2019 iMac performance ranges from 5% to 66% increase over 2017 model

Geekbench’s John Poole shared a series of 2019 iMac benchmarks, the new benchmarks show the impressive gains of the Intel 8th and 9th-generation Coffee Lake chipsets.

The highest-end iMac earned a single-core score of 6157 and a multi-core score of 32293, compared to the 5864/1971 single and multi-core scores of the equivalent high-end machine.

The biggest boost in the new 2019 iMacs was the 27-inch Core i9 processor which has a multi-core score up 66 percent. The rest of the 27-inch 5K models had multi-core gains of between 43 percent and 49 percent and a range of 6 percent to 11 percent for single core.





The 21.5-inch models didn’t have quite as impressive gains as the 27-inch did, but still 5-10 percent higher in single-core and 10-50 percent higher in multi.
