I was doing similar comparisons of a cluster of 6 Pi 2s vs my Core i7, as well as DigitalOcean droplets, and I found that the i7 (quad core, single chip, running 6 VMs) was at least 20% faster in real world use, and using six DigitalOcean 1GB VMs was about 68% faster: http://www.pidramble.com/wiki/benchmarks/drupal http://www.pidramble.com/wiki/benchmarks/drupal There are tons of different use cases of course, and if measuring only raw CPU (not network, not IO, etc.), the benchmarks could be slightly closer, but I'm not going to recommend clients start ditching cloud infra for colocated Pi clusters :)
