I assumed that 10gbit ethernet was only quietly released as an option for the M1 Mac Mini some time after the initial announcement, because Apple didn't want to commit to components where supply constraints could limit their ability to scale up production in the case of high demand.
Likewise, I wonder if there will be options for HDMI 2.1 (for 4K@120Hz), SD slot with UHS-III, and wifi 6E in the next few months for the new MacBook Pros.
- deergomoo 5y agoI expect the lack of HDMI 2.1 is bandwidth related. Full-bandwidth HDMI 2.1 is 48Gbps but Thunderbolt 4 is "only" 40. I'm not sure if they still do, but at one point each pair of Thunderbolt ports shared a bus, so you could have something on the left running at 40Gbps and something on the right running at 40Gbps, but not two things on one side. If that's still the case, the SD card slot and the HDMI port are probably sharing bandwidth with the one Thunderbolt port on that side of the machine.
- rz2k 5y agoThat's an interesting point. What interface do they use for the integrated display? It looks like there are multiple sets of chips involved in the physical ports for Thunderbolt or USB depending on what is connected.
