That's good news! AMD can finally have full stack.
Why is thunderbolt such a big requirement for a NUC equivalent?
I guess external GPU as well as pro-audio equipment. NUC is super small and handy (I have 3 of them) and powerful enough CPU-wise to do almost anything.
Is it possible to have an external GPU via USB-C that would be competitive to one via Thunderbolt? I understand that there may be nothing interesting as of yet.
No, USB-C doesn’t offer DMA.
Some of the new Intel processors come with AMD Radeon graphics, so...
