You should ask for the specs of the laptops.
There seems to be just one configuration for the Acer Aspire ES1 711g as listed in the link below. It has Linux OS (not compatible with Windows and will not run Windows programs) and a Intel Pentium N3540 which is a low power entry level quad core CPU. It's weaker than a Core i3 CPU.

There are several different configurations of the Hp probook 470g2. There are two basic versions; one that uses AMD APUs and one that uses Intel CPUs. There are 3 different AMD APU and 8 different Intel CPUs for that laptop. Click the link below for details. Note that the Intel CPUs are listed in the "Graphics" section for some strange reason...
