While the event's main highlight was the iPad Pro model with a mini-LED display, Apple made sure that the iMac received its due performance upgrade. However, it seems that upgrading your 21.5-inch iMac with Intel's Core-i9 processor can result in better performance. > YouTuber Luke Miani has shared a new video in which he custom built a 21.5-inch iMac with Intel's Core-i9 processor. The results are pretty surprising as it manages to outperform Apple's latest and greatest M1-powered 24-inch iMac. Currently, you can buy the 21.5-inch iMac with an Intel Core-i5 chip. However, the machine was also initially offered with a Core-i7 processor as well.
