Apple’s new iMacs see significant performance increases over predecessors, benchmarks reveal

“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.”

iMac now delivers up to two times faster performance for a wide range of computing tasks.

“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!

      1. No way is this “good enough” for any users. Worst part of the iMac my parents bought last year ’cause we thought it was good enough for them. The whole machine seems more sluggish than needed, even for simple emailing and other tasks. No excuse nowadays. May as well throw in a 2400bps modem as well.

    1. Agreed! Writing this on a iMac (20-inch, Mid 2007). This is the first replacement that seems like a decent investment, as long as I opt for that Vega. Still want to see what might be announced at WWDC though. Waited this long, what’s a bit longer?

    1. This video makes excellent points. This is why Apple has lost so much respect since Cook took over.

      Apple desperately needs to completely overhaul the entire Mac lineup and deliver the superior experience and lifetime value again. The current model options reek of screwing over the buyer with cheap bean counter product spec and design decisions.
