With all of that, here are the results from this very large and interesting comparison... First up, the x264 video encode results.
To no surprise, the Intel Haswell Xeon E5-1680 v3 was the fastest of the systems being tested... Followed by the various Intel Extreme Edition $1000+ CPUs. Slowest in the farm was the Atom E3825 Bay Trail and AMD E APUs.
The fastest Intel systems can compile the Apache web server in under 30 seconds while the slowest systems take more than five minutes.
