Follow the headline link for all the details, watch the video below for more of a guided tour.

To me, these highlights stick out:

• Thunderbolt 4 implemented as a USB-C port (no change there)
• Daisy chain up to 4 Thunderbolt 4 devices
• Video: Support for two 4K displays or one 8K display.
• Data: PCIe at 32 Gbps for storage speeds up to 3,000 MBps.

And this from Apple:

“Over a decade ago, Apple partnered with Intel to design and develop Thunderbolt, and today our customers enjoy the speed and flexibility it brings to every Mac. We remain committed to the future of Thunderbolt and will support it in Macs with Apple silicon.”

Good stuff.
