Notebookcheck has been a valuable resource for me. I use this site ever time I buy a laptop. You can compare almost any laptop CPU / GPU to any other.
As far as CPU’s go, and until Holomark excellent benchmarks are correlated and listed, Cinebench has good scores to look for.
I look especially for 64bit single, to know how things are going to for Design/CAD because it’s lightly threaded.
I look for 64bit multi for raytracing.
