AMD is being very flaky with their rollout. They only provide the ML chip on some of their new chips, and let some vendors block it out in BIOS. I've been watching their github demo site, and they won't commit to anything but a very limited demo for Windows.
Intel at least released an open source kit earlier this year and will support their VPU on all Meteor Lake+ chips, as well as other processors. Consistency and openness is needed to break NVidia's deadlock here, OpenVINO could be a good step.
Meteor Lake will have 128GB/s for on-chip RAM bandwidth, that's a fraction of M-chips, it really remains to be seen how this will shake out, but it seems likely there will be a new class of computing device, and it may make all others very second class.
