The jist of the claim made in the headline seems to come down to this passage:<p>> Overall, McIntosh-Smith says anything that is memory bandwidth dominated does well on ThunderX2 and at worst, is roughly similar to Skylake. However for more floating point-heavy applications, Skylake and Broadwell do better and are evenly matched because of the wider vectors, even though ThunderX2 cores strive to make up the difference.<p>It doesn't seem clear that they were making an apples-to-apples comparison to the Intel chips. I dunno.<p>Honestly I was hoping for more about just why ARM might be a good core for HPC. I'm slightly surprised that Performance/Watt were not reported, as I thought that's where ARM stood a fighting chance against chips like x86 and POWER.
