The first Apple Silicon chip used in a Mac, the M1, implements Apple's first custom controller for USB4 and Thunderbolt 3 and delivers the platform's first systems meeting the new USB4 specification. Notably, Apple has brought USB4 to market about a month after Intel's own 11th Gen Tiger Lake processors for PC notebooks.

One of the big unknowns for the newest AMD Ryzen 5000 processors is whether or not there will be support on all 400 series chipset-based motherboards. After initially saying that these motherboards would not be supported, AMD reversed course and said it would work with motherboard vendors to enable support. At the point when the processors were launched, AMD confirmed that the schedule for the first beta BIOSes for 400-series motherboards to support Ryzen 5000 would be in the January timeframe. It would appear that ASRock has beaten that estimate by six weeks.
