I wonder what Ampere (mentioned in that article) is going to do. At this rate they’ll need to release a 1000 cpu chip just to be noticeably “different.”

At some point won't the bandwidth requirements exceed the number of pins you can fit within the available package area? Presumably you'll end up back at a low maximum memory high bandwidth GPU design.

I wonder how many of these you could cram into 1U? And what the maximum next gen kW/U figure looks like.

Unfortunately Ampere has fallen pretty far behind AMD. I don't see much point to their recent CPUs.
