2020 iMac benchmarks show substantial speed boost

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 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 chip 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, achieved an 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 37,664 and 32,282, respectively. That gives the 2020 iMac a 16.6% advantage over its immediate predecessor.

The new iMac’s speed bump isn’t all about the Intel chip, either. Other features give it a performance boost as well. This year’s all-in-one makes SSDs standard (buh-bye, slow hard drives). The latest AMD graphics cards deliver “up to 55 percent faster graphics performance,” according to Apple. And the inclusion of Apple’s T2 security chip also increases the iMac’s performance for certain tasks.

The upgraded 1080p FaceTime camera, and improved speakers and microphones, are just gravy.
