Leaked AMD Zen Engineering Sample Benchmarks?

That's not K12. Its Seattle. And it is anything but a success and downgraded more or less to a development platform.

Well, it's their first ARM design ever, so I wouldn't consider the current Opteron A series to be indicative of the possibilities of using ARM in servers.

This is not my area of expertise, but it does not jive with my personal experiences. The only way Intel was able to compete with their x86 technology in light phones and tablets (Merrifield and Moorefield) was by using their amazing process expertise to stay a few steps ahead in process node. The likes of qualcomm produced higher performance at lower power on larger process nodes than Intel's offerings here. If some of this power use success can be translated to the server farm / data center market, there would be billions in power savings.

Intel's problem in mobile is X86 is a very large architecture, and it simply doesn't shrink that well. As a result, it produces too much heat output to really be usable in mobile form factors. That's why the embedded world stuck with [and still uses] PPC, even as the rest of the world went x86. The only embedded x86 processor I've ever worked with are 286's, due in large part to their good thermal properties at the time those systems were designed. [There's a reason those >100nm fabs are still in operation; you'd be shocked how many systems still run on those ancient CPUs.]

From my experience:

Embedded: PPC [not to be confused with POWER]
Mobile: ARM
Everything else: x86/x86-64, with a sprinkling of POWER/SPARC/Itanium thrown in

By the time ARM has the performance to match x86, it's going to be just as power hungry, with less software and developer support. It's a good mobile design, but will never scale up the way some companies are banking on.
