1,299. Apple began accepting orders on October 30, and new ‌iMac‌ will begin arriving to customers and launch in stores on Tuesday, November 7.

Ahead of time, the first reviews of the laptops have been shared by select media outlets and YouTube channels, and we have rounded up some of them below.

Written Reviews

TechRadar's Matt Hanson pointed out the ‌iMac‌'s continued use of Lightning ports on its Magic Keyboard, Magic Trackpad, and Magic Mouse:

Sticking to the same design also brings back some old frustrations, such as the charging port on the bottom of the Magic Mouse, which means you can't use it while it's charging, plus a reliance on the increasingly obsolete Lightning connection for charging all of the peripherals, rather than getting with the times and using USB-C.

TechCrunch's Brian Heater downplayed the significance of the continued use of the Lightning port, but emphasised that it was time for Apple to move on:

Apple's desktop accessories are one of the few remaining vestiges of a connector that's past its prime. It largely won't bother you. There's less daily wear, as most people don't plug and unplug their keyboards and trackpads at the same rate they do their phones. Also, you're probably not going to get pocket lint jammed in there. Still, it's time for to Apple rip off the Band-Aid off, once and for all.

Early Geekbench 6 benchmark results indicated that the M3 chip is up to 40% faster than the M1 used in the previous ‌iMac‌ from 2021.

Digital Trends's Luke Larsen on the performance improvements delivered by the M3 chip:

Moving from the M1 to the M3 is a big jump. Even if you think the performance changes between each individual generation aren't too exciting, skipping one adds up to a noticeable difference.

When you look at Cinebench R23 scores, the M3 is a whopping 20% faster in both single-core and multi-core. That's massive. It means no matter what the strenuous task is, the M3 iMac will be at least 20% faster. A good example is a simple video encoding test in Handbrake. The M3 iMac encoded the same video to H.265 27% faster than the M1 iMac.

It shows how far Apple has taken these chips in just a few generations, especially on the GPU front. I was sent the 10-core GPU model, and with the inclusion of Dynamic Caching, this little iMac is a pretty solid little engine for graphics. In the Cinebench 2024 GPU test, it was 35% faster than the M1 Pro in a 14-inch MacBook Pro despite having six less GPU cores. Meanwhile, the M3 iMac beats the M2 Pro in the Mac mini by 20% in this same graphics test. Again, I think you can credit Dynamic Caching for doing a lot of the heavy lifting in that comparison.

The M3 chip is among Apple's first 3nm chips. The M3 chip features eight CPU cores like the M1 chip, but it now offers an eight- or 10-core GPU, rather than the seven- or eight-core GPU of the ‌M1‌. It also features a 4.05 GHz CPU clock speed, up from 3.20 GHz on the ‌M1‌ chip, more memory bandwidth, support for AV1 decode, and a new GPU architecture with Dynamic Caching, hardware-accelerated ray tracing, and hardware-accelerated mesh shading.

Tom's Hardware's Brandon Hill on the 2023 ‌iMac‌ as a whole:

The iMac has always been a reasonably economical system for Mac users who want "just the basics" in an everyday computer. The screen is large, bright, and colorful. The minimalist design blends in with just about any décor (and you can choose from various colors to match), and the new Apple M3 chip provides a big jump in performance compared to the M1 model that debuted in 2021.

Unfortunately, there are quite a few "gotchas" here. While the $1,299 starting price is enticing, you're saddled with just 8GB of unified memory and a 256GB SSD. That's hardly enough to futureproof the iMac. A simple upgrade to 16GB of memory costs a staggering $200, while storage upgrades are equally pricey.

If you want Gigabit Ethernet, that's a $30 upcharge, and you only get two Thunderbolt 4 ports on base systems. You must spend at least $1,499 to get two Thunderbolt 4 ports and two USB 3 ports.

Apple's iMac is an excellent all-in-one macOS machine, though it's in need of a rethink when it comes to its pricing and available configurations.

2 ports on a desktop. What a joke.

I really wonder what Apple does all year when virtually every product line is just minor updates, the entire iPad lineup is just languishing, and they can't even be bothered to update lightning accessories to go along with their Mac updates.

I guess the USB-C Apple pencil took up all their bandwidth.

I’m not going to watch them but I’d be surprised if even one YouTuber has a single negative thing to say about the Lightning ports, the base configuration (8/256) or the number of ports.
Luckily there’s people like Marques Brownlee who never shy away from being honest instead of praising everything into high heaven.

Most YouTubers didn't agree with keeping Lightning past 2021, let alone 2023. This is ridiculous and impossible to understand from Apple. Not like it was a feat of engineering to accomplish, and not like they didn't have enough time either.

They should really have upped the price by $125 and included 16 GB as a base config.

Although I find 256 GB quite ridiculous, I think it's OK for most people, but if you're a developer, I did try a 256GB before, and I had to sell this Mac. It's simply impossible to use Xcode with such a limited amount of storage.
It’s not so much that it starts at 256, it’s that it’s $200 to take it to 512 and $400 to take it to 1TB. And that that’s a single 256GB module so it’s half the storage throughput of the $200 upgrade.
