Intel's Coffee Lake Chips Bring Significant Speed Boosts to 2019 iMacs

Geekbench's John Poole this afternoon shared a series of 2019 iMac benchmarks, giving us a look at the performance boosts offered by Intel's 8th and 9th-generation Coffee Lake chips.





All of the new 27-inch 5K models offer superior performance compared to their 2017 counterparts, with single-core performance up an average of 6 to 11 percent and multi-core performance up 43 to 49 percent for six-core models. The higher-end models with 3.6GHz 8-core Core i9 chip offer the biggest boost in multi-core performance, with speeds up 66 percent.

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.

Even the base model 2019 27-inch <!---->iMac<!----> with a 3.0GHz 6-core 8th-gen chip saw notable gains, earning a single-core score of 5222 and a multi-core score of 20145, compared to the 4767/13682 scores the low-end 2017 models earned.





These chips are two years apart, so it is no surprise that even the mid-level chips are outperforming the higher-end chips from 2017.





6-core and 8-core chips in the 27-inch models are now competitive with the 2017 iMac Pro models with 8 and 10-cores. The high-end 8-core <!---->iMac<!----> offers 16 percent higher single core performance and just 10 percent lower multi-core performance than the 10-core <!---->iMac Pro<!---->.





Gains are more modest for the 21.5-inch 4K <!---->iMac<!----> models, but still significant. Single-core performance is up 5 to 10 percent, while multi-core performance has increased by 10 to 50 percent.

As Poole points out, the performance gains in the 2019 <!---->iMac<!----> models are due to higher frequencies and core counts as the underlying architecture hasn't been updated.





Poole says that while there's a significant boost when it comes to multi-core performance in the new iMacs, along with a decent boost in single-core performance, the increase isn't enough to "justify upgrading from a 2017 <!---->iMac<!---->."





Apple's newest <!---->iMac<!----> models were announced last week and have been arriving to customers this week. Aside from Intel's new 8th and 9th-generation Coffee Lake chips, Radeon Pro Vega graphics options, and faster RAM, there have been no other improvements to the 2019 <!---->iMac<!----> models.
