2020 iMac benchmarks show substantial speed boost

The 2020 iMac is faster, but didn’t get a new design.

The very first benchmark scores are coming to light for the 2020 iMac that Apple unveiled Tuesday, and this computer is already showing a healthy performance increase over the 2019 version.

Expect a nice performance bump in the 2020 iMac

This is the first iMac with the tenth-generation Intel Core processors. The updated models released in 2019 used ninth-generation chips.<!– –>

A new 27-inch model running a 3.8 GHz 8-core i7 processor pulled in a 9,741 score on Geekbench 5 Multi-Core, according to Max Yuryev on YouTube. And this isn’t the fastest available — there’s also a 3.6 GHZ 10-core i9 option.

For comparison, the fastest version of the 2019 iMac, with a 3.6 GHz Core i9 processor, had a 8,292 score on that same test.

But not everyone will get a top-tier model. That’s why Macotakara did a comparison of the 2020 and 2019 versions with Intel Core i5 processors running at 3.1 GHz. The newer device scored 5,688 in Geekbench 5 Multi-Core, while the previous one scored 5,100. That’s a 10.3% year-over-year increase.

In the Compute test for these models, the scores were 37664 and 32282, respectively. That gives the 2020 iMac a 16.6% advantage over its immediate predecessor.

The new desktop Mac isn’t just about speed, though. The all-in-one makes the jump from a 4K to a Retina 5K display, there’s an upgraded 1080p FaceTime camera, and improved speakers and microphones.
