The iMac M1 is nearly 60% faster than the older Intel model, according to leak

Apple’s new 24-inch M1-powered iMac will be a significant upgrade for desktop Mac owners who require more performance. The new iMac with an M1 processor outpaced its Intel-based predecessor with a performance gap nearly as wide as 60%, according to a leaked benchmark spotted by MacRumors. That represents a sizable performance jump between the models.

The new desktop was put through its paces and scored 1,729 points and 7,459 points on the Geekbench 5 benchmark utility for the single-core and multicore tests, respectively. The benchmarks arrive ahead of Apple shipping the iMac, and the scores are probably from early review samples. These Geekbench 5 scores show that the iMac is on par with the M1-powered Mac Mini and notebooks like the MacBook Pro and MacBook Air. Geekbench revealed that the iMac’s CPU is configured with an eight-core processor and a seven-core GPU, likely showing the base M1 configuration clocked at 3.2GHz.

Apple also offers higher-end iMac models with higher-tuned M1 performance, like a model with an eight-core CPU paired with an integrated eight-core GPU. The M1 iMac was introduced at Apple’s recent Spring Loaded event, and the processor is based on the ARM architecture that’s widely used in modern smartphones and tablets.

This places the base 24-inch model ahead of the 21.5-inch Intel model that it is replacing. The Intel Core i7-8700 model scored just 1,109 points and 6,014 points on the same benchmark for single-core and multicore performance, respectively. Apple’s Intel-based iMac topped out with an 8th-gen processor, so the comparison isn’t quite “Apple to apples” with Intel. A fairer comparison would pit the M1 against a 10th-gen or 11th-gen processor, but Apple didn’t use Intel’s newer CPUs on its desktop. Still, with the notable performance improvement from the M1 processor, owners of older iMacs should have nothing to worry about if they’re in the market for an upgrade.

For comparison, the top-of-the-line 27-inch model scored 1,2479 points and 9,002 points on the single-core and multicore tests, respectively, making it 25% faster in multicore performance against Apple’s M1-powered 24-inch iMac. However, the M1 is still 38% faster in single-core performance. When the M1 chip was stacked against Intel’s lower-end configurations on the 27-inch iMac, like the six-core model, Apple’s silicon beat its rival in both single-core and multicore tests.

In addition to the bolder color options, slimmer design, and the switch to the M1 chipset, Apple’s latest iMac also comes with an improved microphone array, a better FaceTime HD camera, and a new speaker system to make your video calls look and sound better.

Apple’s M1 processor is now shared on its Mac Mini, iMac, MacBook Pro, MacBook Air, and iPad Pro tablet. The company is already rumored to be hard at work developing an M2 chipset to succeed the M1, and the processor could debut in an entirely redesigned MacBook Air that’s inspired by the iMac’s new aesthetics in the near future.

I’m a laptop reviewer. Here’s why I still use a laptop from 2021

I'm pretty much always using a new laptop as my daily driver -- whichever one that I'm testing for review. And in 2023 alone, I've reviewed almost 40 machines, ranging from near-budget machines with solid performance and impressive features all the way up to innovative devices like the HP Spectre Foldable PC.

But occasionally, there's a lull in new releases, which gives me a chance to do a gut check. Which laptop do I return to as my primary work machine? To my own surprise, it's none of the flashy new releases from 2023. It's a laptop from way back in 2021 that remains my favorite. Not coincidentally, it's the only laptop I've purchased myself in years. That laptop is the first-gen Apple MacBook Pro 14, and it's held up so well against the competition that I still haven't felt compelled to replace it. Here's why.
The display continues to blow me away

A new iMac Pro could still launch. Here’s what I want from it

A week ago, a shocking report emerged: Apple apparently had no plans for a larger iMac, potentially meaning the iMac Pro was dead and buried. However, opposition voices soon emerged, and the consensus now seems to be that Apple has only ruled out the 27-inch iMac, not the idea of a larger all-in-one entirely.

In fact, just yesterday, Bloomberg Mark Gurman reiterated his previous claims that a larger iMac is still in the works. That’s an exciting rumor because I’ve felt for years that the iMac isn’t quite living up to its potential. If a larger, more powerful version really is still in development, it could be a seriously impressive device. Here’s everything I want to see from it.

Apple just dashed our iMac hopes and dreams

Apple has confirmed it has no plans to release a 27-inch iMac in the immediate future. The news comes on the same day that reviews for Apple's 24-inch iMac M3 and MacBook Pro M3 went live, with the company urging pro users who had been waiting for a 27-inch iMac update to go with a Mac Studio or Mac Pro instead.

An Apple representative confirmed that a 27-inch iMac with Apple silicon won't be arriving soon to The Verge. Apple last updated the 27-inch iMac in 2020, just a few months before Apple silicon was released to the world. It never saw Apple Silicon, instead being stuck on older Intel chips. Apple discontinued the product in 2021, eventually delisting it the next year.
