Highlights included a 42 percent faster iMovie test results 18 percent faster Handbrake times and 28 percent faster files and folder copy times.

It was also faster than the older iMac in all but the aforementioned Zip and Unzip tests. The high-end $1999 27-inch iMac was 15 percent faster overall than the 2012 high-end stock iMac. The new iMac’s Nvidia GeForce GT 755M graphics helped the system post 17 percent higher frame rates in the Cinebench OpenGL test than the GeForce GTX 680M graphics in the older iMac. The new model was 14 percent faster in our HandBrake Encode test 28 percent faster in our iMovie test. Like the 21-inch iMac, the new low-end $1799 27-inch iMac was also 5 percent faster overall than its predecessor.

We’re investigating this and will update this review when we have an explanation.

It’s possible that Haswell’s energy-saving features are kicking in as it waits on the slower hard drive to provide data to crunch. We also tried the Zip test with a 480GB Thunderbolt Helios +E2 drive, and the 2012 iMac was only a bit faster with the Helios, but the new iMac with Helios finished the task 130 seconds faster, in line with the older iMac. We saw that while the Haswell processor in the 3.2GHz 2013 27-inch iMac would run at a higher rate than the 2.9GHz Ivy Bridge processor in the 2012 27-inch iMac (both can go up to 3.6GHz in Turbo Mode), the Haswell processor often dropped as low as 800MHz, while the Ivy Bridge processors maintained a more consistent speed-falling to 1.6GHz occasionally, but not as often as the Haswell. Watching at the processor utilization during the Zip test, we noticed that the test uses a single processor.

At first we thought it was the hard drive, but both the 20 low-end 27-inch iMacs use the same 1TB Seagate Barracuda ST1000DM003 drives. Interestingly, all of the new iMacs were slower than their predecessors in our folder Zip and Unzip tests. HandBrake encoding was 17 percent faster on the new $1499 iMac. The 2013 2.9GHz iMac was 20 percent faster in iMovie, thanks to improvements Intel made in its Haswell processor’s Quick Sync Video feature. iPhoto, Photoshop and MathematicaMark scores were within 2 percent between these new and 2012 iMacs. The $1499 iMac was 5 percent faster overall than the 2012 2.9GHz quad-core Core i5 (Ivy Bridge) iMac it replaces. We used our Speedmark 9 benchmark suite to gauge the performance of the new iMacs. The high-end 27-inch iMac can be upgraded to include a 3.5GHz Core i7 processor for $200 and graphics can be upgraded from the 2GB GeForce GTX 775M to a GTX 780M with 4GB of video RAM for an extra $150. The 27-inch models can also be configured with 32GB of RAM for an additional $600. Options for the 27-inch models include the same storage choices as the 21.5-inch iMacs but add an available 3TB hard drive for $150, 3TB Fusion Drive for $350, or 1TB of flash storage for a cool $1000. The higher-end 21.5-inch iMac’s processor can be upgraded from the standard 2.9GHz Core i5 to a 3.1GHz quad-core Core i7 processor for another $200. Upping the RAM from 8GB to 16GB will cost $200. Available options for the $1499 21.5-inch model include 256GB or 512GB of flash storage ($200 and $500, respectively) or a 1TB Fusion Drive ($200) which marries 126GB of fast flash storage and 1TB hard drive into a single volume that performs much like an SSD, but with the capacity of a hard drive. If you think you might want a larger or faster internal drive, it’s best to customize your iMac at the time of purchase. While this and other changes help to significantly reduce glare on these recent displays, it makes it much harder to service the 2012 and later iMacs. The glass cover is adhered to the display, not held on by magnets like the aluminum iMacs released before 2012. The IPS screen gives the iMacs excellent viewing angles with no loss of contrast or color shifts as you move away from the center of the screen. The resolution of the widescreen displays remain at 1920 by 1080 on the 21.5-inch and 2560 by 1440 on the 27-inch iMac.

The new iMacs do not include Thunderbolt 2 ports found in the latest Mac Pros and MacBook Pros or FireWire ports found in iMacs predating the late 2012 models.Īs with its predecessors, the new iMacs feature glossy screens with LED backlights and IPS panels. These new iMacs have the same four USB 3.0 ports, dual Thunderbolt ports, SDXC card slot and gigabit Ethernet port as the late 2012 models.
