Title: Intel's Coffee Lake Chips Bring Significant Speed Boosts to 2019 iMacs Post by: HCK on April 02, 2019, 04:05:07 pm 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 (https://www.geekbench.com/blog/2019/03/imac-performance-march-2019/), 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. <img src="(http://cdn.macrumors.com/article-new/2019/03/2019imacmulticore-800x599.jpg)" alt="" width="800" height="599" class="aligncenter size-large wp-image-686862" /> The highest-end iMac (https://www.macrumors.com/roundup/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. <img src="(http://cdn.macrumors.com/article-new/2019/03/2019imacsinglecore-800x599.jpg)" alt="" width="800" height="599" class="aligncenter size-large wp-image-686863" /> 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 (https://www.macrumors.com/roundup/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. <img src="(http://cdn.macrumors.com/article-new/2019/03/2019imac4ksinglecore-800x482.jpg)" alt="" width="800" height="482" class="aligncenter size-large wp-image-686864" /> <img src="(http://cdn.macrumors.com/article-new/2019/03/2019imac4kmulticore-800x482.jpg)" alt="" width="800" height="482" class="aligncenter size-large wp-image-686865" /> 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. <div class="linkback">Related Roundup: iMac (https://www.macrumors.com/roundup/imac/)</div><div class="linkback">Buyer's Guide: iMac (Buy Now) (https://buyersguide.macrumors.com/#iMac)</div> This article, "Intel's Coffee Lake Chips Bring Significant Speed Boosts to 2019 iMacs (https://www.macrumors.com/2019/03/28/2019-imacs-geekbench-benchmarks/)" first appeared on MacRumors.com (https://www.macrumors.com) Discuss this article (https://forums.macrumors.com/threads/2019-imacs-geekbench-benchmarks.2175505/) in our forums <div class="feedflare"> <img src="http://feeds.feedburner.com/~ff/MacRumors-Front?d=yIl2AUoC8zA" border="0"></img> (http://feeds.macrumors.com/~ff/MacRumors-Front?a=Bm5DDwmbl5Y:LxCBxgFpOSI:yIl2AUoC8zA) <img src="http://feeds.feedburner.com/~ff/MacRumors-Front?d=6W8y8wAjSf4" border="0"></img> (http://feeds.macrumors.com/~ff/MacRumors-Front?a=Bm5DDwmbl5Y:LxCBxgFpOSI:6W8y8wAjSf4) <img src="http://feeds.feedburner.com/~ff/MacRumors-Front?d=qj6IDK7rITs" border="0"></img> (http://feeds.macrumors.com/~ff/MacRumors-Front?a=Bm5DDwmbl5Y:LxCBxgFpOSI:qj6IDK7rITs) </div><img src="http://feeds.feedburner.com/~r/MacRumors-Front/~4/Bm5DDwmbl5Y" height="1" width="1" alt=""/> Source: Intel's Coffee Lake Chips Bring Significant Speed Boosts to 2019 iMacs (https://www.macrumors.com/2019/03/28/2019-imacs-geekbench-benchmarks/) |
