Apple is reportedly going to launch a new iMac soon that will come with an upgraded processor and display. Ming-Chi Kuo, an analyst with KGI Securities, says the company will sell 1 million iMac units during the third quarter, partly because of the new model. Leaks have suggested this 21.5-inch iMac will include a 4K display and it is possible an 8K iMac could be introduced at some point this year.

No confirmation about an 8K iMac has come from Apple, but a leak from LG, one of Apple's suppliers, said an 8K model is possible.

At the least, a retina upgrade for the smaller iMac could drive sales.
