Apple dusts off its epic 27-inch iMac all-in-one, updating it just enough to bring it up to 2017 standards for speed and features, and also to brighten its 5K display and giving it the ability to simulate more colors. The Cupertino giant incorporated 2017 versions of Intel processors and AMD graphics, and added support for Bluetooth 4.2, and replaced the old Mini DisplayPort connectors with two Thunderbolt 3-capable USB-C ports.
These humble updates were revealed at Apple's 2017 WWDC conference, along with similar spec bumps to the 21.5-inch iMac, the MacBook Pro lines, and MacBook. According to the reports, almost the whole Apple computer lineup has been refreshed for 2017 except for Mac mini.
In a recent report, new 27-inch iMac benchmark results have already appeared on Geekbench that claims the 2017 models are up to 15% way faster in multi-core CPU performance compared to previous generation models.
Apple's new high-end 27-inch iMac stock configuration with a 3.8GHz quad-core Core i5 processor with an average multi-core score of 14,886.Also, the GPU performance has upgraded considerably with an increase of up to 80% when compared to the equivalent 2015 model. Even the "low-end" Radeon Pro 570 in the 2017 model is speedier than the "high-end" Radeon R9 M395X in the 2015 model.
Both the Radeon Pro 575 and the Radeon Pro 580 outmatch the FirePro D700 found in the Mac Pro. Noteworthy, the Compute Benchmark only measures the performance of one GPU at a time.
Apple is set to launch the iMac Pro in December with workstation-class tech specs, which include up to an 18-core Intel Xeon processor, high-end Radeon Pro Vega graphics, up to 4TB of SSD, and up to 128GB of ECC RAM. The new iMac Pro will cost $4,999 in the US. While the new 27-inch iMac starting price is at $1,799 and the 21.5-inch models will be available at $1,099. However, prices vary by country.
