"But from a whole datacenter perspective, I believe having servers with more cores is more efficient than having more servers with fewer cores, since data travels faster between more of the cores." How are you looking at this? From limited CompE background, my understanding was that moving data around core -> core burned a significant amount of power, even on the same die. (Using the comparison of one core vs two equally performing but separate cores)
