I've seen it written about how personal computing has changed from "speeds and feeds" to things like battery life and portability. Up until now I have not really observed this first hand, but that has changed now that I have a new work computer.

The new EliteBook 745G3 has an AMD processor with four cores but scores lower using Geekbench than the HP ProBook 6460b that it is replacing, which is five years older! From a performance perspective, it would be better to keep the ProBook, but it is much larger and heavier than the 745G and that makes it desirable.

The 745G3 benchmarks slightly better than my 2010 Macbook Air. Note that both older computers have faster (> 2 Ghz) CPUs and fewer cores.

I find the comparison between the 745G3 and the Surface 3 fascinating. Both have 1.6 GHz, 4 core CPUs, the Surface 3 having an Atom processor, the EliteBook having an AMD. The multicore score is nearly the same, while the 745G3 has a much better single core score. 

The Surface 3 is the highest scoring of the computers that I own, while the new Mintbox is in second place.
