But, of course, Apple's recent announcement at WWDC of its decision to move the entire Mac platform to its home-grown Apple Silicon over the next two years has raised serious questions about the future of the Mac - and also left many Mac users wondering about the wisdom of buying new Macs until Apple's future plans become clearer. The 27-inch iMac was already due for its annual update, having last been reviewed here in April 2019, so the arrival of a new model for 2020 is no great surprise.

Portal 2 test results showed the opposite effect, with the new Nvidia graphics showing a 7 percent advantage over the older Radeon graphics in the high-end models and 6 percent in the low-end models.ZDNet's recommendations are based on many hours of testing, research, and comparison shopping. (The $1999 iMac can be upgraded to 2GB of video memory for an additional $150.) The graphics test results were mixed Cinebench’s OpenGL test showed the older Radeon graphics to be about 6 percent faster than the new Nvidia graphics on the $1999 iMac, and 11 percent faster on the $1799 iMac. The 2011 iMac used AMD Radeon graphics, but Apple, as they are wont to do, has switched alliances for this generation, going with an Nvidia GeForce GTX 660M with 512MB GDDR5 memory in the $1799 model, and an Nvidia GeForce GTX 675MX with 1GB GDDR5 memory in the $1999 model. The new $1799 iMac’s zippy hard drive, larger amount RAM, and faster CPU all contribute to its increased speed. The new $1799 iMac 2012 was 28 percent faster overall than its predecessor, a 2.7GHz Sandy Bridge quad-core Core i5 system. (The 2011 iMacs came with 4GB of RAM.) The VMWare/ PCMark test loves that extra memory. This year’s model was 19 percent faster overall than the 2011 high-end iMac, 14 percent faster in the Cinebench CPU test, and 16 percent faster in our Handbrake test-the extra RAM in the 2012 standard configuration helps boost performance. The $1999 iMac was also faster than its predecessor, a 3.1GHz Sandy Bridge quad-core Core i5 system. In better news for the $1999 iMac, it was faster than the $1799 iMac in both the Cinebench CPU test (7 percent faster) and MathematicaMark (5 percent faster). While the Seagate drive is fast, it’s nowhere near as fast as the Fusion Drive in our custom-built 2012 27-inch iMac, which finished the 6GB file copy in just 41 seconds and had Blackmagic write speeds of over 310MBps and read speeds of over 400MBps. The $1799 iMac took 96 seconds to copy a 6GB file from one part of the drive to another, while the WD drive in the $1999 iMac took 146 seconds, the same result as the high-end 2011 27-inch iMac. When put into context with the results of the 2011 iMacs, this doesn’t seem to be a case of Apple choosing slower drives for the high-end model, it’s just that the Seagate drive is very fast.
I found read and write speeds between 180MBps to 190MBps on the Seagate hard drive, and about 120MBps on the WD drive. The $1799 iMac had an overall Speedmark 8 score that is 6 percent higher than the $1999 iMac.Īs a reality check, I ran Blackmagic’s Disk Speed Test, using the 5GB file settings. In fact, the $1799 iMac was faster than the $1999 iMac in nine of the 15 tests that make up our Speedmark 8 benchmark suite. The $1799 iMac was 34 percent faster than the $1999 iMac in the 2GB folder copy test, and 20 percent faster when uncompressing a 6GB file.
