Why didn't Larrabee fail?
I'm not sold on the "<i></i> 1. Make the most powerful flops-per-watt machine." success.<p>From my knowledge that claim only makes sense for the ever-shrinking domain of applications that haven't been ported to GPGPUs with _simpler_ cores. I also don't understand how the best "flops-per-watt" can be extrapolated from the fact that the Phi is used in top ranked TOP500 machines.<p>The Phi really just seems like an intermediate between CPUs and GPGPUs in the ease-of-programming vs. perf/watt pareto curve.
