Apple is set to unveil a major upgrade to its Mac Mini lineup this week, according to Bloomberg's Mark Gurman. The new Mac Mini, positioned between the consumer iMac and professional-grade desktops, is getting a significant overhaul. The compact desktop computer will shrink in size, resembling an Apple TV set-top box, and boast two ports in the front and three in the back on certain models.

The most exciting feature, however, is the addition of ray tracing graphics technique, a first for Apple's in-house silicon. This move is expected to make the new Mac Mini "the most impressive Mac yet" to utilize Apple's custom chip.

The Mac Mini is just one of several new devices Apple is set to announce, including a 24-inch iMac, a 16-inch MacBook Pro, and two configurations of the 14-inch MacBook Pro, all powered by the M4 chip. Additionally, Apple's rumored smart home display, similar in size to two iPhones side-by-side, will also make its debut.

This slew of new devices is poised to shake up the tech industry, offering a glimpse into Apple's vision for the future of personal computing and smart home technology. With its focus on custom silicon and innovative design, Apple is likely to set a new standard for the industry.
