Its new 21.5-inch iMac with a Retina 4K display, due out next week, will come with a 8th-generation quad-core processor, and for the first time 6-core processors. The 27-inch iMac with Retina 5K display features up to 6-core and 8-core processors, making it twice as fast as the previous model.

The computers also come with an improved graphics chip that'll give video games and editing programs an 80% boost in performance.
