Was AMD's K12 related to Zen in any way? AMD's predecessor to that, the Opteron A1100 series, was bog standard Cortex A57 cores. I figured K12 would be at best an evolution of a standard ARM design, but if it was more that would be very interesting. Would love to know more about this.

It wasn't a Zen variant; but the K12 was intended to be AMD's custom ARM uArch aimed at the server space. So there's a good chance it would have been focused on performance over power efficiency.

Power efficiency is an issue in the datacenter as well as you have to get that heat out, which also takes power.

I said over, as in relative to other ARM uArchs. Clearly, the power efficiency was the main draw of the proposal in the first place.
