I've sort of dropped this subject because I am busy with other things, but HPC workloads are not a uniform universe. As I have been repeatedly informed, latency is still a driving issue for many HPC workloads. I'd make the trade of latency vs. power, computational density, and/or bandwidth any day, but I don't know how many HPC users would agree.
