These new Macs will still support discrete GPUs. There’s no reason to think they won’t.Would not be at all surprised if the Developer kits have a GPU in them. Given they were supposedly driving the XDR display.The existing developer transition "Apple Silicon Mac" has USB-C (no thunderbolt), and is likely a modified iPad Pro with more RAM, rather than a Mac mini adapted to use Apple Silicon.
The standard Mac mini has Thunderbolt 3 supporting 4 x 4K displays, and also supports TB3 RAID & eGPUs. TB3 is basically PCIe over a cable. TB3 and PCIe are both tied to Intel processors. iOS devices don't support either.
However, the upcoming "USB 4" is supposed to roll in the features of TB3, meaning that Apple Silicon Macs (and iPad Pros) could support USB 4 in the future without needing an Intel CPU.

Apple could, conceivably, offer Macs with multiple SoCs, or offer new specialized coprocessor units similar to the Mac Pro Afterburner, an expansion card (on the very fast PCIe bus) that can rapidly accelerate tasks such as video rendering.
That said, the Holy Grail of "upgradable CPU engines" hasn't often delivered on expectations outside of the basic PC box, because modern MacBooks and mobile devices are deeply integrated internally and their parts wear out or grow obsolete basically in tandem.
A big gaming PC might easily benefit from a faster CPU or a graphics card update, but trying to add that sort of modularity to a light, thin device makes a lot less sense and creates new drawbacks. By the time your CPU is feeling slow, the memory and storage on your notebook are probably also due for an upgrade; the screen and keyboard and wireless and lots of other features also likely need to be replaced. So it's generally more useful to hand your old Mac to a user with more basic needs and buy a new one.
One exception to that might be the new Mac Pro, which is designed for upgradability. Apple could even sell upgrade logic boards for it, along with faster CPUs and GPU cards. These might even be more cost-effective than selling buyers new cases and shipping around those big heavy aluminum boxes. This would certainly be useful in places where people are installing rack-mounted units.
rob53 said:Good article but you left out how virtualization works and after doing a quick search of Apple's new Developer app, nothing showed up. Nothing for Rosetta either. Doesn't surprise me because it's probably a very proprietary set of software and hardware, which is fine with me.
I saw that Parallels released a blog article mentioned their prototype version of Parallels was used for the demo but nothing about which port of Debian was used. Their blog keeps saying to check back later. Has anyone been able to ask this question of any of the macOS Big Sur Apple people during a WWDC conference call? If Parallels only had to create an Apple Silicon version of Parallels (ok, Im stopping to say ARM because it's obviously a lot more than just ARM developers will have to content with) while macOS Big Sur using Rosetta did the "conversion" then that is also a huge step by Apple.

Current MacBook Pros have Intel Core chips with integrated Intel GPUs, and more powerful AMD GPUs that can be turned on when more graphics HP is needed.
