“Apple announced updated 21.5-inch and 27-inch iMacs last week,” John Poole writes for Primate Labs’ Geekbench blog. “Let’s take a quick look at the performance of the new iMacs using Geekbench 4 results from the Geekbench Browser.
“For those unfamiliar with Geekbench 4, it is our cross-platform CPU and GPU benchmark,” Poole writes. “Higher scores are better, with double the score indicating double the performance.”
“There are currently no results for the new 21.5-inch iMac with an i7 processork,” Poole writes. “I expect its performance will be comparable to the
Mac mini with an i7 processor as their processors have the same number of cores and frequencies.”
“For the new 21.5-inch iMac with i3 and i5 processors, single-core performance is up 5-10%, and multi-core performance is up 10-50%k,” Poole writes. “Since the processor architecture is effectively unchanged between the 7th generation and the 8th generation Intel Core processors, most of the increase is due to higher frequencies and higher core counts.”
“For the new 27-inch iMac, single-core performance is up 6-11%. Multi-core performance is up 43-49% for the 6-core models, and up 66% for the 8-core models,” Poole writes. “Again, the increase is due to higher frequencies and core counts, not to any architectural improvements.”
“The new 6- and 8-core iMac is even competitive with the 8- and 10-core iMac Pro,” Poole writes. “For example, the 8-core iMac has 16% higher single-core performance and 10% lower multi-core performance than the 10-core iMac Pro.”

MacDailyNews Take: The new iMacs’ single-core performance is significant, but the multi-core performance boost can be massive and even compete very well with Apple’s iMac Pro beast!
