> I'm going to assume that a dedicated GPU was being used for Tomb Raider—they would have said something otherwise.
They said exactly what SoC they were using, and it's not known to have spare PCIe lanes lying unused in existing products. Apple pretty much just demoed an x86 game running on an overclocked iPad Pro.
They only said the demos were running off Apple silicon, not that they were running off a Mac Mini DTK machine.
They probably have other systems more akin to Mac Pros that they use internally.
It's not like Apple can't change what connectors are available on the back of the mac Mini. The form factor may not have changed, but the ports available have in the past releases.
Don't be surprised if there is no Thunderbolt 3 at all, but just USB-C.
It may be that by the time these things are ready for an actual release they can be USB4, which is USB-C + Thunderbolt technology, but no longer Intel exclusive.
