Apple introduced new iMacs at WWDC 2017. I’ve taken a look at the 21.5-inch, 3.4GHz model with a 4K Retina display.
This model carries a 1TB Fusion drive and uses a Radeon Pro 560 with 4GB video memory. I’ll try to avoid repeating too many of the widely available technical details, but this is what I found:
Bright spark
The first time you start the new iMac you’ll be impressed by the brightness of its display. You can’t miss it. Apple claims it to be 43 percent brighter than before.
It isn’t just about brightness, not only is the Retina screen incredibly clear and capable of showing the image, but it also uses a clever technology called 10-bit dithering so it can reproduce “a billion colors”.
