The other interesting thing is that the NVidia Denver 64 bits core is also supposed to do some dynamic code optimization to map ARMv8 machine code to an optimized representation running over a very wide implementation. I'm sure the details are very different, but from a very high point of view it's two companies claiming to extract higher IPC and performance/power efficiency with some form of code translation running on top of a very wide underlying implementation. And in a slightly different way, Apple CPUs seem to be very wide and have a very good efficiency (no talk about dynamic code adaptation though). Maybe there's something cooking, with different people independently coming from different angles toward some new rough optimum? We'll see. I'm more interested in Denver right now, we'll get the Nexus 9 soon with real benchmarks to see the actual potential.
