New 27-inch iMac 2017 benchmarks show it can play with the big Mac Pro boys

OpenCL performance

Shown below, the lowest-performing graphics chip in the new batch of iMacs provides better performance than the best graphics chip offered in the most recent group shipped in late 2015. This benchmark doesn’t test the chips for their gaming capabilities, but on how well they can handle simulating physics, processing images, and other tasks offloaded by the main CPU.

What’s important to note is that the Radeon Pro 580 and Radeon Pro 575 outperformed the AMD FirePro D700 graphics chip (93,028) in the 2013 Mac Pro. However, Poole notes that Geekbench 4 only measures the performance of one graphics chip at a time. Apple’s Mac Pro includes two FirePro D700 graphics chips with 6GB of dedicated video memory each.

That said, the Mac Pro’s FirePro D500 and D300 graphics chips reside toward the bottom of the benchmark chart, falling between the iMac 2015’s Radeon R9 M395 and the iMac 2015’s Radeon R9 M390 graphics chips. Two iMac 2014 models are also listed, with the Radeon R9 M295X scoring an 86,494 and the Radeon R9 M290X scoring a 76,507.

Here are the iMac 2017 benchmarks vs. the 2015 models:

Single-core CPU performance

Here, the listed 2017, 2015, and 2014 iMac models outperformed the four Xeon processors installed in Apple’s Mac Pro models sold in 2013. The latest “Kaby Lake” units provide a nice little 9 percent bump up from the previous “Skylake” generation, and a 20-percent single-core increase from the 2014 ”Haswell” generation.

Multi-core CPU performance

Although not shown below, it’s here where the 2013 batch of Mac Pros put a hurting on the iMacs. At the top of the performance totem pole is the Mac Pro’s 12-core Intel Xeon E5-2697 v2 chip, with a score of 24,562. Following that is the eight-core Xeon E5-1680 v2 with a score of 21,736. In third place, there’s the four-core Intel Core i7-7700K chip in the latest 27-inch iMac with a score of 18,945. After that is the Mac Pro’s six-core Xeon E5-1650 v2 processor with a score of 17,090.

Apple introduced its new lineup of iMacs in June, along with the all-in-one iMac Pro.
